Quick tip- When the transmission overheats, shift to neutral, set the parking brake, and let the engine idle until the temp comes down. Depending on the transmission, shifting to park may be the exact wrong thing to do when it overheats because some transmissions don't circulate fluid through the cooler while in park. Not sure if that applies to your transmission, but every transmission I know of circulates fluid through the cooler in neutral, so unless you know that your specific transmission circulates fluid through the cooler in park, I would shift it to neutral instead of park if it overheats so I know that fluid is circulating through the cooler. Hope this helps you or someone else
@@Rolando083Unfortunately there is no simple answer. It depends on the vehicle and the conditions such as how close you are to maximum towing capacity and where you are measuring the temp, these factors can change the answer dramatically. For example, a light duty vehicle towing maximum capacity through big mountains in 100+ degree heat with no cooler other than the one in the radiator may easily see temps of 250 degrees or more at the pan, but a heavier duty vehicle with a good external trans cooler towing half it's rated capacity on flat ground in cool weather may never go past 160 at the pan. If you are measuring the temp of the fluid going to the cooler, you may see a temp 50+ degrees higher than the temp in the pan under heavy loads like accelerating hard from a stop towing maximum capacity up a steep grade. Most (not all) OEM transmission temp sensors measure the temp of the fluid in the pan. Under 200 degrees is ideal, every 20 degrees you go above 180 cuts the fluid's life in half, so adding a transmission cooler or upgrading the OEM unit to a larger one is a good investment if you are regularly seeing much high temps than that and you want the longest transmission life possible. Hope this helps
Yeah but if it doesnt lower for an hour or whatever and youre talking with onstar and they just say the transmission needs to be serviced.... you have to figure out wtf is going on... idling the engine ran my truck at that high trans fluid temperature and probably did more damage....i opened the hood and saw the fans in a struggle to spin like they were broken or thd fan clutch was broken.... i shut the truck down for a while with the hood open. (Canada temps -0celcius) and it cooled down in 15 minutes or less to 117c from 130 c i then was able to drive home after 3 hours of cursing and frustration....the fans worked fine once it cooled down. So why the f did they choose to not work then? Gm put the wrong tbv. Transmission bypass valve in them. It should have bee. 70cpm or w e units. But its a 90 cpm cfm ? That is installed from the factory.....another $200 part they should give us for free. Its easily accessible and easy to switch out from underneath the truck. Good work gm. You assholes
Mine was under filled by a quart from the factory...it would slip under WOT and I noticed temps running close to 210 just cruising around. Topped it off and it’s been fine ever since. Runs @ constant 192* while cruising, around 200* with 5k trailer.
221F is no big deal. I remember seeing some chart somewhere on the internet saying that transmissions prefer temperatures of 160F and if you go above that, like 180, transmissions will have a life span of only 50k miles. Not only is that false, but the source of that chart is from a manufacturer of transmission coolers ( basically I'm saying it's someone who has an interest in convincing people to buy coolers ). I have 2 trucks, a Cummins and an old 6.5 Detroit Diesel. On the Cummins, Alldata says I don't have to worry about the transmission unless it hits 275F ( I don't let it hit 245, but I've yet to see it hit 220 ), and on the 6.5 it says don't panic until 260F ( this one doesn't have a gauge, just an idiot light on the dash ). When you get to about 40k or 50k miles, have the dealership change the fluid in the pan. Not a transmission flush, almost all try to sell that, even to a buddy of mine. Tell them to just drop the pan, change the filter and the pan gasket, and replace the fluid that came out, nothing more. Having the dealer do it leaves a service record that the transmission was serviced and that it was done by them, so if anything goes wrong, they can't say that the failure was due to improper servicing. By the way, did you keep your old wheels and tires? Anytime the truck goes back to the dealership, remove your big tires and slap on the factory ones, so that if anything goes wrong with the drivetrain they can't void it because it was abused by the big tires.
Hey my rmps on my silverado went up to the 6 i was on the highway the oil and transmission gauges went high i stop and checked the oils hopped back in and the problem just stoped im changing the motor oil today machine reads 31% but when i removed the dipstick smoke came out, silverado 2014 5.3
Transmission cooler is In the ac condenser. If your Freon is low pressure switch won’t let the fans come on high. Will overheat your truck. Happened on my 2017 Silverado
Wow bro. I think this is my issue. My ac condensor cracked and leaked all my fluid and i hadnt had the chance to replace but i have noticed since then, my temps have been 220 or so. i guess i need to go on and ahead replace my condensor. i have a 2018
I need help I’m new to this u tube thing I have a 2021 gmc Denali 6.2 carbon pro I replaced my transmission fluid at 71 k and it was disgusting dark like engine oil so after a while I used a laser heat gun from snap on and measured the exhaust pipe at 468 degrees f the transmission pan at 356 f the dash temp said 76 degrees Celsius the exhaust pipe is about 2 to 3 inches away from the transmission pan wtf !!!!!
Mine overheated a few times in the summer...it was able to cool down....but two nights ago the thing overheated but wouldnt cool down... once i got out of the way of speeding traffic coming off of the highway I barely got off of, I opened the hood to help cool it because its cold out...the rad fans were doing struggle to spin movement then spun once and stopped. Repeated that cycle for a while until i turned the truck off. Following their instructions on the dash (idle engine) for 2 hourz wasted half a tank of gas and ran the transmission at the high temperature for that long period of time.. once I was able to drive home....and it was cooled down to 117c. From 140.c. the fans were spinning like nothing ever happened. Freely and constantly. So anyone have any idea why the fans stopped when the most critical moments of needing that fan happened? Its not a relay or fuse because it works fine now.....DONT LET YOUR TRANSMISSION GET DAMAGED BY FOLLOWING GMS IDLE ENGINE TO COOL TRANSMISSION PROMPT SCREEN ON THE DCI!!! *****If it doesnt start lowering trans fluid temps while idling*****
Just bought a 16 Silverado 1/2 ton 5.3 with 58.000 miles and only put 300 miles on the truck and seen metal in the transmission oil. Thank god for factory warranty!! Once when I get it back the transmission thermostat is getting removed. And the v4 to v8 is going away. The reason why they did this is so the oil will get less dense and to improve mpg.
Had to replace my torque converter and transmission pump replaced at 94000 miles my transmission eradically shifts from time to time been doing it since i bought it brand new chevy is junk period, my old secretary at work had to trade in her equinox because of her tramsmission too!!!!
The pressure line going into the radiator that turn in the line before it goes in radiator.. it was stopped up .. dropped the pan put new filter on, didn’t fix , after that .. was when I found the stopped up line .. it run 280 but never shifted bad .. just got all get out ..
Just drove my 2007 Suburban over 4500 miles pulling a 3900# Geo Pro camper. We went from Louisiana to Sequoia National Park and back, Temps ran up to 242 degrees on the transmission gauge several times for long periods, and about the same on the engine temp, Used the tow/haul button the entire time. Has factory installed tow package with trans cooler. Had some real hard pulls through NM, Ariz, and California with speed dropping down to 40's on a few grades 6. The vehicle has 281,000 miles and never had the fluid changed. I believe if you stay below 260 your fluid can survive, wonder how many more miles she may have in her?
A year ago, my 4L60 overheated and I didn't catch it in time when I started feeling stuttering and my temp gage pegged at 250°. Added a small cooler after the radiators internal cooler. Drove several more thousand miles without breakdown. I have been keeping it below 210 as much as possible. Yesterday after a long climb, transmission had already been hitting 230° I had to pull over a lot. Now, it wants to overheat. I think fluid is done.
