You’re the man! I have a 2015 Yukon and it doesn’t have the 10mil bolt holding the lines in, you are the only person to mention this, thank you I wish I had found your video first!
Installed this on my new to me 2017 Silverado with 46,000 miles about a year ago. My transmission temp runs at an average of 145 after the install. And the highest I've ever seen it was 170 on hot day and running up a 7 mile hill on PA turnpike 😊
Thanks for posting this video. I heard about this and thought it was going to be a tremendous task to do. Seeing your video shows it's doable to even someone who isn't a "mechanic". 145 degrees???!!! awesome!
Had to replace my transmission on my 2014 Silverado a year and a half ago. The dealer didn't do the thermostat update. Going to do this mod an hope it prolongs this transmission's life. Thanks for the vid!
Just gonna throw in a comment, this summer it was getting to 100-110 in Texas. On longer drives I was sitting between 170-180 with it maybe going to 190 if I would get stuck in traffic. I just went back to these because we experienced our first cooler days of 60 and it was taking a while for it to get over 100 but after about 20 minutes I am sitting at 130. This does work great if installed properly!
yeah it’s dictated based off of the ambient temperature outside. So if it’s really hot outside, you’re still gonna be on the 180 range which is fine. The key is you have fluid flow constantly now.
Just installed STL010 on my 2016 6L80E really dropped the trans. temp 50 degrees today trans never got past 127 degrees I had the older thermostat that ran it to 194 degrees so big improvement
Thanks, checked your video before going under, knew what to take with me and watch out for. I did do the TSB for the new bypass replacement though not this kit.
@Global Transmission Parts I ordered mine from u guys right away when I saw these results. I have a 21' Silverado with a 6L80 and it got up to 205° F. All I did was wheel it in the hills I don't even tow with it. The UA-cam community saves the day again. And thanks to G.T.P. just waiting for shipping.
Did you lose enough fluid you had to add? I’m planning to do this but the 2021 doesn’t have the dipstick and you have to add from below the truck. That seems like a pain in the ass, along with trying to make sure it isn’t under or over filled.
Definitely gonna do this to my sierra before I pull my car with it! Can't believe that gm put a thermostat on these transmissions. Would make alot of sence that the heat they make could be a cause to some of the problems they have with the expansion and contraction of the materials and the fluid breaking down faster with the heat
I love the way you are thinking! I thought the same! It’s 115 in Phoenix the last couple days and I have been staying around 170 after driving 30 mins! Let me know when you tow with it, I haven’t towed yet.
@@sbc_jake_9677 , I heard from a YT video someone saying that the reason the original thermal bypass valve was designed to open for cooling at 194 °F (or 90 °C) is due to Federal Government regulations to get higher mpg. The hotter the fluid is the thinner it gets, which would enable higher mpg. However, I think GM failed in providing a transmission fluid cooler coil that’s capable of sufficiently cooling the fluid for city stop and go driving as well as towing something (highway driving is ok - doesn’t overheat, because of cooling air with speed). Also, it appears that over time, the thermal bypass internal gets clogged up a bit with fluid gunk or deteriorating components rendering it to operate inefficient that leads to creeping up higher temperatures.
I can't believe this either. Ive blown 3 torque converters and had my transmission rebuilt 3 times under warranty within 2000 miles of each other and by doing my research this is the product that I think is going to be a savior. the common denominator of each failure was long trip and by my house in southern ca we have a toll road hill that is long and pretty big and it takes my torque converter out and I believe the fluid is just way to hot.
Will adding this to my 'New' transmission when it comes in. Have a 14 with 149000 and mine has the GM faulty tranny. Brown fluid, temps as high as 190 plus on summer day. Bucks when you first put it in D of a morning. Searches for 3-4 or 4-5. Im biting the bullet and replacing everything. New torque, lines, cooler and a Jasper rebuild. No chance for that old fluid getting into system. Its a Hell of an expense but I hope it will keep the truck going another 150000. Thanks for the video.
My 14 looks good for the years it has just had to do mine at 160k…. 5k for a trans and maybe another 5 k for a good engine rebuild when the day comes I personally think is better than a new 60k+ truck I only paid 31k when I drove mine off the lot
Thanks Bob. Hey, I don't have access to a lift, to lift my truck. Can I use ramps, without all of the transmission fluid leaking out, when I take off the thermostat block?
