Hydraulic Pressure Test: Notes
WARNING: This page is about a different variant/trim than selected.
CAUTION:
The transmission fluid temperature should be between 70-80°C (158-176°F) during the test.
- Check the transmission fluid level and temperature. Check engine coolant temperature.
- Transmission fluid level: "HOT" mark on the dipstick
- Transmission fluid temperature: 70-80°C (158-176°F)
- Engine coolant temperature: 80-100°C (176-212°F)
- Raise the vehicle so that the wheels are free to turn.
- Connect the special tools (3.0 MPa (427 psi) oil pressure gauge [MD998330] and joint [MD998331, MD998900] and adapter [MD992127]) to each pressure discharge port.NOTE: DR: Torque converter output pressure port
PRI: Primary pressure port
PL: Line pressure port
FWD: Forward clutch pressure port
REV: Reverse brake pressure port - Restart the engine.
- Check that there are no leaks around the special tool port adapters.WARNING: For safety, operators must not stand in front of and at the rear of the vehicle during this test.
- Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.
- If the pressure is not within the standard value, stop the engine and refer to the hydraulic pressure test diagnosis table.
- Remove the O-ring from the port plug and replace it.
- Remove the special tool, and install the plugs to the hydraulic pressure ports.
- Start the engine and check that there are no leaks around the plugs.
