Anyway the car started right up afterwards but it is running kind of rough and the VSC light popped on. I'll give it a couple of days to dry out good and see what happens.

I just recently had my lower pan resealed. Had a slow seep. $150.00 Worth every penny.

The neutral safety switch is in the box attached to the AT and water is passing through there when the engine is washed by plenty of water with chemicals. The box is originally waterproofed but an aged box tends to loose the good capability of it and also some chemicals damage the sealing.

Funny, I power washed my engine twice and hit every last corner with no issue. Guess I won't press my luck any further after this thread.

I say use a Fel-Pro gasket, then you won't accidentally squeeze the excess into your transmission or oil pan!
