Anyone know what the thread size and pitch is for the pressure taps on the side of the transmission case? My car has this "morning sickness issue", but it is not significant and has not caused too much grief for me yet.
I want to do a line pressure test as well as a forward clutch pressure test to gather some data on this phenomenon. Past experience tells me ABSOLUTELY NO parts changing in old high mileage transmissions. If its acting up, its time for a rebuild.
