I have the misimoto kit with the bigger trans cooler. I average 150 in west Texas with a large cam. This is a must do modification.
where did you get it?
I have a 2015 Chevrolet Silverado V6 4.3 and I was told that my torque converter was going out I was told to get a heavy duty torque converter what do you recommend. And how can I tell if my torque converter is giving out I took it to 4 different places and two said I need to replace the transmission another place said it was the torque converter and another place said it's a solid transmission all I need was to do a filter change and fuilds.
How many miles on it? The torque converters are known to go out after about 75,000-85,000 miles, some are lucky and they go 150,000+ with no issues. But if you have that many miles on it, and you have the means to replace it, I would. Cause if the torque converter goes, you’ll end up having to replace the whole transmission.
All your videos are excellent. I watch and like all of them. I used the kit on my truck and had the same results . Thank you
Did this to mine and it still averages 185-210°f I think the torque converter was already too far gone, it failed at 99k miles. Looking to get a billet torque converter for it now
does sound like a failing Torque Converter my suggestion would to be to look for a Billit Torque Converter
@@codemansauto208 I am on the market for one, I been looking for the past couple days, do you have any recommendations on them? Like specific brand or part number or anything, even a lead in the right direction would be helpful haha
the 2016 chevy torgue converter are bad get a billet converter
I used the Sure Cool, part #STL010 .... $45
me too
I have a 2017 Yukon with 41000 miles, and I am having the torque converter changed out and replaced with a billet converter and some other modifications recommended by the very trusted and knowledgeable transmission shop owner. While doing the converter swap, he is going to install the Superior STL010, 6L80E / 6L90E Sure Cool Thermal Bypass Kit. All this work being done is proactive on my part to make sure my 6L80E transmission lasts the life of the Yukon. My plan from now on is to do a pan drop and replace trans fluid and filter every 35000 miles. I did a pan drop and filter change on this vehicle at the 39000-mile mark and the fluid was in excellent condition. A full rebuild is not cheap and in some cases a defective factory torque converter does so much damage the transmission is no longer reuseable, and a new or remanufactured transmission is required. I don't want to go down that very expensive road in the future so that is the reason why I am having the billet converter installed and the other recommended modifications done now. The factory thermostat runs to hot, and it is advisable like this video shows to replace with a lower aftermarket thermostat. Thanks for the informative video.
Would you recommend for someone who lives were it gets cold like Wisconsin?
I bought used 2017 Chevy Silverado 1500 with 46,000 miles about a year ago and immediately deleted the afm and installed the transmission cooler bypass as well as changed all fluids front to rear! Hopefully I'll get many a mile before any serious issues! My transmission temp is almost always at 145 after the fact and the highest I've ever seen since is 170 but goes back down after climbing a hill while towing
What part did you install for the AFM delete?
@@singhbling5190 range technologies afm delete module. Simple, just plugs into your OBD2 port
Sorry I just had seen your comment, I used range technologies afm delete module. Been over a year now and never an issue even after sitting in the garage for over a week my battery has never went dead. The only issue I ever heard complaints about the module.
I put the transmission cooler delete on a 2021 Chevy Silverado and I live in Cincinnati Ohio and it got down into single digits and I just let it warm up every morning and it was fine
During the summer and hits about 145 from a cold
Start
2014 all the way up to current you should do it
I had a video made when it was 17 below zero and my video got destroyed but yes it took less then 10 minutes to get the transmission up to 60 degrees with the delete installed I couldn't ask for it to work any better besides what people don't understand is from 2008 to 2013 this same transmission without a transmission thermostat had a lot less problems with the same torque converter
My brothers runs 140 through the hills of West Virginia mine runs 185 5miles down the road and back definitely gettin the bypass upgrade
Would that help my 2020 Silverado 2500hd with l8t gas and six speed transmission? Thanks
I did this on my 2020 Ram 3500 6.7, i hit 132 with empty trailer, loaded with 30k lbs same to 155. Highly recommend.
I did this but now it ran 202 degrees and then the next time it was 168 degrees 🤦♂️
This is not as good as the $60 Shift Technology kit. Mine will run at 140 to 170.