My ‘14 Silverado 1500 4x4, 5.3L, trans temp running no load, straight highway, 90 outside temp, is averaging 196-199. Stop and go traffic, 90 outside temp, runs around 205-208. I will be installing a trans cooler.
2007 Suburban 1500 5.3L transmission temperature with no load has reached 212 on highway in 90 degree weather. Stop & go traffic it hits 205. I just bought a cooler today I will be installing it asap!
What are your rpms @ when doing 75 and are you lifted on bigger tires. My 2010 is getting up to the 208 temp empty have 145k miles on it, im thinking i need a better cooler since i live close to the desert. So 90+ weather. Its a daily driver.
Have you installed a cooler yet? I just did the sure cool SL010 kit on my 2015 4.3 silverado and it hasn't gone over 175 yet. I read about people still running hot after the pill flip or surecool mod since we don't have an aux cooler like the v8s do. I want to add a trans cooler for preventive measure.
Dude 221f is not overheating a transmission. Especially if you are depending on the factory sensor which is normally in the valve body or post pump. Typically your trans pan temp is 10-25F lower as well. I wouldn’t even worry about the factory sensor location reading up to 235F+ and that’s still in the safe operating range.
I have a 2016 Tahoe did the tempo delete but when I’m driving temp 158 to 170 but when I’m in parking o on heavy traffic my temp goes its goes up to 230 any tips what could I do
Possible cause of your overheating issue.... U-haul box trailers are equipped with surge brakes. When you drive forward and step on your brake the weight of the trailer pushing against your hitch ball pushes a hydralic cylinder that turns on the trailer brakes. When you back up with the trailer, usually the brakes will not activateon level ground however when you back up on a grade the trailer brakes will drag. I have seen trailers with surge brakes lock up when a truck was backing a loaded trailer. With the trailer brakes dragging while backing up the torque converter in your truck will beat the transmission oil and heat it up fast, especially when there is little or no air going through the radiator which contains the transmission cooler. There is a lever on most surge brake systems that disables the piston that activates the surge brakes for the purpose of backing up the trailer. If you did disable the surge brakes before backing the trailer please disregard.
My 2010 4.3 silverados transmission temp jumps from 170/190 to 277/244 but then goes down to 160, it just all over the place. I replaced the TCM, and had the transmission serviced. It shifts fine, even before it was serviced, so no problems there, I get the warning "transmission hot idle engine" after 20 miles or so driving it.. Any ideas? Thank you.
I had my transmission temp at 172 degrees Celsius. Which is 341.6 farenheit. Got the truck stuck on a lake going ice fishing. I didnt have the transmission fluid temp screen on when I was on the lake. So I didnt even know it was overheating. I looked down at my cluster and had a message. Transmission hot let engine idle. Took 25 min in negative 20 celcius to cool down. Had check engine light on and stabilatrack and traction control lights on for 1 day after this happened. Then it all shut off. Never had an issue since. Also I was in 4 low.
Mine did the same thing today. Warning chimes and flashes the engine in idle on screen you speak of. Unfortunately I was 2 hours away from home. Had to limp it home with noticable issue. Got home and added fluid. Started the truck up and it right a way climbed up to 200 degrees. So I shut it off. Now what?
Wow shit was probley boiling, the hottest I seen my trans temp get to in my ram was 215 degrees fahrenheit trying to pull a stump out of my yard in 4low
While plowing working the truck super hard I’ve gotten up to 240s 250. Truck was fine. I’ve since replaced the fluid with amsoil heavy duty trans fluid and did the thermostat bypass and it’s kept the temps way down. However if you live in a cold climate unless you use a fluid that can stay liquid at very cold temps like amsoil stays fluid up to -85f. If you use standard cheap fluid you’ll burn the trans up.
Shift technologies lower temp transmission thermostat! Regular driving mine stays around 145 towing the highest I've seen 175! The best part is there only like $38!!!
Joey Scott ... Will it fix what? Trans fluid temp? Yes, it will drop down. Engine temp is within that level you said (210) but at low load it can drop to 190-195 F (plug an OBD II to get the exact reading.
i have the opposite problem. i cant get my trans. to operating temp. i am not able to get it past 140F. thats not good , the operation temp. should be 170F - 185F.
@@joeyscott9250 Intermittently hitting that temp every once in a while isn't that bad for synthetic fluid. However, running that hot continuously will degrade the fluid twice as fast as running a 180 would, and if the fluid breaks down and isn't changed, the transmission's longevity will suffer. Every 20 degrees you go over 180 cuts the fluid's life in half. If I was regularly seeing temps of 195+ and I wanted the maximum possible longevity out of the transmission I would install a cooler, but that's just me. Hope this helps!
I know this is an old video but the major problem is with chevy silverado is that the GM sends transmission fluid into a side tank of radiator that sits at 210° . This is a problem because this is normal temp for the coolant but transmission fluid doesnt like this. Heat will transfer from that radiator to the side tank. Heat goes to a cooler place. Best thing you can do is eliminate that and install a stand alone cooler like the Derale cooler with fan. They work awesome
I have a 2011 Silverado 4.8 4x4 And I was at the drive thru at MCdonalds And I saw it slowly climb from 198 degrees to 220 degrees in like 5 minutes🤔 Idk what happened, no abusive driving, not hauling anything. And trans fluid is still a pretty good color. Not dark
The transmission cooling lines go into the cooler in the radiator first, this actually heats the transmission, on my Chevy I eliminated the cooler in the radiator, I now have 2 transmission coolers in front of the radiator, both have electric fans run by a temp sensor for on at /l175 degrees off at /125 degrees. Solved my issues
So me pulling a camper of 6200 lbs in my 2019 chevy silverado 1500 z71 trail boss my transmission got up to like 270 and check engine came on they replaced the torque converter and something else now yesterday I towed the same camper and got to 250 but truck says u can haul up to 7000 lbs what is really going on and this was only a half hr drive
Yeah dude it’s wild. I ended up upgrading to a 3/4 ton diesel to be safe. Can’t understand either why they rate 1/2 ton trucks to 7-9k but they struggle with temps and whatnot. Now, I’ll pull 12-14k with my diesel and the trans never gets over 160 degrees!! Lol
A few things one the thermostat on the side of transmission to these trucks have DOD and it causes the torque converter to slip need to turn off the DOD are you have torque converter failure which they’re known for because of the DOD
Got a question to ask? I have a 2012 Chevy Silverado 1500 lt 5.3 and the trans temp normally runs around 150 when driven normally but the recommended temp is supposed to be between 175 and 200 I had it up to 181 one time because I was driving aggressively! I don't understand how it don't reach a normal temp of 175 when driving normally but the stock trans Gage might be off to!
Gauge could be off, fluid could be a different viscosity than what’s recommended, or I’d say someone could’ve bypassed the thermostat keeping fluid running continuously to keep her more cool than stock if it’s preowned. Those would be my top guesses.
tru-cool transmission oil cooler will slam the heat, regular heat is 75-95 C , oil cooler will make it 50C and not above 80C when youre carrying stuff or doing pressure on the car
After driving my 2020 Silverado 1500 in the sand in NC, I noticed the trans was running around 230 in the sand but at 175 on the road. Iv been told this is nothing to worry about as long as I follow the recommendations fluid change intervals. As long as it doesn't stay hot in normal conditions, there's nothing to worry about.
