    Did you resolve the problem? I am wondering if chaffing of wires on your Power train controller area network (PT-CAN) would be causing that. I would think that electrical harness that feeds the powers , grounds and CAN lines to transmission might be chaffing. I would be looking along left side of transmission for chaffing and also around the harness brackets between the fuel module in front of or near air compressor. I have found a mirror with a telescoping handle is helpful with inspecting where the harness wraps around the top at the left of transmission. Curious if you were getting CAN communication faults.