What
This is a must do upgrade, The manufactures only want higher temps for epa emission testing, people always argue "Ford says they are fine to run at 210" ya well Ford also says do not change fluid unti 150k miles
my temperature on my 2017 Silverado goes to about 150-151 but that’s it
The transmission sends fluid first to the cooler in the radiator, so the coolant runs at 195 degree, the second cooler is not sufficient to help.
On my truck I eliminated my lines to the radiator, I now use 2 external coolers with fan's, the sensor I use turns the fan's on at 180 off at 165, I also have it wired to my A/C. When my account clutch engages the fan's come on. 93 degrees day my 6L90 has never gone over 165 degrees
@ what temperature does condensation evaporate out of your fluid ??????????
Might as well install an ice box and heat exchanger guys you need the fluid to get hot enough to get the water out of it. Same with motor oil you don't want to see what oil does to an engine that's kept to cool.
Looks like your converter is going out
I have a 2015, 2500 Silverado 6L90 transmission I’ve never ever seen it rarely over 150 151° and that was on a 95, 100° day most of the time it’s between 128 and 131°
Is that bad for the truck? That’s what’s mine at on my 1500
Transmission is a pos. Gm should be ashamed
Has anyone found that using trans fluid like valvoline or a/c delco any better to keep trans cooler,or amsoil?
I did the pill flip on mine, went from high 190's to not over 150 on the highway. 170's in town.
I have another video on why I dont like to flip the pill please check it out
Next, please do a video of the install of this part That would be great
I don’t understand why he didn’t show that in the first place
The link to the Transgo kit is in the description. The scope of this video, I believe, is the before and after comparison. I'd imagine there's other videos out there on how to install it.
Scroll down another video and he does have instructions
It’s super easy 2 bolts
I live in ny..winters get pretty cold how can this not make it run too cold in harsh winters? I feel like it’d make it so it’d never get close to a somewhat good temp. Please advise. Have a 15 Silverado. Average temp is 185
With the delete and a tune I never get above 150, deleted AFM and changed the lockup from 14 mph to 25mph. No 4cyl bullshit all this was done because my 6L80e ate shit right at the same miles as this dudes truck
How do you get a tune ?
Mine keeps getting hot slowly and I’ve reached 250 which is extremely bad. If this bypass only drops 20 degrees, will the even work for me?
if your thermostat is going bad then it is going to drop it a lot more then 20 degrees hope this helps
Dude my fucking 6l80 hit 227°f climbing a mountain yesterday unloaded and I wasn’t even going fast. I pulled over and shut it off this is a 2019 this is some bs lol
i have a 2016 yukon xl 5.3 and a 2014 chevy silverado 1500 crew cab 5.3 how doni figure out what transmission i have?
Is there any danger in the trans being too cool, for those in cold climates in winter? I mean, the results speak for themselves here but there has to be a reason GM put this on these, right?
GM started installing these on the 2013 and up because they wanted the torque converter coming on at around 10mph the torque converter apply works better with the transmission warm but these temp thermostats are running to hot for factory converters but just to let you know GM does sell a 155 degree thermostat for these trucks just in case you wanted to stay with factory parts I hope this helps you
@codemansauto208 Yes, thank you!
@@codemansauto208 I've been watching my transmission temp gauge on my dash since watching this video, and while I only make a short 6 mile drive into work (lucky, I know), it hasn't gotten above about 133 when in the 80s outside. I'm going to keep an eye on it during longer trips and see if I need to take action. Thanks again.
@@AimingWanderouslysomeone may of already changed yours
@@slalomking I suppose it's possible. I bought my '16 when it was 3 yrs old. It heats up quick though, but it's summer, I'll keep watching it now that I know to.
Man my 2023 Chevy Colorado transmission temp is 205
3.0L duramax?
Does this also affect the Tahoe? I have a 2018 Tahoe, no issues but was thinking of using the Superior brand version kit if this will work for the Tahoe.
I think so. I used the Superior kit on my '14 Sierra and haven't seen anything over 153° since.
