DIY: How To Keep 6L80 Transmission From Overheating On Chevy/GM 2014-2018 | Pill-Flip, Sure-Cool Kit

[@eddiemoreno2922]

This does work, I bought my 2018 Silverado brand new, and I installed it 6 months later and mine runs 40 degrees cooler, and I live in the desert southwest.

[@TheWorldCruisers]

Yep sure does… we live in Central Valley California and gets up to 118 degrees here.. this mod definitely kept the transmission temperature low..

[@floydstime]

Love this. I would add two things. 1. Cover your transmission lines with a plastic bag so no dirt gets inside. 2. Use QD Electronic Cleaner instead of break cleaner. Transmissions hate other fluids, even small amounts and QD leaves no residue. Use the QD to clean the crap out of the inside of that block and all components prior to assembly, and spray some on a lint free cloth to wipe the ends of the lines prior to installation. If even a speck of dirt gets inside your transmission, it could cause catastrophic failure. Pretend your are in a clean room when dealing with transmission guts.

[@TheWorldCruisers]

Great information! Thank you for your comment and suggestions.

[@austinortiz361]

I live in Texas today my transmission hit 194 so I just ordered the Superior’s Cooler Flow bypass valve kit

[@TheWorldCruisers]

This kit really helps but I still recommend swapping out the Torque Converter as soon as you can if you have the 6L80e transmission. You could go with an OEM CTSV torque Converter.

[@alristitov]

@@TheWorldCruisers Well, I can tell my experience that once the factory torque converter is on its last legs, the temps will rise from the ignorant factory temp of 190 to 220 and beyond. I bought my truck used, 16' 1500 "HD"; First pull with the trailer after I bought it, It would not shift out. Got worse and worse the further I got, by the time I got off of te interstate it was in second gear to maintain 55mph. 67000 Miles. I have owned several Fords well over 100k and over 30 years old on a couple, never had to do more than change a water pump.

[@rxjefe]

I have a 2017 Silverado and just spent $5000 on repairs for my 6l80, got thermostat bypass installed, gears at 4.56 and new radiator and engine thermostat and my transmission temps are hitting 220 while driving (no towing) and trans temp will get up to 230-240 if I’m idle for a long time. Took my truck back to transmission shop and they keep telling me everything is fine and 6l80s “just run hot”

[@TheWorldCruisers]

I’m no transmission professional, but from my research they should run 175 degrees plus or minus 25 degrees. Maybe get an opinion from another transmission shop because that seems a bit too high to me. I will ask my local shop here as well and see what he says. What size tires are you running?

[@huntfishsmokemeats]

Trans cooler is prolly plugged

[@rxjefe]

⁠@@huntfishsmokemeats you are correct I had my transmission flushed and lines cleared. Haven’t had an issue since. Transmission sitting around 140-160 during winter and around 180 during the summer now.

@@TheWorldCruisers Stuff like this saves people thousands of dollars, and we need that more than ever these days.

[@TheWorldCruisers]

That’s a reason why we wanted to make this video. We’re glad it was able to help you. If you have the 6 speed transmission I would recommend you to upgrade your torque converter to a Circle D or ZL1 torque converter as the factory one is prone to failure and also taking out your transmission.

[@JasonEllingsworth]

@The World Cruisers yes sir i already have been looking up how much that would cost vs a total replacement. Looking at around 500-1000 vs 3000+

[@alristitov]

Excellent video, I am still disgusted with Chevy setting their trucks up to fail like this. I am already on my second tranny, about to replace AC condenser as it has the notorious leak all of them Will end up with. Being as I am going to loose tranny fluid as the Condenser is also shared with the transmission cooler (another genius idea to sell parts), I am going to nip this in the bud; damn thing gotta last until I can afford to ditch it. I still feel like 165 degrees is rather high for no load. I do not see a point in that O-ring on the "pill" wonder if that would shave a few more degrees off to have a slight trickle of flow.

[@TheWorldCruisers]

Thank you! Yeah, these trucks were definitely not put together very well…. My transmission went out in December 1.400 Miles away from home… the torque converter went out and took the transmission with it. The mod helps but the real problem is the torque converter and the factory TCU tune. Best economical way to fix the transmission issue is to swap out the torque converter with the ctsv or the ZL1 one which doesn’t need tuning. But would recommend to get your TCU tuned anyways. Most shops will know what I’m talking about.

[@alristitov]

@@TheWorldCruisers I actually do not know what TC was used, the paperwork I got after using warranty to get it fixed.. is quite vague and I had to fight like hell to get it from the idiots. I need to take care of the heat though, I can tell a drastic difference as it heats up, which takes right at 40 mins to reach 196.

[@juanyoi87]

Thanks for making the video. Is there any updates on how your truck is running with the mod.

[@TheWorldCruisers]

The truck was doing great and the transmission temp never got high until last week after a 5,000 mile trip which was because of the Torque Converter going out and it took out the transmission in the process. So my recommendation is to do the mod or updated GM thermostat and change your Torque converter to a ZL1 or CTVS one.

[@TheWorldCruisers]

I would try to drop the pan to inspect for metal shavings, try to flush the transmission, and take it to a tuner so they can tune out the TCC lock out. Hopefully you can still save it…. Our transmission unfortunately went out and now in the process of having it rebuilt and using a CTSV torque converter.

[@Slo_N54]

Yeah flipping the pill made it worse for me tbh so I’m switching by it back

[@4mudski]

It don’t work for the 4.3 v6!!! Only the 5.3

[@Slo_N54]

@@4mudski that’s good to know now

[@MrLuckylilly]

@@Slo_N54 I have a 2014 4.3 and did the pill flip. Works good so far, but the converters are cheaply made. A trans tech on youtube said you should remove the stem by pulling it out or it may loosen and cause problems. It was a Cottmans trans tech. I also pulled the pan , changed filter and had a drain plug welded in. Some techs are reccomendeding replacing the TC with a billet TC.

Thanks for this! If I make this change now, will it help in the long run, or has serious damage already been done and it is too late. I swear I've had this transmission issue since I bought the truck new in 2018, but it was rather subtle so I didn't understand the extent of the problem.

[@TheWorldCruisers]

It might help with the temperature but honestly sounds like your transmission will go anyways. Best thing I would recommend is have the torque converter swapped out for a ZL1 or CSTV one and have a transmission shop flush or check out your transmission. The factory torque converter usually starts going bad because of the factory tcu tune and ends up taking out your transmission along with it. Ours went out this past December even though the proper maintenance was done and I had this mod. Temperatures never got hot until it finally just went out . And it was real sudden.

@@TheWorldCruisers I really appreciate the advice. It's a real shame. I love this truck otherwise. Truthfully, best vehicle I ever owned. Maybe it's worth a new transmission, haha.

Before you replaced any of these parts was the truck kind of shaking when you accelerate after the transmission warmed up?

Trying to fix small things before i decide to rebuild it

[@TheWorldCruisers]

Not really, I was just taking a precaution because we live in a hot climate and didn’t want to take any chances. This is will help but eventually the transmission will go out. I recommend doing this mod and take the truck to a place to tune out the TCC lock out in the first four gears.

Try to upgrade the transmission cooler with a true-cool one and have your TCU tune out the TCC out of 1 thru 4th gear. If that doesn’t work then most likely your torque converter and transmission are already toast.

Yes, we do. We had to put in a new built transmission in this year. If you do get the Tahoe, we recommend you to take it to a shop that tune out the factory torque converter lockout, upgrade the transmission cooler and have the updated transmission thermostat from GM. Also, if it’s in your budget do the DOD delete and don’t just shut it off with a handheld tuner.