Did this to mine. I only drove it for about 15 mins but never went passed 127.. before it’s have already been up to 190 doing the same drive. Thanks 🙏🏻
2 month later, still working pretty well but if you’re going to be driving on long trips I’d say 4 hrs away or more I’d invest in trans cooler to keep it cooler or it will go back up to 190+
I have tranny cooler and it's a 6l80e looking to do this it runs at 185 rite now about planning on doing a lot The question is how much farther is this really going to extend the life of the transmission there really only good for about 150 200,000 If you change your fluid every 40,000 mi as far as I know One would assume this should extend the life slightly especially if you're telling If you never tell or haul anything this might not be a necessary mod for you I'd like to know what the Camaro runs at
Installing mine when it gets here monday on my 18 sierra , just replaced the trans pan filter and went with mobil 1 blue label tranny oil already i feel the difference smoother shifts temp is down to 180s compared to 195+ cant wait to see how much better it will get with this delete kit
Dame nice I noticed eveytime my transmission hit 194 it starts shifting ruff in traffic I thought the guy behind me hit me one day got this going to give it a try
Got my kit installed a couple days ago and I’ve had no issues at all. Before I installed the kit, my trans ran between 180 and 210 daily no matter how my driving style was. Now after installing this kit my trans runs between 158 to 175 regularly!!!!!!!!! I’ve never got my temps down to the 145 range but I do plan on putting in an auxiliary oil cooler also. Normal driving conditions, it’s my daily driver and never abused, outside temps in my state have been in the triple range for going on 3 weeks now and it still runs loads cooler. I’m happy I got the kit and couldn’t be happier 😎 Thanks guys
It should! I believe the 2011 had the 6L80 but I don’t think it had a transmission thermostat like the 14+ look into a larger transmission cooler like mishmoto
Nice! I love it. AJT Design injected fob. I made a video on it! Check it out! Also if you like this video hit that subscribe button I’m a new channel just starting out!
Think Ill be getting one of these for my 17 Sierra… seems like the way to go. Does the slight leak of fluid shown in the video pose any issue or need to be topped off again?
At 04:30 I explain checking the level. It’s always a good idea to check level and add if needed. Thanks for watching! Remember GM makes one for these trucks as well now because it was such an issue.
The update and thousands of other people that also have this sure cool kit love it. The guys over at superior transmission parts know what they are doing. I highly recommend this upgrade. I do not recommend just plugging it or flipping the thermostat. You want to have the pressure relief ball too so in cold weather it has the correct flow.
I always recommend doing more research. But trust me you do not want high temps in these transmissions. I have been a tech for over 15 years now and GM tech for most of it. The only reason they are allowing these transmission to get so hot is for fuel economy. Just so they can add that extra and make it look good. I would rather have my transmission properly cooled and lose a small amount of fuel economy. So little you will not even notice.
Thank u so much for the info. I’m still going to change it . Just wish I could find some one that would tell me how it works . That’s what I’m interested in
Basically it allows flow through the cooler at all times. It has a soft spring that eliminates back flow and then the check ball is for cold weather if the cooler is frozen and can’t flow the fluid will feed right back to the transmission.
Yes sorry.. was new at filming and couldn’t get the camera set up so I could use two hands and I only had limited time.. I recommend making sure there is trans fluid on everything for lube. and a little PB blaster would also help..
@@Bobsgaragetech I PB blasted a pool over the snap ring for a few minutes before I even went to remove it lol. Came right off at 70k miles, I guess I got lucky. I am considering getting the new valve upgrade Because the operating temp is taking extra long to reach due to the whole reservoir being cycled. I think the new valve cycles at 150F and will need new lines (I have QD) but I think its a better option for reaching optimal operating temp
Yeah it sucks. It DOES keep your oil cool for longer but it creeps up until 195 and by that point the truck has noway to cool the fluid at all cus you have no thermostat. I found out that GM made a recall on this for 2014-2015 trucks and you have to buy new trans lines with the upgraded thermostat. In Louisiana the heat was 100-105 outside and trans temp never got over 180 with the upgraded transmission thermostat/coolant lines.
