- This applies to 2014-2019 Silverados with a 6L80 transmission, however it is always a good idea to install an updated thermal bypass or a transmission fluid cooler no matter what truck you have. Link to part below:

When I found out about this I immediately went to the steelership and got the updated version , I noticed a huge drop in temp from 195 to maybe 165 , it works and is worth every penny .
How much did the updated GM thermostat from the dealership cost?
@@StrongTurf 131 .00 including tax
Should I go for GM updated version or PPE brand ….
@@JuanCoreas-nf3wq yes
@@chowhound33ify yes what lol
A MUST DO upgrade to a Silverado. My 21 had 4 miles on it when purchased and started paying attention to trans temps after watching simular videos and didn't like what I saw. Immediately installed the Superior kit and temps reduced dramatically. We pulled a 6x12 inclosed U-hall from NC to Daytona with two motorcycles in upper 80 degree weather at 65-70 mph and trans ran 130-150. Big difference!
FYI you can tell if yours is the updated factory version. Look at the bottom of the TBV @ 8:40 in video. It will have "70" stamped into it. If it has the stamp that means they replaced the old one and your g2g!
Changing out the original TBVs on these transmissions is a must if you want them to last.
Yup I have no idea what GM was thinking when they made the stock TBV to only open at 195°. Absolutely cooked my 6L80 and it blew up on me at 150k miles
Planned obsolescence @@StrongTurf
I have the 2021 Custom Trail Boss. I put in a Superior Solutions transmission thermostat delete kit in it and swapped the stock trans cooler for a 40K and added two more quarts of oil and it made a big difference in my transmission temperature. Previously, it climbed above 200 at night pulling my boat at night up The Baker Grade outside of Baker, CA with the AC Running so I decided that wasn’t ever going to happen again so I did the above. If I’m still not happy with my transmission temperature I am going to add a thermostatic fan to the cooler.
Nah, Dude, you're absolutely right about those crazy High Temps. I strongly recommend you consider wrapping your Exhaust pipe that's traveling Directly under your TranPan with some Titanium Twill Weave Exhaust Shield Wrap (2"X50ft)
That Pipe is just WAY Too Damn Close and it's literally Cooking that Transmission Oil!
Wrapping the exhaust that crosses under the trans pan is excessive and unneeded, and pretty ineffective at reducing the fluid temp. If you want to reduce the temps the best way is an aftermarket trans cooler.
I have a 2012 with the same 6 speed transmission but GM didn’t put a crappy thermostat on them and even towing my boat down the highway on 90°+ days my trans temp stays below 170° and might climb to 187° in stop and go traffic in the city.
@chevyon37s Actually, by wrapping my Exhaust, it reduced my Temps by 15 degrees.
"Uneeded" ... maybe
"Ineffective"... Most certainly NOT.
I agree, however, on the Thermostat issue.
A 160° Thermo wouldn't allow for proper Running Temps ... therefore, you would never achieve the Running Temperatures required to get the vehicle to operate as actually intended.
But a 180° Thermostat WOULD DEFINETLY be an Optimal Choice to help keep those insane Temperatures DOWN and still maintain Proper operating functionality within the vehicle.
But, Dude... Don't Knock it until you, at least, TRY it. That Titanium Twill Weave was Just What the Doctor Ordered! Fifteen Degrees is still FIFTEEN DEGREES.... No matter which way you wanna try and slice it, Turkey.
My 2017 3500hd has no trans thermostat stock. I added coolers and now stays under 170 towing and 145 normal driving. Great truck!
Must be nice, shit I put the thermostat bypass in mine so it’s basically deleted, and my transmission will still hit 215°f in stop and go traffic not towing lol
I did the same thing, bought the updated GM one, then got the PPE one and also the deep pan they make to hold more fluid trans runs nice and cool. Did notice that in the cold weather here in NY trans temp does not get very high and gets very poor gas mileage in the winter.
What the difference in gas mileage and why you think it causes drop in mpg I know tire pressure drops couple psi in cold
It's know fact for any vehicle in Northeast to get worse mpgs in winter due to running vehicles at idle longer and the gas mixture is different from the summer mixtures due to the temps
I put the same thing in my 2015 Silverado about 2 months ago, temps went from 190-200 to around 150-160, easy install. I was going to use the superior solutions install kit, but could not get the piece to come out after removing the snap ring, I tried everything short of drilling out the center and probably ruining the whole device. So keep that in mind if you plan to replace the bypass yourself.