I always take my truck up to the lake with some steep inclines and my transmission temp is always around 190. Recently I went up to the lake again but this time I used tow/haul mode because I read it will be easier on the transmission. That day my transmission temp went up to 230 degrees.
Wow so much horrible advice with no real knowledge was given to you. Your torque converter slips when you are moving slowly and even worse in reverse with a load behind it. Reverse is geared at 3.064 vs 1st gear at 4.027 so it will cause more torque converter slip/heat to get the load moving. 221 is nothing to worry about but in the future just put it in 4low in these situations and you'll never have elevated temps since the torque converter will be spinning fast enough to lock. FYI your thermostat definitely doesn't know what direction your truck is moving, it strictly open and closes based off of temp.
So the advice is to generate more heat with gearing it lower in 4wd?? An driving in 4wd at all times when hauling. Great advice, add trans cooler delete the inline thermostat, an if you have to change the tq to a better aftermarket one. Why generate more heat, in motor and trans am transfer case which higher rpms at all times in 4wd. These trucks tq is defective from the dealer an it’s hard to get them to replace it under warranty. Eventually the slipping is gonna send enough metal through your trans an trans pump causing major failure. Cooler thermostat an new tq on the after market side.
Converter lock up is controlled by the TCM, and never happens in reverse. It also pretty much never happens under a high throttle situation unless you have HPTuners or such and change the parameters. Best advice is to invest in HPTuners, Delete DoD/AFM, set 1-4 to never lock to save the converter, and only lock the TCC in 5-6 at low throttle. Bypass the cooler Tstat or invest in Superior Transmission part to set it to 135 if u live in cold environments, and install the LONG TRU_COOL 40k GWV LPD Transcooler. On my cammed 6.0 Denali I have the radiator bypassed also because it has a 3k Stall in it with a built 4l60e, my 14 Sierra has the stock converter and it daily driver so it goes thru the radiator also which warms it up fine in Southern cold weather. The weakness in the 6l80 is the converter from an OEM viewpoint, look at the TSBs.
Never had any issues with my 17 High Country 6.2L overheating but I changed/flushed the 8 speed to Amsoil ATF when it left the dealership took that OEM crap out.
@@Buuboi214 explain this shutter , i want to know. Mine makes a ticking noise from the valvebody in second gear as i press lightly on the throttle but goes away if i step on it more. No noise if its in tow mode. Dont know if its weak springs for the pressure in the valvebody ports?? Dont have a shift kit installed.
Have a 2015 GMC Double cab 4.3 in South Texas. Yesterday noticed it got up to 216 going on a slight upgrade was going 80mph had to slow down to 65mph to start cooling down. I know it needs a fluid change thinking flush or just change the filter and what is in the pan top it off?
My 08 silverado is going up to 215 to 230 engine and trans when towing my camper. It will maintain there at 60 mpg for majority of a trip. Is that bad?
My 15 has a 2899 stall, when it reaches 189 degrees it starts to shake/vibrate. Any fix for that? My trans guy says this new mobil fluid he is changing next week will/should fix it.
I have a 2019 Silverado 1500LD and I've never had transmission issues. I bought it for straight long distance towing and my transmission temp loaded with 9k going up steep grades has never been over 195°F P.S bought it 6 months ago now have 30k on the odometer.
Any shuttering issues like the truck is missing when going uphill before it downshifts? I just bought one a week ago and the thing bucks like crazy when I go up a hill before it downshifts.
I got the same truck brother. The transmission seems fine. I notice every once in a while it shifts a little weird but I havnt had to take it in or anything.
I have a 2014 High Country & never seen the trans temp go higher than 195f. I have 99,500 miles on it.. any shutter or weird shift I had before was gone when I disabled the AFM system.
Part of the problem is the 190 thermostat gm started putting in the lines on the transmission. Trans fluid breaks down at 160 Degree’s. Delete the thermostat you’re welcome. Ima replacing my trans in my 2014 as I type this. 4600 im sure the 8 speed is a thousand more lol. 183k miles she decided she wasn’t gonna take it no more.
My 18 Silverado ran hot today. Which led me to this video. Why does the traction control light co.e on when trans overheats? I can't find any help in the owner's manual. I was on the interstate doing 80mph with a dirt bike and gear in the back. I wouldn't consider that a heavy load. Any advice for the future of my trans would be appreciated
I do not recommend flipping the piece in thermostat block” flipping the pill” that’s what they call it. I have 2017 Silverado 5.3. 81,000 miles my temperature was running 180 190 I went on Amazon bought the superior solutions cooler flow bad pass valve kit very easy install really nothing to it comes with very detailed instruction. Very happy with the product transmission now runs 112- 134 I believe I paid something around 40 bucks absolutely worth every penny. Also, I would change the transmission fluid hell of a lot cheaper than a transmission down the road. Damn sure not gonna hurt it. Hope this helps you.
Hey guys can y’all help me out, I have a 2015 xlt Ford, so my transmission temperature keeps rising to 230 and my fans will not come on, and I’m afraid my truck will overheat. Note my A/C coolant is low it doesn’t shoot cold is that a fracture to why my transmission fluid is overheating.
Can anyone give me a hand? I bought a 2018 Silverado 4.3L 4 months ago with 40k on it. It was having bad issues when it goes in to 4 cylinder mode. So I talked to the head mechanic at my dealership and he told me to buy a chip that keeps it from going into 4 cylinder so I did. I’m driving it for the first time and I am 4 hours into an 8 hour drive and I noticed it stopped shifting while on the highway then I saw white smoke so I got off the highway. As I was parking the trans overheating warning light came on. Anyone? There is a fluid that went so that’s what I’m assuming the white smoke was from but there is plenty of trans and oil and coolant in the truck. Any help? Thanks.
Thank you for your helpful information, I am from Saudi Arabia and the weather here is extremely hot so you can imagine how the transmission temperature will be , two days back I bought a Ford F-150 v8 2019 (10 speeds) and I begin to experience some heating issue with my transmission reaching up to (222 F) ...I wonder if that’s normal or not ..I was driving gently in the desert with my air condition closed
Wasn’t hauling anything and reached 284°F today and the dealer I got it used from acted like it would be fine even though I know better and I wasn’t even hauling anything was just me and my wife and neither of us are built oversized lol
Man this video was about 4-5 years ago now… I honestly can’t remember what was typical with this truck. I know my current Cummins generally stays around 168 at normal operating temps.
My transmission temperature very low all the time.it that bad?after 4.5 hours straight driving from Vegas to new port California my transmission temperature was 178 degrees.when I just driving around town 120-130 degrees
Farid Gadimov you have the 6.2l?? I believe they do run colder by design with a factory built in trans cooler... the 5.3s don’t have that. The trans runs off the same piping our radiator does so they end up running a little warm all the time.
220* for a short time is no big deal. If it had stayed at 250 plus for a while is when it starts to break down. My 18 sierra 6.2 with the 8 speed trans has a heavy duty trans cooler that is built into the A/C condenser; yours may have one also. Go to the dealer give them your VIN and have them print out all your RPO codes so you know what your truck has.
