I have a 2008 duramax that has a "service 4 wheel drive" with a P0880 code ..TCM Power input signal. The fuse for the TCM is good. Can anyone tell me what is going on, and what to check next. Where is the TMC located? Thanks for any help!!

Thanks for the reply! I cannot seperate the connector from the TCM. I have the locking lever over toward the radiator...but cannot seperate the two. Is there another lock? Don't want to bust it.....I live 20mi. from town! Should the ing. key be on to ck. the voltage? Can I drive it ? Thanks
