Adam, I have access to diagrams thru Alldata. Are they good enough for what you need?

On edit: I hope those are what you were looking for. They are whats listed under the various control modules

Tom can you confirm if this is the 5 or 6 speed and which year truck?
Looking at transmission 3 and the colour and numbers for the TCC solenoid don't jive with what Mike L told me. Trying to diagnose a P0741 issue that usually only shows up when it gets to 5th gear. Changed the internal harness as the plug was leaking oil through the pins but still have the same problem. Pulling out my hair........:mad:

Geezus, you're asking me about something I posted 8 years ago?!? :hehe:
Im pretty sure they are for a 2003 truck, which I own. Id have no reason to spend the money on an alldata sub for an LBZ. Sorry Dale.

Yes this is for a 6 Speed, right out of the 2006 GM service manuals. Let me know if you need anything else.

That goes for anyone else reading this too

2007.5 lmm

I am looking for all of the ground locations for the LMM.

Bought a truck off of a guy who claimed it was all good. Its not! Had junk batteries so replaced them and it helped some of the codes.

But now it has the P0700 and cant decide what gear it wants to be in. But it doesn't do it all of the time. Well messing under the hood checking connections last night... it didn't start this morning, all the lights came on but just clicking :dontknow:

Hope its just a bad ground or broke wire! Any help would be Amazing!