Well damn... my ‘15 Silverado (company truck) digital readout for my transmission was at 284° the other day hauling a bed full of tools/materials up a mountain.. after reading these comments I’m going to have it checked out and serviced. Once I switched over to “manual” and selected the gears individually and activated the tow/haul feature it dropped back to 220°ish. Will see what the mechanic finds... fortunately I won’t have to pay for repairs, I’d never abuse a company vehicle, but I try to have it serviced when needed. Thx
The radiator was low on antifreeze, and there apparently was a very small birds nest covering the radiator. I was told if the radiator is low on juice, the transmission overheats BEFORE the trucks temp overheats. If you’re running into a similar issue then check your antifreeze/coolant levels!!!
Ismael Perez i don’t know how low the antifreeze was... by that point it was in the shop. But the mechanic explained that the way those trucks were designed when the radiator was low the transmission would heat up first, then the motor. Kind of weird
Nestor M Palaquibay 205 isn’t going to hurt anything, mine does it often while cruising big hills and occasionally in 4x4. Wouldn’t let it get up over 230ish though
Did mishimoto transmission install without the bypass valve delete and was getting same temps driving on the highway with 95 degrees outside.. was getting 180 and went up to 199 without tow. Consider doing the bypass valve delete but here in Central time zone it gets cold.
Cover the exhaust baking the trans pan and the trans lines going by the catalytic converter. A cool trans is better than a burnt one. Do the thermostat mod, the cash will stay in your your wallet.
I have a 2017 Chevrolet Silverado 2WD just about to hit 100K mi trip to Arizona my truck slipped gears and then over heat + 220 transmission fluid’ I added fluid and towed now it went down but should I delete thermostat ? It should work to cool down lines I’m hearing?! Great video describing similar situations
That's not hot. Not even close. Synthetic trans fluid is good to 275°. I've had mine up to 240° with no issues. If you tow occasionally, don't even worry about it. If you tow heavy and often. Then adding an auxiliary cooler and doing fluid changes periodically and your golden. But your worrying about nothing.
Duuuuude made this video well over a year ago and not a single person made that realization! That makes total sense now! Was a bitch to get up there! Haha
Had my transmission fluid get to 252 degrees on my 14 z71. I was about 3 hours into a pretty challenging off-road trail in Colorado when I checked and saw it was at 252, immediately shut the truck off and let it cool for 30 min. I haven’t noticed anything weird with the transmission after that but I will be doing the thermostat mod soon
What is a thermostat mod? Is it a "thermostat delete" as some people are saying? If so, how will that hell the temperature of the transmission? Thanks!
I do mine every 50k miles and still comes out nice and red. Some color in the filter that it is working and picking up clutch material. 60 is ok still.
I took my 14 Silverado to GM about my transmission slipping between 2nd and 3rd gear they told me they just got a bulletin from GM they know about the issue they told me to put it in reverse before I put it in Drive to purge the air out of the transmission does anybody else know about this issue
my 2009 silverado, i pull 2 tons on a 16ft trailer, the temp goes up to and sometimes maintains 230f even 240. its been like that for years . is that bad?
Rob Calton should probably take a look at the transmission fluid and see what temp it’s rated for before losing its lubrication abilities.. a lot of ppl tell me to change it out if I ever come close to hitting 250 degrees
My 2014 z71 blew my trans on a trip back from Florida to Houston it was jerking hard but it got me home 147k miles 300 more and the warranty wouldn't have covered 3k out of the 5k repair they put a "new" one it is very shiny
@@JohnWargo93 yes anytime your transmission fluid gets over 200 degrees it depletes the life of your transmission , it might not get 50000 miles out of it
Cool vid bud. Never had that happen in reverse towing, so I never thought about that one, but mine had run hot since the day I drove her home. Did the t-stat mod myself a few years ago and ran duel coolers. 2014 Rocky Ridge(over priced ball and chain) Shakerado 5.3l This truck still had the original 3.42 gears in with a 6" lift, 35's on 20's and on it's 3rd torque converter when I finally made a few changes to GM's "brilliant"(insert sarcasm here) engineering. Has run low 120's cruising interstate for hours on end(weekly 5 hour commute) since except for a few abnormally scorching summer days got up to low 130's. You may not need duel coolers depending on tire size, gears(overall strain on driveline), but if you go that route make sure to run them in parallel with each other, otherwise the effects of the pressure drop will eventually show their ugly face in the pump(scouring) and TC. A couple manually switched or temp controlled fans for stop and go and a manifold with a manual bypass ain't a bad idea either. Had to make up a manifold winter before last since trans wouldn't get any hotter than 100.. Hope this is helpful. Apologies for writing a book. Fingers just won't quit adding shit.. lol
John Short thank you sir! I might go a little smaller soon myself, trying to start hot shotting cars and equipment. These 33x12.50s are a little uneasy for towing I think. Lol
my 2016 silverado is heating up to 270 - no lights or issues happening but I am bringing it to the dealer to look at it. I also have an extra trans cooler
You didn't share anything new other than your towing trip caused your transmission temp to rise in two different occasions, I thought you had done your research with important transmission video info. I clicked on your video thinking you were going to describe normal operating temp vs. maximum allowed operating temp and how to prevent it / when to get your transmission checked.
Quick tip- When the transmission overheats, shift to neutral, set the parking brake, and let the engine idle until the temp comes down. Depending on the transmission, shifting to park may be the exact wrong thing to do when it overheats because some transmissions don't circulate fluid through the cooler while in park. Not sure if that applies to your transmission, but every transmission I know of circulates fluid through the cooler in neutral, so unless you know that your specific transmission circulates fluid through the cooler in park, I would shift it to neutral instead of park if it overheats so I know that fluid is circulating through the cooler. Hope this helps you or someone else
Avery Alexander thanks for the info brother!!
What's a normal temperature when towing?
@@Rolando083Unfortunately there is no simple answer. It depends on the vehicle and the conditions such as how close you are to maximum towing capacity and where you are measuring the temp, these factors can change the answer dramatically. For example, a light duty vehicle towing maximum capacity through big mountains in 100+ degree heat with no cooler other than the one in the radiator may easily see temps of 250 degrees or more at the pan, but a heavier duty vehicle with a good external trans cooler towing half it's rated capacity on flat ground in cool weather may never go past 160 at the pan. If you are measuring the temp of the fluid going to the cooler, you may see a temp 50+ degrees higher than the temp in the pan under heavy loads like accelerating hard from a stop towing maximum capacity up a steep grade. Most (not all) OEM transmission temp sensors measure the temp of the fluid in the pan.
Under 200 degrees is ideal, every 20 degrees you go above 180 cuts the fluid's life in half, so adding a transmission cooler or upgrading the OEM unit to a larger one is a good investment if you are regularly seeing much high temps than that and you want the longest transmission life possible. Hope this helps
Yeah but if it doesnt lower for an hour or whatever and youre talking with onstar and they just say the transmission needs to be serviced.... you have to figure out wtf is going on... idling the engine ran my truck at that high trans fluid temperature and probably did more damage....i opened the hood and saw the fans in a struggle to spin like they were broken or thd fan clutch was broken.... i shut the truck down for a while with the hood open. (Canada temps -0celcius) and it cooled down in 15 minutes or less to 117c from 130 c i then was able to drive home after 3 hours of cursing and frustration....the fans worked fine once it cooled down. So why the f did they choose to not work then? Gm put the wrong tbv. Transmission bypass valve in them. It should have bee. 70cpm or w e units. But its a 90 cpm cfm ? That is installed from the factory.....another $200 part they should give us for free. Its easily accessible and easy to switch out from underneath the truck. Good work gm. You assholes
Appreciate the tip 🤝
Video starts at 4:12
thank you omg
Yeah and too many "Basically"
Mine was under filled by a quart from the factory...it would slip under WOT and I noticed temps running close to 210 just cruising around. Topped it off and it’s been fine ever since. Runs @ constant 192* while cruising, around 200* with 5k trailer.
