Hydraulic Test

Measure the line pressure.

NOTE:
- Do the test at normal operation 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 doing the test.
- Be careful to prevent SST's hose from interfering with the exhaust pipe.

1. Warm up the ATF.
2. Remove the test plug on the front left side of the transmission case and connect SST
(See the location to connect SST)
SST 09992-00095 (09992-00231, 09992-00271)

HINT: The connection of SST will become easier by moving LH side heat insulator aside.

3. Chock the 4 wheels.
4. Fully apply the parking brake.
5. Start the engine and check idling speed.
6. Keep your left foot pressing firmly on the brake pedal and shift into D position.
7. Measure the line pressure when the engine is idling.
8. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when engine speed reaches stall speed.

NOTE: Release the accelerator pedal and stop test if the wheels begin to rotate before the engine speed reaches the specified stall speed.

9. In the same manner, do the test in R position.




Specified line pressure:
If the measured pressures are not up to the specified values, check the shift solenoid valve SLT and retest.
