The document provides technical information on the 6L80/90 transmission including: 1) The pressure test port is located behind the bell housing on the passenger side. Pressure should be 45-80 psi at idle and up to 300 psi in gear at wide open throttle. 2) The transmission control module (TCM) is integrated into the valve body/solenoid assembly. 3) In the event of a failure, the transmission will default to 3rd gear if between 1st and 3rd, and 5th gear if between 4th and 6th.