That’s hot
Hope you did the mod on the thermal bypass
Transmission coolers come standard on Silverados, 2017 Silverado 1500 6-speed uses Dexron VI which is good to 285 degrees
Really nice to know Iam seeing 250
Yes but don’t the seals and shit in the trans fuck up at like 230°
221F is no big deal. I remember seeing some chart somewhere on the internet saying that transmissions prefer temperatures of 160F and if you go above that, like 180, transmissions will have a life span of only 50k miles. Not only is that false, but the source of that chart is from a manufacturer of transmission coolers ( basically I'm saying it's someone who has an interest in convincing people to buy coolers ). I have 2 trucks, a Cummins and an old 6.5 Detroit Diesel. On the Cummins, Alldata says I don't have to worry about the transmission unless it hits 275F ( I don't let it hit 245, but I've yet to see it hit 220 ), and on the 6.5 it says don't panic until 260F ( this one doesn't have a gauge, just an idiot light on the dash ). When you get to about 40k or 50k miles, have the dealership change the fluid in the pan. Not a transmission flush, almost all try to sell that, even to a buddy of mine. Tell them to just drop the pan, change the filter and the pan gasket, and replace the fluid that came out, nothing more. Having the dealer do it leaves a service record that the transmission was serviced and that it was done by them, so if anything goes wrong, they can't say that the failure was due to improper servicing. By the way, did you keep your old wheels and tires? Anytime the truck goes back to the dealership, remove your big tires and slap on the factory ones, so that if anything goes wrong with the drivetrain they can't void it because it was abused by the big tires.
John Davis duuude thanks for the info!!! And yes, I keep the stocks around for winter, PA inspections, and absolutely any dealer trips!!!
Hey my rmps on my silverado went up to the 6 i was on the highway the oil and transmission gauges went high i stop and checked the oils hopped back in and the problem just stoped im changing the motor oil today machine reads 31% but when i removed the dipstick smoke came out, silverado 2014 5.3
Transmission cooler is In the ac condenser. If your Freon is low pressure switch won’t let the fans come on high. Will overheat your truck. Happened on my 2017 Silverado
Wow bro. I think this is my issue. My ac condensor cracked and leaked all my fluid and i hadnt had the chance to replace but i have noticed since then, my temps have been 220 or so. i guess i need to go on and ahead replace my condensor. i have a 2018
@@mylesjay15 hopefully that helped you out
Is this also the case with 2500s?
Every single pickup truck should come with a separate transmission cooler, no questions asked. But then again….
I have the single cab 221
Turn a/c on makes cooling fans run faster
I need help I’m new to this u tube thing I have a 2021 gmc Denali 6.2 carbon pro I replaced my transmission fluid at 71 k and it was disgusting dark like engine oil so after a while I used a laser heat gun from snap on and measured the exhaust pipe at 468 degrees f the transmission pan at 356 f the dash temp said 76 degrees Celsius the exhaust pipe is about 2 to 3 inches away from the transmission pan wtf !!!!!
All normal 1500s run around 190. Mine just keeps climbing. Replaced fluid and filter. Still running hot. 2018
Did you find out the culprit?
What was it finally?
@@elibojorquez7188 the thermal valve
Mine overheated a few times in the summer...it was able to cool down....but two nights ago the thing overheated but wouldnt cool down... once i got out of the way of speeding traffic coming off of the highway I barely got off of, I opened the hood to help cool it because its cold out...the rad fans were doing struggle to spin movement then spun once and stopped. Repeated that cycle for a while until i turned the truck off. Following their instructions on the dash (idle engine) for 2 hourz wasted half a tank of gas and ran the transmission at the high temperature for that long period of time.. once I was able to drive home....and it was cooled down to 117c. From 140.c. the fans were spinning like nothing ever happened. Freely and constantly. So anyone have any idea why the fans stopped when the most critical moments of needing that fan happened? Its not a relay or fuse because it works fine now.....DONT LET YOUR TRANSMISSION GET DAMAGED BY FOLLOWING GMS IDLE ENGINE TO COOL TRANSMISSION PROMPT SCREEN ON THE DCI!!! *****If it doesnt start lowering trans fluid temps while idling*****
Just bought a 16 Silverado 1/2 ton 5.3 with 58.000 miles and only put 300 miles on the truck and seen metal in the transmission oil. Thank god for factory warranty!! Once when I get it back the transmission thermostat is getting removed. And the v4 to v8 is going away. The reason why they did this is so the oil will get less dense and to improve mpg.
You need to replace your thermal bypass valve watch videos on it new ones open up at 158 supposedly !!!
Had to replace my torque converter and transmission pump replaced at 94000 miles my transmission eradically shifts from time to time been doing it since i bought it brand new chevy is junk period, my old secretary at work had to trade in her equinox because of her tramsmission too!!!!
The pressure line going into the radiator that turn in the line before it goes in radiator.. it was stopped up .. dropped the pan put new filter on, didn’t fix , after that .. was when I found the stopped up line .. it run 280 but never shifted bad .. just got all get out ..
Just drove my 2007 Suburban over 4500 miles pulling a 3900# Geo Pro camper. We went from Louisiana to Sequoia National Park and back, Temps ran up to 242 degrees on the transmission gauge several times for long periods, and about the same on the engine temp, Used the tow/haul button the entire time. Has factory installed tow package with trans cooler. Had some real hard pulls through NM, Ariz, and California with speed dropping down to 40's on a few grades 6. The vehicle has 281,000 miles and never had the fluid changed. I believe if you stay below 260 your fluid can survive, wonder how many more miles she may have in her?
Almost 300k that’s awesome!
I have a 2007 suburban ltz aswell and my temps gets to 227-237 is that ok? Just tought I was a little hot but reading your comment made me feel good
I just got back from a 12 hour trip and my trans temp on my 2015 ram 1500 was at 230.
A year ago, my 4L60 overheated and I didn't catch it in time when I started feeling stuttering and my temp gage pegged at 250°. Added a small cooler after the radiators internal cooler. Drove several more thousand miles without breakdown. I have been keeping it below 210 as much as possible. Yesterday after a long climb, transmission had already been hitting 230° I had to pull over a lot. Now, it wants to overheat. I think fluid is done.
No your transmission is done. You can try to change the fluid but generaly if it's hard to keep the trans cool in normal towing its slipping.
My ‘14 Silverado 1500 4x4, 5.3L, trans temp running no load, straight highway, 90 outside temp, is averaging 196-199. Stop and go traffic, 90 outside temp, runs around 205-208. I will be installing a trans cooler.
2007 Suburban 1500 5.3L transmission temperature with no load has reached 212 on highway in 90 degree weather. Stop & go traffic it hits 205. I just bought a cooler today I will be installing it asap!
What are your rpms @ when doing 75 and are you lifted on bigger tires. My 2010 is getting up to the 208 temp empty have 145k miles on it, im thinking i need a better cooler since i live close to the desert. So 90+ weather. Its a daily driver.
Big tires definitely make your temperature higher
Since lifting my Silverado mine stays 190-195
Have you installed a cooler yet? I just did the sure cool SL010 kit on my 2015 4.3 silverado and it hasn't gone over 175 yet. I read about people still running hot after the pill flip or surecool mod since we don't have an aux cooler like the v8s do. I want to add a trans cooler for preventive measure.
