HYDRAULIC TEST
Measure the line pressure.
NOTE:
- Do the test at normal operation fluid temperature 70-80 °C (158- 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 transmission case front left side and connect SST.
SST 09992-0095 (09992-00231, 09992-00271)
3. Fully apply the parking brake and chock the 4 wheels.
4. Start the engine and check idling speed.
5. Keep your left foot pressing firmly on the brake pedal and shift into D position.
6. Measure the line pressure when the engine is idling.
7. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when engine speed reaches stall speed.
8. In the same manner, do the test in R position.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
