Hydraulic Pressure Tests

HYDRAULIC PRESSURE TEST





1. Check the A/T fluid level and temperature. Check engine coolant temperature.
- A/T fluid level: "HOT" mark on the dipstick
- A/T fluid temperature: 70 - 90°C (158 - 194°F)
- Engine coolant temperature: 80 - 100°C (176 - 212°F)
2. Jack up the vehicle so that the wheels are free to turn.





3. Connect the special tools (2,942 kPa (427 psi) oil pressure gauge [MD998330] and adapters [MD998332, MD998900]) to each pressure discharge port.

NOTE:
2ND: Second brake pressure port
UD: Underdrive clutch pressure port
LR: Low-reverse brake pressure port
DA: Torque converter apply pressure port
DR: Torque converter release pressure port
PV.- Reverse clutch pressure port
OD: Overdrive clutch pressure port

4. 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.





5. If a value is outside the standard range, correct the problem while referring to the hydraulic pressure test diagnosis table.

STANDARD HYDRAULIC PRESSURE TEST





NOTE: If the torque converter pressure is measured, the engine speed should be 1,500 r/min or less.