Dude 221f is not overheating a transmission. Especially if you are depending on the factory sensor which is normally in the valve body or post pump. Typically your trans pan temp is 10-25F lower as well. I wouldn’t even worry about the factory sensor location reading up to 235F+ and that’s still in the safe operating range.
Will a obd2 tell the real temp of the transmission?
I have a 2016 Tahoe did the tempo delete but when I’m driving temp 158 to 170 but when I’m in parking o on heavy traffic my temp goes its goes up to 230 any tips what could I do
Possible cause of your overheating issue.... U-haul box trailers are equipped with surge brakes. When you drive forward and step on your brake the weight of the trailer pushing against your hitch ball pushes a hydralic cylinder that turns on the trailer brakes. When you back up with the trailer, usually the brakes will not activateon level ground however when you back up on a grade the trailer brakes will drag. I have seen trailers with surge brakes lock up when a truck was backing a loaded trailer. With the trailer brakes dragging while backing up the torque converter in your truck will beat the transmission oil and heat it up fast, especially when there is little or no air going through the radiator which contains the transmission cooler. There is a lever on most surge brake systems that disables the piston that activates the surge brakes for the purpose of backing up the trailer. If you did disable the surge brakes before backing the trailer please disregard.
Enabran Tain oh work man, thanks for the info!! Definitely makes sense!! Never thought about it like this!!
He is right I pull those all the time. I had 5k in the trailer and when i backed in driveway with a small slop the brakes did lock up.
Replace the trans oil thermostat with the superior solutions part #STL010 and your temps will be in the 150,160 range.
Good recommendation ☝🏼☝🏼
My 2010 4.3 silverados transmission temp jumps from 170/190 to 277/244 but then goes down to 160, it just all over the place. I replaced the TCM, and had the transmission serviced.
It shifts fine, even before it was serviced, so no problems there, I get the warning "transmission hot idle engine" after 20 miles or so driving it..
Any ideas?
Thank you.
Im having the same issues and it overheats. No one has any answers!! Help
I had my transmission temp at 172 degrees Celsius. Which is 341.6 farenheit. Got the truck stuck on a lake going ice fishing. I didnt have the transmission fluid temp screen on when I was on the lake. So I didnt even know it was overheating. I looked down at my cluster and had a message. Transmission hot let engine idle. Took 25 min in negative 20 celcius to cool down. Had check engine light on and stabilatrack and traction control lights on for 1 day after this happened. Then it all shut off. Never had an issue since. Also I was in 4 low.
Bro Dup damn!! Haha glad it’s okay now man 🤙🏼🤙🏼
Mine did the same thing today. Warning chimes and flashes the engine in idle on screen you speak of. Unfortunately I was 2 hours away from home. Had to limp it home with noticable issue. Got home and added fluid. Started the truck up and it right a way climbed up to 200 degrees. So I shut it off. Now what?
Wow shit was probley boiling, the hottest I seen my trans temp get to in my ram was 215 degrees fahrenheit trying to pull a stump out of my yard in 4low
While plowing working the truck super hard I’ve gotten up to 240s 250. Truck was fine. I’ve since replaced the fluid with amsoil heavy duty trans fluid and did the thermostat bypass and it’s kept the temps way down. However if you live in a cold climate unless you use a fluid that can stay liquid at very cold temps like amsoil stays fluid up to -85f. If you use standard cheap fluid you’ll burn the trans up.
Shift technologies lower temp transmission thermostat! Regular driving mine stays around 145 towing the highest I've seen 175! The best part is there only like $38!!!
You received bad old advice. With DEXRON VI you are good. It's tested up to 260F before it starts to degrade. 220F would have been bad in 2005.
Yes I have flipped the thermostat and do the MOD ... it is super cool and I totally recommend it
Was your a 2014 chevy Silverado
Mine has went to 200 and also the engine stays at 210 degrees what's the problem with it
Joey Scott ... Mine is a Tahoe, it was reaching 200 F, but after the mod the range is between 160-180 F
@@3bd0o0l if I do the mod will it fix it and if at idle will it over heat both the engine and transmission
Joey Scott ... Will it fix what? Trans fluid temp? Yes, it will drop down. Engine temp is within that level you said (210) but at low load it can drop to 190-195 F (plug an OBD II to get the exact reading.
i have the opposite problem. i cant get my trans. to operating temp. i am not able to get it past 140F. thats not good , the operation temp. should be 170F - 185F.
No problem, 140 is plenty warm and won't hurt it
What about when it gets to 202 degrees
@@joeyscott9250 Intermittently hitting that temp every once in a while isn't that bad for synthetic fluid. However, running that hot continuously will degrade the fluid twice as fast as running a 180 would, and if the fluid breaks down and isn't changed, the transmission's longevity will suffer. Every 20 degrees you go over 180 cuts the fluid's life in half. If I was regularly seeing temps of 195+ and I wanted the maximum possible longevity out of the transmission I would install a cooler, but that's just me. Hope this helps!
I know this is an old video but the major problem is with chevy silverado is that the GM sends transmission fluid into a side tank of radiator that sits at 210° . This is a problem because this is normal temp for the coolant but transmission fluid doesnt like this. Heat will transfer from that radiator to the side tank. Heat goes to a cooler place. Best thing you can do is eliminate that and install a stand alone cooler like the Derale cooler with fan. They work awesome
Just got back from dealer. Thermal bypass valve faulty. Common issue . In and out within an hour…. Truck runs 190-200 now
How much did you pay ? Did you have OBD II codes ?
I have a 2011 Silverado 4.8 4x4
And I was at the drive thru at MCdonalds
And I saw it slowly climb from 198 degrees to 220 degrees in like 5 minutes🤔
Idk what happened, no abusive driving, not hauling anything. And trans fluid is still a pretty good color. Not dark
The warning doesn't even come on till 265F
4wd would not help. 4 wheel low will lower your gearing and help.
have a 2018. Plugged in my computer and showed up code u0101 . Pretty much lost communication with tranny control module ... Any help???
The transmission cooling lines go into the cooler in the radiator first, this actually heats the transmission, on my Chevy I eliminated the cooler in the radiator, I now have 2 transmission coolers in front of the radiator, both have electric fans run by a temp sensor for on at /l175 degrees off at /125 degrees.
Solved my issues
What brand coolers? Why two? Explain pls

So me pulling a camper of 6200 lbs in my 2019 chevy silverado 1500 z71 trail boss my transmission got up to like 270 and check engine came on they replaced the torque converter and something else now yesterday I towed the same camper and got to 250 but truck says u can haul up to 7000 lbs what is really going on and this was only a half hr drive
Yeah dude it’s wild. I ended up upgrading to a 3/4 ton diesel to be safe. Can’t understand either why they rate 1/2 ton trucks to 7-9k but they struggle with temps and whatnot. Now, I’ll pull 12-14k with my diesel and the trans never gets over 160 degrees!! Lol
I need help i engined swapped from 5.3 to 6.2 and the trans is over heating it has a 3600 torque converter what can I do
A few things one the thermostat on the side of transmission to these trucks have DOD and it causes the torque converter to slip need to turn off the DOD are you have torque converter failure which they’re known for because of the DOD
Got a question to ask? I have a 2012 Chevy Silverado 1500 lt 5.3 and the trans temp normally runs around 150 when driven normally but the recommended temp is supposed to be between 175 and 200 I had it up to 181 one time because I was driving aggressively! I don't understand how it don't reach a normal temp of 175 when driving normally but the stock trans Gage might be off to!
