What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Rocket Man]

Thanks, Doug. I couldn't get that bolt in the center out, it just spins. And pulling on the white connector only yielded ~3/8" of movement. Didn't want to FUBAR it, so went a different direction.

Yeah I just spliced into the gray dome light wire in that connector. Soldered, heat shrink. Done.

Installed a new interior ambient air temp sensor in the headliner above the driver, fixed a persistent rattle under the dash near the windshield, and installed a new daylight sensor in the dash.

Some of the easiest and least-greasy fixes I've ever done on our cars. Satisfying.

Makes me wonder what brand they’re using. Not sure if there are aftermarket ones but that wouldnt make me feel real comfortable.

I assumed he meant TCM, transmission control module. Wes?

 

[Rocket Man]

TEHCM?

techm it has all the solenoids and crap in it, not like the 4l60's where they are right there under the pan, this is a whole module

The 4l60’s have a TCM, transmission control module, built into the Engine Control Module, under the hood. It’s not even a separate controller, and when we get a tune it’s just one file- ECM/TCM file all in one. I knew the 6L80’s had a separate controller but didn’t know it’s actually a Transmission Electro- Hydraulic Control Module that has not just the electronic brain but as GM states : “ TEHCM combines the function of a TCM with valve body solenoids, integrated electronic and hydraulic components, pressure and temperature switches, filter plate and an upgraded lead frame - all in a single unit.”

He could also try pulling the lower part of the seat out and tucking that moving blanket in and around the seat as a temp fix. The Carhartt cover material should be thick enough to protect against his nails. Worst case scenario--rear lower seats are cheap in the junkyards.

I tried moving blanket, but it lasts for 1 hour on long trips. Once he starts moving back & forth, it comes off. I was thinking to attach it permanently, but it gets so nasty, dirty and stinky eventually and has to come off for cleaning.

I might look in to these Carhartt covers. For now, the lower portions of the seats already destroyed, and actually, nobody but the dog rides there, so it is a problem for the future.

Ordered these.

I’ll probably be busy driving. You know, being safe and all!
I’ll try though.

Did a oil change today and switched to wix filters vs ac delco pf46E’s. Pretty sure I had 2 fail after 2500 miles with the lower oil pressure problem that there is a TSB out for. Always ran valvoline synthetic blend.
