Line Pressure Test

MEASURE LINE PRESSURE
NOTICE:
- Perform 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 wheels or wheel stoppers outside the vehicle while the other is performing 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. SST 09992-00094

HINT: Connecting the oil pressure gauge will be made easier by 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, perform the test in R position.




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