Gauge could be off, fluid could be a different viscosity than what’s recommended, or I’d say someone could’ve bypassed the thermostat keeping fluid running continuously to keep her more cool than stock if it’s preowned. Those would be my top guesses.
@@JohnWargo93 would that hurt the transmission not getting to recommend temperatures?
@@keepit100tho I know running it too hot will make the fluid lose it’s lubricants and that’s when you’ll start grinding gears. Lol

After driving my 2020 Silverado 1500 in the sand in NC, I noticed the trans was running around 230 in the sand but at 175 on the road. Iv been told this is nothing to worry about as long as I follow the recommendations fluid change intervals. As long as it doesn't stay hot in normal conditions, there's nothing to worry about.
How haw your Silverado Tranny been doing since this comment?
I’m in a similar situation
I always take my truck up to the lake with some steep inclines and my transmission temp is always around 190. Recently I went up to the lake again but this time I used tow/haul mode because I read it will be easier on the transmission. That day my transmission temp went up to 230 degrees.
Yikes!
Wow so much horrible advice with no real knowledge was given to you. Your torque converter slips when you are moving slowly and even worse in reverse with a load behind it. Reverse is geared at 3.064 vs 1st gear at 4.027 so it will cause more torque converter slip/heat to get the load moving. 221 is nothing to worry about but in the future just put it in 4low in these situations and you'll never have elevated temps since the torque converter will be spinning fast enough to lock. FYI your thermostat definitely doesn't know what direction your truck is moving, it strictly open and closes based off of temp.
Myles Hebert ahhh, thank you so much for the info man!! Very helpful!!
So the advice is to generate more heat with gearing it lower in 4wd?? An driving in 4wd at all times when hauling. Great advice, add trans cooler delete the inline thermostat, an if you have to change the tq to a better aftermarket one. Why generate more heat, in motor and trans am transfer case which higher rpms at all times in 4wd. These trucks tq is defective from the dealer an it’s hard to get them to replace it under warranty. Eventually the slipping is gonna send enough metal through your trans an trans pump causing major failure. Cooler thermostat an new tq on the after market side.

Converter lock up is controlled by the TCM, and never happens in reverse. It also pretty much never happens under a high throttle situation unless you have HPTuners or such and change the parameters. Best advice is to invest in HPTuners, Delete DoD/AFM, set 1-4 to never lock to save the converter, and only lock the TCC in 5-6 at low throttle. Bypass the cooler Tstat or invest in Superior Transmission part to set it to 135 if u live in cold environments, and install the LONG TRU_COOL 40k GWV LPD Transcooler. On my cammed 6.0 Denali I have the radiator bypassed also because it has a 3k Stall in it with a built 4l60e, my 14 Sierra has the stock converter and it daily driver so it goes thru the radiator also which warms it up fine in Southern cold weather. The weakness in the 6l80 is the converter from an OEM viewpoint, look at the TSBs.
Never had any issues with my 17 High Country 6.2L overheating but I changed/flushed the 8 speed to Amsoil ATF when it left the dealership took that OEM crap out.

Can anyone give me a hand? I bought a 2018 Silverado 4.3L 4 months ago with 40k on it. It was having bad issues when it goes in to 4 cylinder mode. So I talked to the head mechanic at my dealership and he told me to buy a chip that keeps it from going into 4 cylinder so I did. I’m driving it for the first time and I am 4 hours into an 8 hour drive and I noticed it stopped shifting while on the highway then I saw white smoke so I got off the highway. As I was parking the trans overheating warning light came on. Anyone? There is a fluid that went so that’s what I’m assuming the white smoke was from but there is plenty of trans and oil and coolant in the truck. Any help? Thanks.
Thank you for your helpful information, I am from Saudi Arabia and the weather here is extremely hot so you can imagine how the transmission temperature will be , two days back I bought a Ford F-150 v8 2019 (10 speeds) and I begin to experience some heating issue with my transmission reaching up to (222 F) ...I wonder if that’s normal or not ..I was driving gently in the desert with my air condition closed
Wasn’t hauling anything and reached 284°F today and the dealer I got it used from acted like it would be fine even though I know better and I wasn’t even hauling anything was just me and my wife and neither of us are built oversized lol

What is the transmission temperature should be at when it’s hot???
Man this video was about 4-5 years ago now… I honestly can’t remember what was typical with this truck. I know my current Cummins generally stays around 168 at normal operating temps.
My transmission temperature very low all the time.it that bad?after 4.5 hours straight driving from Vegas to new port California my transmission temperature was 178 degrees.when I just driving around town 120-130 degrees
Farid Gadimov you have the 6.2l?? I believe they do run colder by design with a factory built in trans cooler... the 5.3s don’t have that. The trans runs off the same piping our radiator does so they end up running a little warm all the time.
@@JohnWargo93 yes 6.2l v8 2017 Silverado.i have 2 exhaust videos.planing to do more videos.
Farid Gadimov I subbed man 🤘🏼🤘🏼
@@JohnWargo93 thank man.i did to 😉
I have a 2015 and pull a 34ft camper and the temp never has been higher then 195 even threw the hottest part of the summer
220* for a short time is no big deal. If it had stayed at 250 plus for a while is when it starts to break down. My 18 sierra 6.2 with the 8 speed trans has a heavy duty trans cooler that is built into the A/C condenser; yours may have one also. Go to the dealer give them your VIN and have them print out all your RPO codes so you know what your truck has.
jewllake appreciate the info man!! I’ll have to look into it
your rpo codes are printed on a tag that is attached to inside your glove box.
The new trucks actually just have a QR code you could scan and it will show you the RPO codes. Nothing in glove box anymore
Well damn... my ‘15 Silverado (company truck) digital readout for my transmission was at 284° the other day hauling a bed full of tools/materials up a mountain.. after reading these comments I’m going to have it checked out and serviced. Once I switched over to “manual” and selected the gears individually and activated the tow/haul feature it dropped back to 220°ish. Will see what the mechanic finds... fortunately I won’t have to pay for repairs, I’d never abuse a company vehicle, but I try to have it serviced when needed. Thx
The radiator was low on antifreeze, and there apparently was a very small birds nest covering the radiator. I was told if the radiator is low on juice, the transmission overheats BEFORE the trucks temp overheats. If you’re running into a similar issue then check your antifreeze/coolant levels!!!
Frank Leathers how low was it?
Ismael Perez i don’t know how low the antifreeze was... by that point it was in the shop. But the mechanic explained that the way those trucks were designed when the radiator was low the transmission would heat up first, then the motor. Kind of weird
Frank Leathers ok thanks bud
I have a Chevy suburban 2013 and the transmission fluid goes up to 205F.. that’s normal? Help please.. thanks!
Nestor M Palaquibay 205 isn’t going to hurt anything, mine does it often while cruising big hills and occasionally in 4x4. Wouldn’t let it get up over 230ish though
Thank You John
No that's not good, operation temperature is around 140 on a cold day driving 160-180 driving on warm day
You think the mishimoto transmission colors will help with or without towing?..
l Pronox I’m thinking so.. anything that’ll get cooler fluid through the trans should be a big help!
Yes that’s what they are made for , 10 row or 25 row doesn’t matter it’s just a extra external cooler .
