Im positive that someone here knows the procedure on testing the transmission charge pump pressure. Where to tap in and what it should be. Thanks
Leak in lines going to brake or leaking past seals in brake assembly. Could use a porta power very carefully not to over pressurize brake piston. pump it until brake releases and see if it leaks down.
Is differential overfill?
Serial number? They made a change to the transmissions during production and the test port changes with the serial number.
