Line Pressure Test

MEASURE LINE PRESSURE
NOTICE:
- Do the test at normal operating fluid temperature 50 - 80 °C (122 - 176 °F).
- The line pressure test should always be carried out in pairs.
- One technician should observe the conditions of the wheels or wheel stoppers outside the vehicle while the other is doing the test.
- Be careful to prevent the oil pressure gauge hose from interfering with the exhaust pipe.
- Warm up the transmission fluid.
- Remove the test plug on the transmission case left side and connect the oil pressure gauge SST 09992-00094.

HINT: Connecting the oil pressure gauge will be made easier be moving LH side heat insulator aside.

- Fully apply the parking brake and chock the 4 wheels.
- Start the engine and check idling RPM.
- Keep your left foot pressed firmly on the brake pedal and shift into D position.
- Measure the line pressure when the engine is idling.
- Press the accelerator pedal all the way down.
- Quickly read the highest line pressure when engine speed reaches stall speed.
- In the same manner, do the test in R position.




SPECIFIED LINE PRESSURE
If the measured pressures are not up to specified values, recheck the throttle cable adjustment and do a retest.
