2007 Chevy avalanche - Lost comm with TCM
I recently had my Traction control light on and the display says service traction control and service stabilitrak. the only code that i am getting is U0101(lost communication with TCM). the truck seems to be in limp mode(shifts into forward and reverse but seems to only be in 3rd gear for froward). my scan tool will not communicate with the TCM.
Does anyone have a wiring diagram for the TCM/TCM plug. i want to check the ground/power/CAN BUS before replacing the TCM or bringing to a shop.
Thanks
