- 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:

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!
Which transmission do you have and how many miles? I have 8l90 and the transmission is shuddering. Fluid is already turning brown again and the dealership didn't tell me.
Chevy and brands always burned up transmissions. Trucks with overheating transmissions go back as far back as 1983 with my Chevy Blazer and more with my fathers. My transmission overheated, burned the cooling line that passes through the radiator, sent water into the engine that boiled out the dip stick onto the manifold and started a fire. Today I always add an extra transmission cooler if the vehicle does not always have one. My 2004 Jeep grand cherokee has not had any problems towing my 3000 pound boat. Thanks for the information about the thermostate.
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
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
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
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.
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.
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
Also known fact if the fluid doesnt get to operating temp then its going to cause more drag cuz the fluid is thicker. Either A" put the lower temp gm thermal bypass block in or B put it back in the winter and swap out in summer. Gas mileage sure goes down some from winterized gas but the trans operating temp is above I believe 145. If you put in a trucool 40k cooler with the bypass delete that cooler has an internal bypass that routes the fluid through part of the cooler until it gets up to temp then flows it through the hole cooler.@Doof3rproductions
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 just replaced my 6speed in my 2011 tahoe with upgrade billet components its been great ,my 2014 ltz transmission issue was experiencing rattling noices when 55-60mph dealer agreed to fix since I had warranty however ended up hiring an attorney dealer done some shady business practices but I'm looking at 2017 ltz with 83k miles 1 owner clean truck I really want to buy it but want to prevent any issues ahead of time thanks for the info
I have a 2017 Sierra. I just changed mine yesterday! Temps are at least 20deg cooler...
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.
That was some serious mileage on the truck without changing the fluid but for the transmission to completely blow is insane anyway
I just added an additional Mishimoto transmission cooler as well as installing the Superior Solutions bypass kit to my 2016 Silverado LT. In daily driving the temperature has been running below 120 degrees F. It will be interesting to see what the temperature is when I tow my 8400 lb travel trailer next summer. Even with the updated GM thermostat my temperature was running 180 degrees while towing.
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.
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 high temperatures does cause problems along with the inferior material the converter is constructed from I changed my converter to a billet one along with the cooler upgrade
How has that been holding up for you boss? I’ve been wanting to do the same thing for my Silverado.
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...
my 15 has 128k and the fluid is fried. Went to Geese Monkey and did the fluid flush which includes the torque converter. Wonder if this was a little too late, It still shifts nice but i will still change the stat. Thanks for the great video.
Prior to your transmission blowing up, what were the signs? Other than shifting hard.
Did you have coolant leak prior???
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
Great suggestion MOD. Just purchased a 2018 Silverado 1500 V8 4x4 and will add this PPE to my transmission. Have you done the Oil separator/ catch can kit?
Would a better cooler be cheaper or more practical?
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
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
Why do you think GM set the original temp 194 so high ?
Bro get to the point.
Great Video Thank you.Will this work on the 8L90 Transmission? " 8 speed" 2017 Silverado..
I’d recommend the superior solutions for the 8l90. I have an 18 Silverado and live in the desert. Easy install and dropped temps dramatically. Mine never gets above 145, even in triple digit heat.
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
Is this the reason the 8l90 trans are going out?
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
Listen thank you from Jorge Garcia Dallas Texas
Is this issue happening to ford trucks too model 2013 6 speed
Change transmission fluid 2 different one and put that on
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
Thanks for the info 😊
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
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
I did they same on a 2020 no change in temp
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
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 2017 went out last year at 68k. Took the new trans. due to parts shortage. I got a 3 year, 100k mile warranty.
My 2015 subarban Mine Mine blew up 104k miles
Hey how is your truck
The new thermal bypass on the truck is still doing good. Only ever got over 200° a couple times when it was over 100 outside and I was doing long drives while towing. Other than that it’s keeping the temps where they should be.
Now I just have to address all the other stuff that’s wrong with the truck 🤣
@ i just got the truck this month I have problems with shifting lol 😂 thanks for the video every time I slow down it shift down hard
@ my recommendation would be to not change your trans fluid. Keep it dirty. I didn’t listen and I changed the fluid when I noticed the hard shifting. Then my transmission blew up less than 10,000 miles later. The dirty fluid will help the worn down gears grip better. And the thermal bypass valve will help prolong the life as long as possible. I got my new transmission from Autozone for about $3,500 and put it in myself with the help of a youtube video from Express Auto Transmission based out of kansas
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.
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
What's the name of this part
Thermal Bypass Valve
@@StrongTurf okay thank you
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.
i have a 2018 Silverado 1500 and my transmission just completely went out at only 64K miles. unbelievable. 4K miles out of warranty, go figure. dealer wouldnt do anything about it. Im only now going down the rabbit hole of these shitty 6L80 tranys that have obvious failure rates and yet GM continues to use them. I drove my F150 for 180K and never thought once about the transmission going out and now my chevy died at 64K and with proper regular maintenance?!?! Big WTF GM, WTF. Im looking to do a full replace with aftermarked billet converter, im going to bypass the active fuel management system and maybe something like this part to help my trans temps.
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.
Got a pinch a Hagen
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 UA-cam tutorials
5000 installed
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!
mine went at 110,000.
Just happened to me. 176k
If it don’t happen sooner it will happen later
More Chevy shit !!!!!!!
WTF is it called ? Spit it out!!! 👎
20 minutes of BS!
Thanks for your feedback, sorry that you have the attention span of a squirrel and can’t sit still for 20 mins
I got a GMC sierra SLT 2018 my transmission temperature stays around 180 got a 98,000 miles on it but when I do get on the freeway and start to catch speed. I notice if I push it too hard I’ll get a flutter.?
