WRONG, the OP said he has fluid in the wiring harness... Nothing 'basic' will return this car to 'normal'. Although it is a good idea to suppliment/check the engine/battery grounds, this isn't going to help this member fix the car until his harness is replaced at the TCU and probably even a replacement TCU installed. THEN that connector at the transmission needs to be fixed BEFORE the car can be returned to service since it is allowing transmission fluit to 'wick up' the cable. Much more needing care here besides a 'phantom' grounding issue...
