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.

ML would be driving fine and then loss of power and hard shifting. Did not fix problem yet.
I'm still looking for a solution.
