The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

    Just had the transmission control module replaced by the dealer. Wasn't cheap, $955.00 including parts and labor.

    I had the same problem with the TCM. I had the conductor plate replaced and the TCM was cleaned of all oil. After that, the transmission worked fine but the ESP, ABS, SRS, and BAS lights continue to stay on. The vehicle is in the shop now (again) to correct this problem with the malfunctions.