I have a 2017 Sierra. I just changed mine yesterday! Temps are at least 20deg cooler...
Soaked the original tbv with some wd 40 and my 8 yo son took apart the original with really thin needle nose pliers and a pair of regular pliers and he rebuilt the original block with the superior solutions bypass and re assembled it while I just put the newer tbv block from the dealer for 100 bucks and changed the metal gasket behind it that’s recommended and now I have a backup if I don’t like the newer gm bypass valve I wanted to make sure I had options being the truck only has 27k
I’ve heard the WD40 works for some people and doesn’t work for others. Mine looked like it would probably be easy enough to open up, but I figured I would just not bother.
Bought a used 2016 5.3 with 70k miles. At 90k miles my tranny started to shutter after a long distance drive in hot weather one day. Swapped out atf fluid and filter along with this mod and haven’t had any issues since now I’m at 105k miles a lot of towing my boat
Oh yeah the famous Chevy Shudder. A friend of mine is dealing with the same right now on a 2017 Silverado
@@StrongTurfremove transmission pan and change filter. Install superior transmission cooler valve. Replace fluid with mobile one lv synthetic transmission fluid. It's the blue lable fluid. You should drain out around five and a half quarts, when removing pan. I changed mine twice before dropping pan and changing filter. Runs around 147 degrees, and no more shutter. Resetting the transmission is a must. I used Vident scan tool for resetting transmission. All the new 6,8,10 speed transmissions from all manufacturers have the shudders.
I change that thermostat in a 2018 Sierra 5.3 the temperature in the 180s now that I changed it it runs about 158 glad I changed it
The 5.3 is know for dropping lifters and it's not a cheap fix ..They say it's not if, it's when they go..
You can order a chip you simply plug into you obdll to keep it in the v8 mode and keep it out of the v4 mode ..The problem lies in the vlom below the intake...
To replace a lifter you need to tear the top of engine down to just the block ..With them engines you just can't remove the intake to replace lifters ..You need to also remove the vlom and heads ..Then if your lucky the cam is not destroyed..
The chip can be bought on Amazon for $200-$250...
I can’t believe your transmission builder didn’t do this when he rebuilt it…
Shop I took my last truck to, and my buddy took his 2015 to for rebuild won’t rebuild a 6L80e without doing a thermostat delete and a billet torque converter. I’m at 157k miles on the 6L80e in my 2012, BUT I do have aftermarket trans tuning and I do change the fluid regularly-ish.
I did not have it rebuilt, I swapped the transmission myself for a remanufactured unit and then did the thermal bypass after
@@StrongTurf ahh that makes sense
My 2018 Silverado 1500 transmission blew at 110,000 miles. Got a "new" transmission and after a month was seeing trans temps still above 220deg. Installed the Superior Solutions kit you referenced, and temps have not gone over 195deg since installed. Had Chevy dealership look at transmission for high temps twice before it blew and all they did was replace the transmission fluid.
Oh jeez. Yeah 220 is not good at all. The most I’ve seen on mine is 207 and I think even that is way too hot
Mine goes all the way to 260. Its that mormal?
@@SerafinN26 no 260 is bad. You are cooking the internals of your transmission if you drive with those temps
Listen thank you from Jorge Garcia Dallas Texas
Bro get to the point.
I used the superior kit had no issues taking it apart, Trans runs at about 160 towing like my older trucks did before this stupid thermostat
I’ve heard good things about the Superior kit. Although my TPV looked like it would be a huge pain to open up. Plus I didn’t have any snap ring pliers handy
I changed it on 2024 Silverado temp never goes over 175 degrees
My 2020 AT4 trans temp has never gone past 160. Just changed the trans fluid at 95K with amsoi
Great Video Thank you.Will this work on the 8L90 Transmission? " 8 speed" 2017 Silverado..
Prior to your transmission blowing up, what were the signs? Other than shifting hard.