Now that the weather is low 80s here the trans temp doesn’t get above 165. Remember, the transmission needs to heat up and get to operating temp to work and flow right. 140-180 should be good for trans
I did order this thermal bypass kit and will be comparing it to the mishimoto one that came with the transmission cooler.. I installed the mishimoto cooler with the thermal bypass delete and went on a long highway drive with outside temp at 85 and noticed the transmission temp never went over 150 degrees, upon returning in town and driving around some more trans temp fluctuate between 127-135... plus I noticed it shifts smoother. I'm just concerned if these are good temp and not too cold since dealership said normal operation temp is around 180 and up.
They also say normal oil for these trucks is 5w20 yet when they sell the same Gen V engines for commercial use (where they dont care about MPG) they recommend 5w30... Dont listen to the GM engineers at this point, they only care about CAFE standards and not longevity of thier products.
@@AmericanNuke54 Yup, also GM just released the official thermostat bypass similar to this, they knew this was a problem but didnt fix it. idk why i keep buying these shit trucks.
based on what I've been reading it can be an issue in a cold climate (Northern parts of America), so new GM TBV is recommended. The new TBV opens up at 70 C / 158 F, which would keep the engine around 165 F in warmer temps and closer to 158 F in colder temps. I'm planning on getting the new GM TBV because I don't want to void my warranty plus the installing the new TBV on 2016 - 2020 Suburban is super easy. Will switch later when I'm out of warranty based on feedback from people who have done either one of the modifications/upgrades.
@@chaddelecia2414 Had mishimoto trans cooler with sure cool throughout all winter last year in Midwest with temperatures in the negatives and it seemed to warm up just fine.. still running strong.
@@919blackangelchange your fluid with amsoil. I bet that’s the issue. If you have the OEM fluid in. It’s garbage. I did mine with 44k on it today and didn’t hit past 133deg I just changed it last week with amsoil though.
Once you install this and you check trans fluid immediately am I looking for the fluid to be in between the cold range or hot since you can now check the fluid instantly? Thanks
Yeah, watching this was like trying to catch Santa Claus dropping off presents as a kid. Felt like i missed it as soon as I nodded off, except I didn't nod off. Lol
The STL 010 kit IS FINE FOR CANADIAN WINTERS. Even with snow on the ground in a wet west coast -5°C day my 6L80E tranny always gets up to temp 150 - 160°F.
@@James-rk6go Here we often see -30 celsius, so I will take no chance, I will use Amsoil syntech ATL witch is good to -65 Celsius and up to 245 Celsius
Nice upgrade! Your video title should really not have the the words "Thermostat Delete" though, since you are actually doing a Thermostat Upgrade. Your statement about not having to warm up the transmission to check the fluid level may not be correct, because you still have a thermostat installed, so the fluid temperature will still need to be above the installed thermostat rating before it opens and allows fluid flow through transmission cooler.
Hey thanks for your comment, I do want to point out that it is not a thermostat what’s so ever. Check out the link in the bio and read more about the product. Thanks again for watching! 🙏
Thanks for posting this. Old retired GM tech here, just bought a used 2018 Silverado. Will get this changed out pronto. Will you post something on the AFM problems and solutions? Thanks Again Update: Installed the Sure Cool today SUPER EASY now the trans temp hold pretty steady at 158 before it would easily go above 190. Great product.
@@dustinturner5119 Thanks I have seen these.Great idea. I was also thinking about a complete delete after power train Warranty expires. Looking for recommendations on those
@@stevecampbell7620 no problem and yeah I waited to late and the lifters went out in my truck.. $3,800 later I decided to put the AFM disabler in it 😂 this happened at 91,000 miles for me

@@Bobsgaragetech thanks for the feed back, that really helps. I’ll see if i can get to the bottom of the issue. I’m not going to give up on the product just yet because it makes the most sense out of most of the thermostat deletes.
