46RE Shifting Issues

The temp sensor is part of the pressure transducer. I never saw any problems with oil in the connector to the trans. That is an issue on Gm/allison trans. I did run into one ECM that could not control the solenoid correctly but that is pretty rare. There is a pressure test port on the passenger side right at the joint between the main case and the OD unit. When working correctly you should get 1 psi per mph that goes up smoothly and matches what the computer commands.
