Under the hood next to the bulkhead on the left looking from the front of the car, you will find hot water pipes going into the heater unit. There is a valve with two wires going into it ( solenoid valve), it's stuck in the off position. Check for power, tap it , or change it. I had exactly the same prob. The valve is situated on one of the pipes, and is not easy to change. Hope this helps...

Problem Reported: Wire Connector on Transmission May Leak Fluid and Damage Control Module

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.