@@Vill254 just a heads up, if the converter has started to slip / chatter on TCC it could drive temps higher. and in the beginning of failure you may not even feel it slipping if it was during a pull / tow / haul situ. you may still need to add an external ( oil to air type vs. the factory heat exchanger inside the rad) if you bypass the rad heat exchanger (oil to coolant type "cooler") rule of thumb is install 2 of the Hayden / tru-cool coolers in series and make sure they are 1st in the air flow path (no obstructions in the air flow thru path) OTHERWISE if you have some other items causing lower air flow across the cooler (due to lights on the grill or grill guards / bumpers etc. ) GET the NEW TRU COOL WITH the automatic electric aux fan units (either the biggest single or 2 doubles. feel free to go to our website: www.superiortransmission.com there is also a contact us section if you need further questions answered or are just wanting to touch base. thanks ! p>s> 180 deg. F is fine all day long in 90-120 deg. if it gets higher add cooler if not, you may need to go into the unit.
I see the 2 links up there to Amazon, what is the difference between the 2? I would prefer the one you installed. I assume the first link is a bypass that you didn't use and the second is what you installed?
270 Jesus man. You need to replace with amsoil and this bypass. 275 you get an alarm and 290 it goes into limp mode. Your trans might be toast already.
@ngirardo86 honestly I just replaced the bypass and my truck is running like a champ . Also serviced the transmission. 2 transmission shops told I had to replace it. But no still good. I even went to mexico twice
@@MarioMartinez-zk2wk if you drove it with it hitting 270 degrees then I can almost tell you without a doubt you did some damage to that transmission. Just keep an eye on it.
Transmission has 114k on it. Transmission oil has 3k on it. No issue with tranny. I just don’t see how this really does anything when my motor temp runs at 210 degrees
It goes in exactly how I had it built. I just didn't show myself actually sliding it in the housing. The product comes with detailed instructions this was just a fun video showing where it goes and how it works. With some install tips. GM actually makes a factory replacement now fixing this issue. Good luck!
@@Bobsgaragetech I'm definitely getting this done to my 2014 asap.. about two years ago.. my tran died on me and it was due to the torque conv fragging out from the heating issue.. $4200.. new torque and reman trans from the Chevrolet dealership.. 30K mile/3 year warranty.. so I got that at least.. lol.. Thanks, Robert!!.. CHEERS!!
@@919blackangel I had an aftermarket cooler installed but they screwed me, was suppose to run inline with radiator and they bypassed it instead , still runs at 190. The only thing I believe would help is the tru cool 40k cooler and a deep transmission pan. Allows for more fluid, which should reduce heat up
There are other issues that could cause your temp to get that high. I have seen locked up or failing torque converters. Slipping clutch packs, broken or worn sungears… old transmission fluid was another big one.
This isn’t the best modification for the colder climates. I have had this bypass/delete installed for a year now, and I’ve found the operating temp is far too cold for my liking thru the winter. For most of the winter, I have only seen the hottest operating temp Of 70 degrees F. I don’t think this is a good idea for transmissions to run that cold. I would suggest putting in the updated 155 thermostat for the winter months if you’re running empty with no load.
@@gerardocuarez9034 I don’t know. I’m not saying not to do it, but up here in Canada last winter, my transmission temps never went above 55 degrees F for the whole winter. I won’t know if that’s bad to run it that cold or not, but that’s not running anywhere near to what normal operating temps are.
I should also add…..in the summertime, this is a great mod to run in the warmer temps of the summer. Pulling a camper at any time, the temps consistently stay about 50 degrees cooler than before. Always about 140 to 150 now. Before the mod, they all run right around 200 to 220….that’s scary stuff when pulling.
Am I the only one who’s noticed this is the cleanest 2018 undercarriage you’ve ever seen in your life? Shit look at the oil filter, screw the mod I’d like to know how the hell it got that clean.

What’s the difference between doing this kit or just flipping the spring I seen on other videos thanks
I did the “pill flip mod” on mine. Granted it’s cold out now but hasn’t got over 140 at all
Anyone just remove the thermostat and spring and put back together. Would that be fine instead of flipping. Same thing right
Do you HAVE to use a Milwaukee tool or will a DeWalt work?
Has to be Milwaukee or anything but DeWalt.. sorry LOL
snap on will suffice, anything lesser quality will ruin transmission.
Put down the pipe.
Will that work ?!?
