How To: SAVE Your 2014-2019 Silverado Transmission! EASY! 

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!

My 2017 3500hd has no trans thermostat stock. I added coolers and now stays under 170 towing and 145 normal driving. Great truck!

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 .

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

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.

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 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 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

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 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.

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.

I did they same on a 2020 no change in temp

Where did you buy your transmission mission at that you put in your truck and about how much did it cost?

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 changed it on 2024 Silverado temp never goes over 175 degrees

Bro get to the point.

Is this for the 5.3 or 4.3??

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

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

My 2015 subarban Mine Mine blew up 104k miles

My 2020 AT4 10 speed has never gone past 160. I just recently changed out the fluid and filter at 95K

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.

I just got a 2014 Tahoe police car, will need to change that piece?

Experiencing trans failure right now on my 2014 at 150,000 miles

I’m gonna assume you drained the transmission fluid before doing this ??

What's the name of this part

Is this the same part number for the 8l90e transmission ?

More Chevy shit !!!!!!!
