Testing Line Pressure TH-350
 

Where is the port to test line pressure on a TH-350? With my car in low gear it will move forward 15 ft., then when I stop it won't move again. The engine just revs but the car doesn't move. Went through the shifter adjustment and the fluid doesn't smell or look burnt. Thanks.

Right side of case (passenger side), near tail housing; there is a hex head 1/4 npt plug.

Between the modulator and the servo?

Right side of TH350 case.

Rear port is main line pressure. You will see pressure here in all gears for most valve body configurations. Some race-only valve bodies may not have pressure at this port or the others
Middle port is 2nd gear pressure
Front port is third gear pressure
