Shifts fine when cold and has sat, but when i get a mile down the road it goes into limp mode, filter was changed not long ago and speed sensor just replaced. Was driving fine till i washed the motor and underneath truck. I just dont see the sensors in the trans going out right after washed it. Also added seafoam trans additive month before problem.
