Have Transmission Questions? Ask a Mechanic for Answers ASAP
I would be suspicious of the C0055 code causing the problem. I have seen the ABS module take down the transmission control module communication/ power supply to the transmission control module.
Does the speedometer and odometer work?
1. Disconnect the Transmission Control Module (TCM). Turn the key on and on the Clear connector verify battery voltage to the Orange wire at pin 3 and the Pink wire at pin 4.2. Verify a good ground on the same connector at pins 1 and 5. Both wires are Black/White.3. Establish communications with the EBCM. Locate and ground the Yellow wire at pin 30 in the Clear connector at the TCM.4. Within 3 - 10 seconds after grounding, expect the scanner to go to "No Communications". If it does, replace the TCM.
Here is the connector Pin view:
The TCM is in front of the battery box.
Please let me know if you would still like help with this problem.
