(B) Hydraulic Checking
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 (see page G-53) 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).

• Engine speed : Idling speed
• Oil temperature : 40 to 60 °C
104 to 140 °F
(Reference)
• Turn to clockwise direction → Pressure is increased
• Turn to counterclockwise direction → Pressure is decreased
