I am glad I stumbled across your video I did not know there was a peace made specifically to do that and I'm getting ready to do mine on my 2014 based on many KZfaq videos thank you I really appreciate you putting this out like you said little bit of insurance for 30 bucks goes a long way with the transmission these days

I found TSB 21-NA-199 and had it done on the GM reman 6L80 I had to have installed after my original transmission went bye-bye. OEM parts, done by the dealer at no charge at the time of the new transmission install, it allows the fluid to start flowing through the cooler 34 degrees sooner. One of my cooler lines was weeping at a crimp so they replaced both lines during all this for free. I’m not into aftermarket parts and won’t put them on my truck, so the delete kit thing can’t speak on, I go OEM.

5:57 good videos. I just replaced my 6L80 transmission cooler lines with Dorman kit and tried to put the transco bypass kit in but the first part that goes in wouldn’t fit in the bore. Going to try the superior solution style.

Good argument BUT with the pill flip, the transmission doesn’t get even near temperature to cause that pin to work out. I’ve monitored mine and it runs consistently 50* cooler than before

the STL is the best kit from shift technologies.

My 2015 max temp goes to 175 should i make the switch ?

Can transmission be drill and tap for an fitting to eliminate block all together

Do you have a part number for the superior solutions? I am trying to get it through advanced but don’t see it anywhere except Amazon and eBay

Man for years I just drill and tap the thermostat and red lock title a pipe plug then there is no restriction. Springs or whatever.

Thank you for this video. A friend who has a similar truck to mine just told me about the 150 t-stat swap. I am skeptical about it. What I'd like to know is, is it mandatory to have the TCM reset and relearn or will it relearn over time? Or will a scanner reset or battery disconnect reconnect help the issue? I've also heard about the Mobile 1 Blue synthetic being the correct replacement for these transmissions because there was an experimental fluid used on certain models that didn't work. Any thoughts on all of this. Thank you again!

GM sell new one open at 71c it was 91c before

I did the surecool. With temps in the mid 80’s the trans runs at 130-140. My question is now where should my fluid measure on the dip stick? I just followed the cold measuring process. Anyone have more info on correct fluid measurement when the trans never gets to the hot measurement process? 2017 Silverado 6 speed.

Over heat warning two times, trans has been heating up to 220 city driving. But I live in MI. Should I do the bypass or the 150 replacement?

From what I understand, G.M. has a 150 degree thermostat for this transmission. Am I wrong?

what happens when you just remove the pill complete ? greetings.

How about the updated 150 thermostat gm makes

What is the better route to go in your opinion, transgo or superior surecool?

Flipping the pill did not work for me; still hitting 250 at times.

Geez, just swap it out with the 150 degree version already!

Why can’t you just get rid of it and just run old school by sending the oil to a cooler and back to the trans, heat is the worse enemy for a 6l80 and will kill the trans, you can buy a piece that does that exact thing and that’s what I’m doing and fitting a trans go shift kit, may do the trans go reprogramming kit if needed
