Transmission Line Pressure Specifications

The following charts provide the mainline pressure readings for all of the various TCI® transmission models. These readings can be obtained by attaching a 300 psi fluid pressure gauge to the appropriate pressure port on the transmission, and running the engine at 2000 rpm.

These pressure readings provide a valuable source of information when troubleshooting transmission problems or as a system check after rebuilding a transmission or installing a TCI® valve body.
