Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi Good morning Im David,,,about the p0700 code: The ecm has turned the cel light on after receiving a message from the tcm that a dtc has set in the tcm. you will need a full function scan tool to read the dtc that has set in the tcm.
the u101 is a failed communication with the tcm will cause the p0700 to set.first I would check all of the connection plugs to the transmission, . It sounds like you might have a loose or broken wire. but the jacket is not broken. you may have to take it to the dealer and get a replacement harness just the one for the control moduleYou will need the tcm codes to continue any diagnosis.You can check the condition of the fluid. Is it brown, smelly and burned, or clean and bright red?
do you still need assistance?