What the temperature it should be at
I have a 2011 Chevy Tahoe transmission overheating 190 to 200 any answer
sometimes when the converters start to fail they can cause the transmission to overheat and just to let you know if you change your converter you should back flush from top to bottom on your transmission cooler inside the radiator these tend to stop up and reduce the fluid flow
I have 16 and want to do the same. But have a question for you. My fans stay running while driving I changed my temp sensor and thermostat and they still run Any answer
if your cooling fans are running it may be because your air conditioner is on the electronic cooling fans are designed to run with the AC on for your condenser as well as your engine I hope this helps
A complete bypass is a bad idea IMHO as the TBP bring the trans temp up quickly for better operation and regulates it at a lower temp ... Installing the GMC upgrade mod TBP will keep the temps at 150*s city to 160*s/70*s Hwy ...On hot summer days in stopped traffic its gone up to 180*s+ but comes right down when moving again ... Just remember that ATF best operating temp is 175* ... :)
Reply
I installed this on my 2014 with 6L80. Temps went way down. I replaced my thermostat because it was stuck open. did a coolant flush, now my trans temp has jumped back to 190 - 200 on hot day.
I’m is 220
I just changed mine in a 2018 suburban. My tran temp got up to 225 and went down to 174.
The install is super easy. Mine dropped from 190 to running 140-150. Dont know how that will go in the winter but the fluid was black as coal and that definitely isn't good
I put the bypass on mine and it's still running hot, any ideas? Before anyone asks, yes it is installed correctly, hard to mess that up. Thanks in advance
Mine must already have the bypass delete. My 2016 2500hd stays around 145 always on the highway. Even towing 12000 on a 90* day.
Ive seen 170ish sitting in stop and go traffic before and thats about it.
I have the same issue with my 2008 Cadillac Escalade it goes from 180-195 really fast been having the same problem thinking it was the coolant lines switched them. Even switched to heavy duty stall and was thinking into installing a bigger transmission cooler
I have a 2012 silverado with a 6L80 transmission. Will the cooler delete work on it?
the exhaust pipe 2 inches under the pan is a big problem iam thinking about putting some one inch thick chimney insulation arond that pipe its rated to 2500 degres just working on how to atach it .maybe some refactory cement.
How bad is it my 2021 stays at 195 when hauling a trailer and 190 normal
Let's see how it does it stop and go traffic that's when they eat up
I can drive for a hour and can't hardly get my 6l80 transmission to 120 degrees. I want to conduct a relearn because I have no codes but I get a flare if I'm going very slow and the truck is cold. No problems if I accelerated quickly or if the truck is warm.
so let me respond to the part about subzero weather in the video… I have this installed in my truck 2014.. no issues no complaints. It works fine. if it’s 30 or 40° out and I’m cruising on the highway I might hit 150 but usually in the 140s… OK probably fine with that.. as I go into Northern Maine, if it’s -10 or even zero outside my temperature runs about 100 to 115° degrees. The outside temperature seems to dictate a lot of how the surecool works in my truck. if I travel at lower speeds, it warms up a bit if I go faster it cools down. but outside Temperature plays a huge part.
It’s a great product it does what it says for the most part. I’m just not sure if I like my transmission running at 100° when it’s subzero sometimes it doesn’t even hit 90 if it’s below zero. Unless somebody can tell me that it doesn’t matter.
Mine does the same. past 3 winters mine will get up to 90 or 113. about a 15 minute drive to work. stop and go traffic.
@@carbonsteelbladetheorigina7993 so you’ve been running it for three years at least. And no issues right with it running “too cold”.
@fishman80 None at all. trans temp in the morning are 40 or 50 at startup. I give it about 5 minutes and I'm gone.
@@carbonsteelbladetheorigina7993 awesome thanks. we pretty much get all four seasons here so I’m pretty familiar with the temperatures you get versus the ambient temperature outside. so it’s good to know about the cold temperatures where you live and experience you havent had problems. I got a 2014 so just trying to prolong that six speed lol
That temp reading on the gauge is calculated, that’s not a sensor reading. The sensor in the TCM is for the TCM’s protection and does not report to the IPC
This is only for the 5.3 NOT the 4.3!!!
do you still prefer the sure cool?