Do you know if they make one for my truck.. 2011 Chevy silverdo
It should! I believe the 2011 had the 6L80 but I don’t think it had a transmission thermostat like the 14+ look into a larger transmission cooler like mishmoto
Hey thanks for commenting and watching the video please subscribe if you liked my video!
Need to do this with my 19 z71 tahoe. Pulling my atv on a 6x12 utility trailer I get up to 210 and stay at 195-200 normal driving
I did the upgrade and it works. Normal driving it stays around 135-160 thanks for the video. Also got it on eBay for 55 bucks shipped.
Awesome!!!
nice remote have it in tan.
Nice! I love it. AJT Design injected fob. I made a video on it! Check it out! Also if you like this video hit that subscribe button I’m a new channel just starting out!
all youtube vids shows top cap is easy to remove be ware unless you don’t need your truck until you can get a new valve plan for it.
Just have some CLR on hand. I did mine with 44k and 5 salt filled NY winters. CLR took all the crud off no problem.
You didn't show how to put the parts in
Think Ill be getting one of these for my 17 Sierra… seems like the way to go.
Does the slight leak of fluid shown in the video pose any issue or need to be topped off again?
At 04:30 I explain checking the level. It’s always a good idea to check level and add if needed. Thanks for watching! Remember GM makes one for these trucks as well now because it was such an issue.
Could u give us a up date please I got the kit . I just afraid that the transmission running to cold could cause a problem
That's the question nobody asked
The update and thousands of other people that also have this sure cool kit love it. The guys over at superior transmission parts know what they are doing. I highly recommend this upgrade. I do not recommend just plugging it or flipping the thermostat. You want to have the pressure relief ball too so in cold weather it has the correct flow.
I always recommend doing more research. But trust me you do not want high temps in these transmissions. I have been a tech for over 15 years now and GM tech for most of it. The only reason they are allowing these transmission to get so hot is for fuel economy. Just so they can add that extra and make it look good. I would rather have my transmission properly cooled and lose a small amount of fuel economy. So little you will not even notice.
Thank u so much for the info. I’m still going to change it . Just wish I could find some one that would tell me how it works . That’s what I’m interested in
Basically it allows flow through the cooler at all times. It has a soft spring that eliminates back flow and then the check ball is for cold weather if the cooler is frozen and can’t flow the fluid will feed right back to the transmission.
I see you skipped the part where you put the snap ring back in lol. That was the hardest part, I recommend using 3 hands. I flipped the pill
Yes sorry.. was new at filming and couldn’t get the camera set up so I could use two hands and I only had limited time.. I recommend making sure there is trans fluid on everything for lube. and a little PB blaster would also help..
@@Bobsgaragetech I PB blasted a pool over the snap ring for a few minutes before I even went to remove it lol. Came right off at 70k miles, I guess I got lucky. I am considering getting the new valve upgrade Because the operating temp is taking extra long to reach due to the whole reservoir being cycled. I think the new valve cycles at 150F and will need new lines (I have QD) but I think its a better option for reaching optimal operating temp
I installed this too but when I drove for more then an hour it WILL creep up to 195…..help!
Any update ?
Yeah it sucks. It DOES keep your oil cool for longer but it creeps up until 195 and by that point the truck has noway to cool the fluid at all cus you have no thermostat. I found out that GM made a recall on this for 2014-2015 trucks and you have to buy new trans lines with the upgraded thermostat. In Louisiana the heat was 100-105 outside and trans temp never got over 180 with the upgraded transmission thermostat/coolant lines.
Now that the weather is low 80s here the trans temp doesn’t get above 165. Remember, the transmission needs to heat up and get to operating temp to work and flow right. 140-180 should be good for trans
Does it Matter if it’s a 4.3 or 5.3?
No, but the transmission matters. The bypass valve has a list of transmissions it works on.
I did order this thermal bypass kit and will be comparing it to the mishimoto one that came with the transmission cooler..
I installed the mishimoto cooler with the thermal bypass delete and went on a long highway drive with outside temp at 85 and noticed the transmission temp never went over 150 degrees, upon returning in town and driving around some more trans temp fluctuate between 127-135... plus I noticed it shifts smoother. I'm just concerned if these are good temp and not too cold since dealership said normal operation temp is around 180 and up.