Did mishimoto transmission install without the bypass valve delete and was getting same temps driving on the highway with 95 degrees outside.. was getting 180 and went up to 199 without tow. Consider doing the bypass valve delete but here in Central time zone it gets cold.
Cover the exhaust baking the trans pan and the trans lines going by the catalytic converter. A cool trans is better than a burnt one. Do the thermostat mod, the cash will stay in your your wallet.
What’s the thermostat mod?
Good video man.
What is the recommended temperature on the transmission what's the temperature range with out pulling anything??
Mine typically floats around 185-195 normal driving
@@JohnWargo93 I noticed mine at 192 195
John wargo do you know what kind of fluid is required for a Differential flush on a Chevrolet Silverado
@@arturo2637 nahh I’m not too sure without opening up the manual to check
I have a 2017 Chevrolet Silverado 2WD just about to hit 100K mi trip to Arizona my truck slipped gears and then over heat + 220 transmission fluid’ I added fluid and towed now it went down but should I delete thermostat ? It should work to cool down lines I’m hearing?!
Great video describing similar situations
Yeah man I hear that bypassing that thermostat does wonders!!
When the car is on Park "P" why transmission temperature dont decrease is still keep the same high temperature. My car is F150
That's a truck lol
just bypass rad oem cooler and use external one
That's not hot. Not even close. Synthetic trans fluid is good to 275°. I've had mine up to 240° with no issues. If you tow occasionally, don't even worry about it. If you tow heavy and often. Then adding an auxiliary cooler and doing fluid changes periodically and your golden. But your worrying about nothing.
You were backing up a trailer with surge brakes up a steep hill. You were fighting the trailer brakes.
Duuuuude made this video well over a year ago and not a single person made that realization! That makes total sense now! Was a bitch to get up there! Haha
If it has the correct trailer wiring, the back up light circuit should disengage the brake system.
@@Resistculturaldecline not with surge brakes.
@@mikep780 Then there should be a pin or bracket to prevent the rearward movement of the tongue assembly. At at any rate, it's avoidable in the future
@@Resistculturaldecline yes its called electric brakes...
Had my transmission fluid get to 252 degrees on my 14 z71. I was about 3 hours into a pretty challenging off-road trail in Colorado when I checked and saw it was at 252, immediately shut the truck off and let it cool for 30 min. I haven’t noticed anything weird with the transmission after that but I will be doing the thermostat mod soon
Dalton Vetter damn dude! Glad it seems alright now, but yeah... gonna have to do the thermostat mod myself I’m thinking!!
What is a thermostat mod? Is it a "thermostat delete" as some people are saying? If so, how will that hell the temperature of the transmission? Thanks!
They should be a recall in these Silverado transmissions. This is absolutely ridiculous for these transmissions to only last 120-160 miles
What was that Facebook page you mentioned?
5Th Gen Silverado and Sierras
What mileage do you change fluid?
I do mine every 50k miles and still comes out nice and red. Some color in the filter that it is working and picking up clutch material. 60 is ok still.
@@joaquinaguilar5942 Which fluid brand do you use. Is anyone better to keep trans cooler.
221 technically isn't overheating for that truck.
Do the needful trans thermostat delete mod . Simple .
How ?
Trolling hard 😂
I took my 14 Silverado to GM about my transmission slipping between 2nd and 3rd gear they told me they just got a bulletin from GM they know about the issue they told me to put it in reverse before I put it in Drive to purge the air out of the transmission does anybody else know about this issue
i have a slipping in my 2011 silverado from 3rd to 4th. where can you look up those bulletins ?
Transmission delete is cool until you run it idle without ac on in drive, watch those numbers go way past 190. Keep truck moving and you are good
my 2009 silverado, i pull 2 tons on a 16ft trailer, the temp goes up to and sometimes maintains 230f even 240. its been like that for years . is that bad?
Rob Calton should probably take a look at the transmission fluid and see what temp it’s rated for before losing its lubrication abilities.. a lot of ppl tell me to change it out if I ever come close to hitting 250 degrees
John Wargo thanks ✊🏻
You should be fine. Newer fluid is rated to 260. If you had a 2005 or older truck, then it might be an issue
My 2014 z71 blew my trans on a trip back from Florida to Houston it was jerking hard but it got me home 147k miles 300 more and the warranty wouldn't have covered 3k out of the 5k repair they put a "new" one it is very shiny
rafa baraja how did you get the dealer to cover your transmission at 147k miles ?
@@garciae2571 i did pay out of pocket to get the ac condenser and compressor for 900
That’s crazy high. I replaced my condenser for about 300$. About to replace my blown transmission with motor for a lower mileage one for under 2k
Reason I stay away from dealerships
@@garciae2571 it was an "assigned" i coulnt really get picki about it either way i dont have 50k for a brand new z71
+1 on the 4x4, been told always use 4x4 when backing up a load
Jake Steiner well at least I know now 😂😂
Good luck turning ur wheels on 4x4
What’s the transmission fluid temp should be at ? Normal drive ?
victor alvarez it normally fluctuates between 192-196 during daily driving conditions.
@@JohnWargo93 yes anytime your transmission fluid gets over 200 degrees it depletes the life of your transmission , it might not get 50000 miles out of it
Turn the music down cants hardly hear you
Cool vid bud. Never had that happen in reverse towing, so I never thought about that one, but mine had run hot since the day I drove her home. Did the t-stat mod myself a few years ago and ran duel coolers. 2014 Rocky Ridge(over priced ball and chain) Shakerado 5.3l This truck still had the original 3.42 gears in with a 6" lift, 35's on 20's and on it's 3rd torque converter when I finally made a few changes to GM's "brilliant"(insert sarcasm here) engineering. Has run low 120's cruising interstate for hours on end(weekly 5 hour commute) since except for a few abnormally scorching summer days got up to low 130's. You may not need duel coolers depending on tire size, gears(overall strain on driveline), but if you go that route make sure to run them in parallel with each other, otherwise the effects of the pressure drop will eventually show their ugly face in the pump(scouring) and TC. A couple manually switched or temp controlled fans for stop and go and a manifold with a manual bypass ain't a bad idea either. Had to make up a manifold winter before last since trans wouldn't get any hotter than 100.. Hope this is helpful. Apologies for writing a book. Fingers just won't quit adding shit.. lol
Zack Thomas hey man, thank you for the info for real!! It’s crazy how these trucks leave the factory with so many quirks. Lol
What’s the name of the Silverado group?
John Short it’s called “Gen 5 6.2 & 5.3 Engine Sierra/Silverado (2014+)”
Awesome thanks. Good vids man. Did your same motofab lift on my 16 LT just went AT 285 tires instead of 33s because I tow alot
John Short thank you sir! I might go a little smaller soon myself, trying to start hot shotting cars and equipment. These 33x12.50s are a little uneasy for towing I think. Lol
Good lookin out
Whats the name for the FB page?
gimmpy91 facebook.com/groups/508636975945052/?ref=share
my 2016 silverado is heating up to 270 - no lights or issues happening but I am bringing it to the dealer to look at it. I also have an extra trans cooler
If you would have just got to the point I'd have watched to the end.
You’ll have that 🤷🏻♀️
You need a transmission fan
You need to edit this shit
Pull over and let it cool down .
You didn't share anything new other than your towing trip caused your transmission temp to rise in two different occasions, I thought you had done your research with important transmission video info. I clicked on your video thinking you were going to describe normal operating temp vs. maximum allowed operating temp and how to prevent it / when to get your transmission checked.
Nope! 🤷🏻♀️
