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.Google+

had a 2001 C320 with same trans problem. Cost $1400 for a new module. I sold the car not long after because I was tired of the repair ongoing repair expenses.
is the control module inside the transmission or on the outside of it.
