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 diagnosed and i'm waiting for an estimate to repair.
I was told by my mechanic that I have a transmission leak and if the fluids gets into the electrical connector. May caused major problems with a high expense.
