Checking GST System Pressure
1. Start the engine and warm up the transmission fluid, and then
stop the engine.
2. Remove the GST system pressure checking port (1) plug (PT
1/8) on the GST valve (2).
3. Install the GST valve adaptor (Refer to "8. SPECIAL TOOLS" at
"G. GENERAL" section) to checking port (1), and then install the
threaded joint, cable and pressure gauge.
4. Start the engine and set the idling speed. Set the shift levers to
"Neutral".
5. Measure the pressure.
6. If the measurement is not within factory specifications, adjust
the pressure reducing valve adjustor (4) on the regulating valve
assembly (5).