They also say normal oil for these trucks is 5w20 yet when they sell the same Gen V engines for commercial use (where they dont care about MPG) they recommend 5w30... Dont listen to the GM engineers at this point, they only care about CAFE standards and not longevity of thier products.
@@PrimeraRSTKD Did you mean 0W20?
@@AmericanNuke54 Yup, also GM just released the official thermostat bypass similar to this, they knew this was a problem but didnt fix it. idk why i keep buying these shit trucks.
based on what I've been reading it can be an issue in a cold climate (Northern parts of America), so new GM TBV is recommended. The new TBV opens up at 70 C / 158 F, which would keep the engine around 165 F in warmer temps and closer to 158 F in colder temps. I'm planning on getting the new GM TBV because I don't want to void my warranty plus the installing the new TBV on 2016 - 2020 Suburban is super easy. Will switch later when I'm out of warranty based on feedback from people who have done either one of the modifications/upgrades.
@@chaddelecia2414 Had mishimoto trans cooler with sure cool throughout all winter last year in Midwest with temperatures in the negatives and it seemed to warm up just fine.. still running strong.
Just wondering, are there any sensors this is going to set off by installing this? Also What happens when this part fails? will trans heat up or??
No Transmission still gets to operating temperature. This just helps full time flow to the cooler..
@@Bobsgaragetech Why don't they have full time flow for the engine? Why the need for a thermostat at all? is there a delete for the engine thermostat?
Ok but what keyfob cover is that?!
Check out my other video I do a install and review on it! Thanks🙏
Crazy, I just did this to mine and I’m still hitting upwards toward 186
Do u have any update ? I did my today and i have the same issue?
@@919blackangel mine the other day I checked and it was at 181. So idk if I should just buy the GM updated one or just do the pill flip
@@919blackangelchange your fluid with amsoil. I bet that’s the issue. If you have the OEM fluid in. It’s garbage. I did mine with 44k on it today and didn’t hit past 133deg I just changed it last week with amsoil though.
@@nathanmattner2358change your fluid with amsoil it will go down.
Once you install this and you check trans fluid immediately am I looking for the fluid to be in between the cold range or hot since you can now check the fluid instantly? Thanks
You don’t lose a lot of fluid doing this. I would check it a couple times. Warm is best.
Also GM came out with their own version of this thermostat.
@@Bobsgaragetech thank you . I’ll just run it for a while and check it warmed up . Is the gm version better or are they more less the exact same?
I’m sure they are similar, I have not had the GM version. I’m sure there are videos on that as well. Thanks for watching!
@@zbw8785it’s nowhere near the same. It’s a lower temp thermostat. Opens at like 135 or 140 instead of 190. It’s a direct replacement.

@@jonathanb9429 Exactly lol, Had me rewinding back thinking I missed it 😂
So, the fluid now never gets warm enough to evaporate the moisture in it.
the new part comes with instructions on how to put it back together.
I wonder how this kit would react in cold Canadian winter ???
Good question, I do know the company says it does work in cold weather. I also know GM came out with their own design of this for these trucks.
The STL 010 kit IS FINE FOR CANADIAN WINTERS. Even with snow on the ground in a wet west coast -5°C day my 6L80E tranny always gets up to temp 150 - 160°F.
@@James-rk6go Here we often see -30 celsius, so I will take no chance, I will use Amsoil syntech ATL witch is good to -65 Celsius and up to 245 Celsius
Nice upgrade! Your video title should really not have the the words "Thermostat Delete" though, since you are actually doing a Thermostat Upgrade. Your statement about not having to warm up the transmission to check the fluid level may not be correct, because you still have a thermostat installed, so the fluid temperature will still need to be above the installed thermostat rating before it opens and allows fluid flow through transmission cooler.
Hey thanks for your comment, I do want to point out that it is not a thermostat what’s so ever. Check out the link in the bio and read more about the product. Thanks again for watching! 🙏
What’s the hottest these transmissions can get? Just seen mine get up to 220F and cool down to 198F on a 100F day
I would say that’s about max.. At those temps the transmission fluid is breaking down faster. Those temps are a sign you need new fluid already.