I have not seen any difference in the sure cool or the delete only in PRICE
What is the name of the part. Also, where can I get one.
I have a 2016 2500. The temp never gets that high unless I have been towing my camper for a couple of hours in 95 degree heat.
Edit... I actually just heard about this "upgrade" from a guy I know. I wanted to monitor my temps on 4 hours trip. The temp never went over 125 degrees without towing in 20 to 30 degree winter weather. I will continue to observe.
2500 HD did not come equipped with a thermostat for some reason, I have not done any that has had a thermostat

My 2007 Suburban hit 226 over a pass and 190 pulling a 4000 lb trailer in the winter on a 3000 mile trip, have i damaged the Transmission?
Probably not.
How much does that part cost and labor
i put the 50 doller one off ebay with the ball bearing in it cant think of the name of it but most people recomended it. easy instal took it out abot 25 miles temp today was 85 the temp got up to 150 i dont know what it will do on the hwy i was on the back roads of tn lots of hills never got over 55 but big inprovement.
Sure Cool. Part. STL010
Have you done the 2022 10 speeds yet?
Is it supposed to drop your temps while youre at a red light on stuck in traffic? Mine seems to run hotter now after i changed the filter. Maybe bent one of the cooler lines?
No .. The temp will rise a little while at a redlight or stuck in traffic ... The GMC upgrade mod TBP will keep the temps at 150*s city to 170*s Hwy ...On hot summer days in stopped traffic it's gone up 180*s+ but comes down right when moving again ... Just remember that ATF best operating temp is 175* ... :)
What delete did you do?
Where can I buy the piece?
I want my fluid to run 190* Its just me
Please let me know if you ever have transmission failure, I would like to know thank you
The gm tsb. Was issued specifically to avoid 195. Why would you want to run hot? Tsb was to correct a failure. The delete is better. As t-Stat is a fail point.
How do you do a cooler delete
Well I had bought a 2016 suburban with 84000 miles from a dealer had the transmission fluid and filter changed immediately. I had seen the transmission issues being posted. I do drive quite a bit of 3-6 hr trips in general and this new truck I noticed the transmission temp go to 194 in 30 degrees temperature and seen your video and immediately did the switch and temps dropped while on hwy to 120.
But oddly enough today I did a 5 hr ride on pkwy and had got stuck in traffic halfway through and sat in car for 39 minutes and tranny temp went right up to 182 before traffic eased up and got to highway speeds.
Now todays temps were 50 when driving
This does worry me when temps get higher and I do drive this
Ever. With new stat
Hey, I just installed this on my 2019 suburban. Had it installed for about 3 days now. The first day was great, temps dropped down to 150-160ish and about 140 on the freeway. But yesterday I noticed it was getting back up to 190 on the street and about 165 on the freeway. Do you think that’s normal this this part installed or should it be way lower?
Transmission failure starts to happen at around 240 degrees F so you have to realize that your cooler is running through your engine coolant which should be around 210 degrees so if your transmission doesnt go above the 210 for long periods of time then you should be just fine the thermostat that you deleted holds the transmission at 195 degrees and never allows it to cool down and that destroys your fluid
My 14 Silverado got to 198 and the longer I drove it the hotter it got. It got hotter after getting off the expressway. I have seen it climb to 214 and a long time to cool down.
I have a 20017 Silverado z71 crew cab and I just installed a week ago a new rebuild transmission 6L80 with a lot of billet parts and billet converter all the updates from Sonnax. And still I had to take it back and replace the new defective oil pump it was making loud noises in the 4-5-6 gears and overheating up to 210+. I just got it back noise is gone thats good news but the bad still overheating i have the same problem keeps going up to 214 hot and I’m not even pulling anything yet. and it will probably go higher but i don’t let it. I have to stop and pull over let it cool down before driving it again. I just order the mishimoto trans coolant kit. I have a bypass already installed and still gets hot. So I’m gonna install it this weekend we’ll see if it helps. I’ll update once is completed and tested.
