Transmission Line
Pressure
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 pressue 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.
Simply click on the
transmission you are interested in, or scroll down to locate the
appropriate line pressure chart for your needs.
