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-64) 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).
Condition
• 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

Checking Regulating Valve Setting Pressure
1. Start the engine and warm up the transmission fluid, and then
stop the engine.
2. Remove the pressure checking port (3) plug (PT 1/8).
3. Install the adaptor
"7"
to checking port (3) and then install the
adaptor
"D"
, the threaded joint, cable and pressure gauge.
4. Start the engine and set the maximum engine speed. Set the
shift levers to
"Neutral"
.
5. Measure the pressure. (Do not turn the steering wheel.)
6. If the measurement is not within factory specifications, adjust
the regulating valve adjustor (2) on the regulating valve
assembly (1).
Condition
• Engine speed
Maximum
• Oil temperature
40 to 60 °C (104 to 140 °F)