Thanks for posting this. Old retired GM tech here, just bought a used 2018 Silverado. Will get this changed out pronto. Will you post something on the AFM problems and solutions? Thanks Again Update: Installed the Sure Cool today SUPER EASY now the trans temp hold pretty steady at 158 before it would easily go above 190. Great product.
You can get an AFM delete made by range. $200 you just plug it into your OBDII port. I have it on my 2018 Silverado

I flipped the pill on my 2014 V6, works great.
@@MrLuckylillyyou have now blocked the bypass. If a line plugs or kinks you are going to burn that trans up. This kit keeps your bypass.
After installing the by-pass my transmission still went up to 180 easily. Outside temp was 90 and i was only street driving for 30min.
Sounds like you have other problems. Could be clogged cooler, could be internal transmission failure, could be old fluid.
@@Bobsgaragetech thanks for the feed back, that really helps. I’ll see if i can get to the bottom of the issue. I’m not going to give up on the product just yet because it makes the most sense out of most of the thermostat deletes.
@@Vill254 just a heads up, if the converter has started to slip / chatter on TCC it could drive temps higher. and in the beginning of failure you may not even feel it slipping if it was during a pull / tow / haul situ. you may still need to add an external ( oil to air type vs. the factory heat exchanger inside the rad) if you bypass the rad heat exchanger (oil to coolant type "cooler") rule of thumb is install 2 of the Hayden / tru-cool coolers in series and make sure they are 1st in the air flow path (no obstructions in the air flow thru path) OTHERWISE if you have some other items causing lower air flow across the cooler (due to lights on the grill or grill guards / bumpers etc. ) GET the NEW TRU COOL WITH the automatic electric aux fan units (either the biggest single or 2 doubles. feel free to go to our website: www.superiortransmission.com there is also a contact us section if you need further questions answered or are just wanting to touch base. thanks ! p>s> 180 deg. F is fine all day long in 90-120 deg. if it gets higher add cooler if not, you may need to go into the unit.
@@Vill254 mines having the same issue did you ever get it solved?
Mine too
I see the 2 links up there to Amazon, what is the difference between the 2? I would prefer the one you installed. I assume the first link is a bypass that you didn't use and the second is what you installed?
Sorry the links are doubled. They are the same product. Both STL010

My 6L80 hit 237 degrees pulling a medium sized trailer in the high mountains in 68 degree weather. It works ok yet, but do you think I did damage?
I would think at 237° some damage was done. Not sure what GM was thinking or if they were thinking at all with these transmissions
Remove guts. Tap internal hole for 1/4" npt plug. Install plug. Reinsert top. Done!!
My 2015 has the same block
The 15 does and should have the thermostat. I believe snap rings hold the lines in though.
You took a thermostat out just to install another thermostat?
Yes.the original opens up at too high of temp.around 200 degrees.Too hot.kills trans torque converter.New one opens up at 150 degrees.

Why would you not show putting the new kit into the block
Exacly what I said I hate when they make videos like this waste of time
I literally show it built right next to the old one. What difference would it make seeing it slid into the housing?
My silverado 2018 is doing 270 degrees you guys think this will work. I live in California. Weather is 60 degrees
270 Jesus man. You need to replace with amsoil and this bypass. 275 you get an alarm and 290 it goes into limp mode. Your trans might be toast already.
@ngirardo86 honestly I just replaced the bypass and my truck is running like a champ . Also serviced the transmission. 2 transmission shops told I had to replace it. But no still good. I even went to mexico twice
@@MarioMartinez-zk2wk if you drove it with it hitting 270 degrees then I can almost tell you without a doubt you did some damage to that transmission. Just keep an eye on it.
@ngirardo86 👍👍
@@MarioMartinez-zk2wk at 275 you get an alarm and at 290 the vehicle goes into limp mode. You were extremely close to both of those temps.
The 190+ is BS I put a brand new transmission in my suburban in the Rockies it hit 195 and quit shifting until it dropped to 180 ..
You have bigger problems then. Plowing before this bypass my 19 Sierra would hit 240 250 and still run fine.
Mine didn’t do anything for my temps
How new is your transmission fluid? Did you check cooler flow? How many miles on the transmission? Is your transmission already messed up?
