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.
- Warm up the ATF.
- Remove the test plug on the front left side of the transmission case and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
- Fully apply the parking brake and chock the 4 wheels.
- Start the engine and check idling speed.
- Keep your left foot pressing firmly on the brake pedal and shift into D position.
- Measure the line pressure when the engine is idling.
- Depress 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:
SPECIFIED LINE PRESSURE SPECIFICATIONCondition D position kPa (kgf/cm2 , psi) R position kPa (kgf/cm2 , psi) Idling 395 - 455 (4.0 - 4.6, 57 - 65) 0 Stall 1,200 - 1,360 (12.2 - 13.8, 174 - 196) 1,655 - 1,960 (16.9 - 19.8, 240 - 282)
If the measured pressures are not up to the specified values, recheck the throttle cable adjustment and retest.

PROBLEM AND POSSIBLE CAUSE CHART
| Problem | Possible cause |
|---|---|
| If the measured values at all positions are higher |
|
| If the measured values at all positions are lower |
|
| If pressure is low in the D position only |
|
| If pressure is low in the R position only |