Did you have coolant leak prior???
great video ,thanks . did gm solve there transmission problems ,if so what year ? thks
Transmission issues are still present on the 2019+ models. GM has released an updated transmission thermostat that you can pick up at a dealer. But they never issued any recalls
I did they same on a 2020 no change in temp
My 2015 subarban Mine Mine blew up 104k miles
How has it been holding up? Im looking at buying a 2018 with 40k miles and this is probably going to be the first thing I do to it to hopefully never have to worry about the torque converter/transmission going out
Occasionally I have seen hot temps if I am towing 2 mowers. For example if I tow for an hour straight through the city then temps will still get upwards of 200. But 90% of the time it stays 165-185 which is a lot cooler than before
This should be the first thing you buy especially for how cheap it is. I bought a used 2016 with 70k miles and at 90k miles a had my tranny acting weird. I replaced ATF and filter along with this mod no issues since
9/24/24. I have a 2017 Silverado 1500 and it has banged down shifting from 2nd to 1st since 50,000.. Took it to a dealer and was told it is normal for this trans. It continued for many thousand miles. Took it to a different dealer and told this has been a problem and it is the valve body, changed that and now at 80,000 back at that dealer and trans pan dropped and fluid is burnt and metal filings found. Told to rebuild over $5,000.00, with Chevy 1 yr warentee or new trans $7,000.00, what would you do.
My 2020 AT4 10 speed has never gone past 160. I just recently changed out the fluid and filter at 95K
GM changed the temp bypass temp to 160 on newer truck, 2018 and newer.
My 2019 Silverado goes too the 200-205.
You also probably have a more heavy duty torque converter in that 10 speed. These wimpy 6L80 torque converters just melt when the temp gets above 190
I just got a 2014 Tahoe police car, will need to change that piece?
Only if your transmission fluid is getting up into the 200° range. If it’s steady around 160-180 it should be fine
Where did you buy your transmission mission at that you put in your truck and about how much did it cost?
Autozone about $3500 but add on another $1000 for the core charge. I believe I paid the $4500 up front and then they gave me $1000 back when I gave them the old transmission
Experiencing trans failure right now on my 2014 at 150,000 miles
Sounds about right. Mine started shifting very hard and slipping around 130-140k and blew up pretty much as soon as I got to 150k. Bought a new 6L80 from Autozone for $3500 and swapped it in my driveway with the help of some TH-cam tutorials
This only works for the 5.3! NOT the 4.3!!
Really.
@@SerafinN26I installed this 2 weeks ago and I still get up to 196! I’ll be installing a separate trans cooler for sure!
I’m gonna assume you drained the transmission fluid before doing this ??
Nope left it full and it only drained a little bit of fluid out when I took it off
@@StrongTurf I’ve noticed my 2014 is starting to shift hard in lower gears even before getting warmed up. I don’t do much towing if at all, been curious if this will help fix along with a trans filter/fluid dump.
@@ryandurham5725depends if you have already changed your trans fluid regularly. I didn’t change mine until 100k, then it started shifting hard at about 120k, changed fluid again at 140k then it blew up at 150k. I would only change the fluid if you have already done it often. Otherwise just leave it.
mine went at 110,000.
Should I do this with my 2008 at 156000 miles and the only gear that shift hard is going into second but only when I punch it
It can’t hurt. It definitely won’t take away the hard shift but it can prevent it from getting worse
What's the name of this part
Thermal Bypass Valve
@@StrongTurf okay thank you
Can anyone please let us know how you check the fluid level now with this thermal bypass? So many different answers, I’m totally confused.
Should not change anything. Unless you also added a deeper transmission pan to allow a bigger capacity. But the fluid check procedure should be the same after doing the thermal bypass
@@StrongTurf aaaand that is what????? Not one video with these bypass mods show how the fluid should be checked properly, which is the most important step missed. The instructions say no warm up needed. I phone the place and they say just check level whenever. This is exactly why I’m asking the question.
You should be able to check the fluid immediately after starting the truck. Fluid flows immediately. So you don't have to heat it up to open the thermostat.
Depends on what transmission you have. The 8-speed like mine doesn’t have a dipstick to check the fluid level.
Is this the same part number for the 8l90e transmission ?
I believe it would be a different part number. Mine is for a 6L80
@@StrongTurfit's the same part. 6 speed or 8 speed.
Just happened to me. 176k
If it don’t happen sooner it will happen later
More Chevy shit !!!!!!!