Transmission has 114k on it. Transmission oil has 3k on it. No issue with tranny. I just don’t see how this really does anything when my motor temp runs at 210 degrees
Not bad.. but I wish you would've shown exactly how it goes together in the thermostat housing... later tater
It goes in exactly how I had it built. I just didn't show myself actually sliding it in the housing. The product comes with detailed instructions this was just a fun video showing where it goes and how it works. With some install tips. GM actually makes a factory replacement now fixing this issue. Good luck!
@@Bobsgaragetech I'm definitely getting this done to my 2014 asap.. about two years ago.. my tran died on me and it was due to the torque conv fragging out from the heating issue.. $4200.. new torque and reman trans from the Chevrolet dealership.. 30K mile/3 year warranty.. so I got that at least.. lol.. Thanks, Robert!!.. CHEERS!!
I installed this kit and it still goes up to 200 degrees
I know, i did the same thing today , do u have any ideas o update?
@@919blackangel I had an aftermarket cooler installed but they screwed me, was suppose to run inline with radiator and they bypassed it instead , still runs at 190. The only thing I believe would help is the tru cool 40k cooler and a deep transmission pan. Allows for more fluid, which should reduce heat up
There are other issues that could cause your temp to get that high. I have seen locked up or failing torque converters. Slipping clutch packs, broken or worn sungears… old transmission fluid was another big one.
@@Bobsgaragetech just had it rebuilt in March with better parts, less than 5k miles on it
This isn’t the best modification for the colder climates. I have had this bypass/delete installed for a year now, and I’ve found the operating temp is far too cold for my liking thru the winter. For most of the winter, I have only seen the hottest operating temp
Of 70 degrees F. I don’t think this is a good idea for transmissions to run that cold. I would suggest putting in the updated 155 thermostat for the winter months if you’re running empty with no load.
O you recommend to not do it,for those that live in the cold state?
@@gerardocuarez9034 I don’t know. I’m not saying not to do it, but up here in Canada last winter, my transmission temps never went above 55 degrees F for the whole winter. I won’t know if that’s bad to run it that cold or not, but that’s not running anywhere near to what normal operating temps are.
I should also add…..in the summertime, this is a great mod to run in the warmer temps of the summer. Pulling a camper at any time, the temps consistently stay about 50 degrees cooler than before. Always about 140 to 150 now. Before the mod, they all run right around 200 to 220….that’s scary stuff when pulling.
Am I the only one who’s noticed this is the cleanest 2018 undercarriage you’ve ever seen in your life? Shit look at the oil filter, screw the mod I’d like to know how the hell it got that clean.
Another brilliant idea from the govt is how we ended up with this.
So, did GM purposely overheat these transmissions?
I heard from a YT video someone saying that the reason the original thermal bypass valve was designed to open for cooling at 194 °F (or 90 °C) is due to Federal Government regulations to get higher mpg. The hotter the fluid is the thinner it gets, which would enable higher mpg. However, I think GM failed in providing a transmission fluid cooler coil that’s capable of sufficiently cooling the fluid for city stop and go driving as well as towing something (highway driving is ok - doesn’t overheat, because of cooling air with speed). Also, it appears that over time, the thermal bypass internal gets clogged up a bit with fluid gunk or deteriorating components rendering it to operate inefficient that leads to creeping up higher temperatures.
My temperature goes up to 220 with that kit
You probably have something else going on.. to list a few.. old fluid, failing torque converter, slipping clutch.. etc..
Thanks!

Just take out the thermostat. Nope, let’s see who we can sell another thermostat to
good informative videos. but your intros are WAY too long. intro on this one is 1.15 out of 5.53 for the total video...
Why the fuck will you make a video and not show how it gose in the thermostat
I apologize the video was edited out. But you can see in the video with the valve ready to be installed.. it goes in the same way it came out..
You always check the fluid hot and running no matter if it's going through the cooler or not. Do not listen to this guy.
What the hell, you show nothing about installing the kit... Click bait....
I take the block off and remove the original thermostat. The sure-cool kit comes with really good instructions I just went over stuff other than what is written on there instructions. Nothing click bait here..
