6T75 Valvebody & Tehcm 

Love that AC Delco part choice and thanks for showing programming also as will come in handy.

It would be nice to see a video showing how the valve body causes gears to change

Somehow missed leaving a comment last time, great work as always Gary!

Thank you, Gary.

well done Gary, thanks a lot for this wonderful video, just a quick one please, which diagnostic tool is recommended for programming. thanks

stay safe

thank you great job

thank you GARY

Is any " heatsink paste " used between Tehcm and valvebody ? Thanks for your videos , I greatly appreciate , your " parts " naming ! I would LOVE to be able to " Print " a " Text " of some of your PROCESSES !

Hello Gary been watching a lot of your videos I know this is off topic for this video but What would be a good company to get a banner kit for a 42rle and would they have hard parts also. thank you so much very good videos in depth detail and explanation

Thanks for the great information tutorial video. You really help me out a lot. I have some bad pressure switches on this 6T75 Gen 1, 2012 Buick Enclave. I have a question. If I just replace the pressure switches, do I have to replace the solenoid filter plate if I don't touch it? Thanks again....👍👍

Good

Hi Gary! I have a question i hope you can help me. I took the transmission off and change the clutches and i put a refurbished tehcm. The tehcm is not programed yet. Should the truck start or i shouldn't start it until programed. The truck doesn't start only cranks i think the fuel pump doesn't work. Is it the conputer in limp mode and doesn't let ir start?

Hi Gary, I hope you're still around and thanks for your videos, they are very informative! Ok, so here's my question. QUESTION: Can anyone get the software to program the TEHCM, or is it only available to certain repair shops? I have a 2011 Traverse with 272,000 miles on it and the trans is a mess. Slow to go into reverse (2-3 seconds), wild clunk (especially when its cold) at take off and when letting up on the accelerator in lower gears like 1, 2 3. Sometimes won't shift up or down properly (seems like it gets stuck in 4th gear) when going up the mountains. I already changed the pressure switch membranes, mine were all fine though. My Mech told me I have valve codes indicating sticky valves, but he also told me he has to pull the engine to change the valve body, which I am calling BS on. It's not easy, but it can be done without pulling the engine. So I would like to change both the TEHCM and the Valve body, but I'll just go with the valve body if TEHCM programming requires a licensed mechanic or a dealer. The car is worth less than the part, so I need to keep the investment as low as possible. Mike H.

hey gary i have a 6t70 gen 2 on a 2014 cadillac srx luxury, i have very harsh downshifts alot of the time, also slip/flare from 2-3. also when im coming to a stop, but dont completely stop (maybe 8-10mph), then start accelerating again, theres a very bad hesitation then clunk into gear. i have no problems fixing the issue myself, just cant pinpoint the exact problem, do you have any ideas what could be wrong in there? i already bought a sonnax 3-5-r drumsaver to put in (havent done it yet), but debating weather or not to get a zip kit from sonnax also. any help is appreciated thanks!!
