Transmission Line Pressure

The following charts provide the mainline pressure readings for all the variations of TCI transmissions. These readings are obtained by utilizing a 300 psi gauge in 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.

Simply click on the transmission you are interested in and scroll down to quickly locate the appropriate pressure chart for your needs.
