Transmission May Leak Fluid and Damage Control Module on Mercedes-Benz CLS55 AMG

The electrical connector at the automatic transmission may leak fluid into the wiring harness. If not repaired, the oil will migrate through the wiring harness and damage the transmission control module. At that point, a new harness and control module may be necessary to correct this problem.