@@arkangel2351Damn are you a time traveler?
Thanks, for the video. The GM design has the exhaust right up against the trans pan, this is a poor design. I’ve had one of these kits (not this particular one) put in and still get up to 250 degrees when pushing the truck up elevation. I would love to get this fix for good…
Will this work if you have the 4.3 V6 engine?......I've read that it won't help with the V6 engine.
no it wont, sorry for the late reply
yes it will. the trans are the same@@codemansauto208
@@codemansauto208whats a good way to get somewhat lower temps?
I ordered one off amazon be putting in asap

I was always at 194 and last sunday it blew up. I rebuilt the transmission and also installed a thermostat kit and finished last night. My temp never got above 133 coming home last night. Its like 40 degrees outside so I expect it will eventually get hotter as ambient temps rise.
GM has an update for this: TSB is 21-NA-199 new TCV opens at 158 degrees and takes less than 15 minutes to swap it. Part is $58. Better than some silly "delete".
why would I install a part that could go bad when i can install a part that will never go bad, convenient for GM to possibly sell a million of these and make another 58 million dollars off the consumer no thanks i will stick with my cheap delete
@@codemansauto208 A bad thermostat was one of my concerns. Why run the risk. My truck runs 130 to 145 approximately. Backing a camper into a stal, raises the temp really quick.
No, it's not better. Same part will most likely do the same thing. The delete doesn't hurt anything. It's exactly how transmissions have been run for decades, with zero issues.
But go ahead and waste your money over and over again. All you'll prove is that you're not very smart. 😅
30° shave off is great 😎🤙🏻
195? Mine gets 220 before i pull over and let it cool off
That is way to hot and needs to be repaired pretty soon or could cause damage to the transmission

If you live in a heavy salt state like I do in NY. It can be VERY hard to get the clip out. Buy some CLR and let it sit on top of the housing after you take it off. It worked AMAZING for me.
This video while factually true is misleading.
1) The trans thermostat bypass valve (TBV) purpose is to reach optimum operating temperature quickly in all seasons, increasing load handling and fuel economy.
2) The stock GM TBV on the 6L80E used to open at 194°F(90°C) but they released a TSB. Talk to your dealership and they will replace it with a 154°F(70°C) one for free.
3) Closing the bypass doesn’t increase the efficiency of your trans cooler, meaning if you hit 220°F in town, you will still hit 220°F in town it just takes more time to get there.
4) The trans cooler doesn’t go through the radiator. If you look at your lines you will realize it has a separate cooler as part of the AC condenser in front of the radiator.
5) If you live in a cold climate, expect to lose slight MPG with the bypass delete mod because the trans will take a long time to reach operating temperature.
6) I installed the Shift Technology STL010 kit and drove up into the colorado mountains and it still hit 250°F before I let it cool off. Without it, it would have hit the same temperature only quicker. So, the point here is that sometimes you need a bigger cooler, and with a bigger cooler you probably want a thermostat! Because closing the bypass would make it even harder to reach operational temperature.
7) If you only do highway or short trips and don’t tow and don’t off-road then a closed bypass mod will give you lower temps because the rate of temperature rise is lower, and it removes the temperature floor of the system.
Anyways, so that’s what I’m doing, ordered a bigger cooler, and will put the 70°F TBV back in. I’ll have a quick warm up and a much shallower angle of temperature rise vs load.
Would have been useful to show the install. Without that, thi9s is actually pretty useless.
If you can't figure out how to swap it out, then you really shouldn't be working on anything at all. It's not rocket science. It's two small bolts. 😮😊
@@icefisher1171 Fair point. I concede.
GM indicates ideal temp is 180-200f. Below 170 is bad, you want it to get to operating temp as quickly as possible. Honestly I do not understand this mod and will not do it u less I see temps creep above 200 on a regular basis. Towing 6k boat I’ve never seen my trans temps go over 200, stock 2015 Yukon XL 5.3.
