* Low & Reverse Brake is released when the vehicle speed is over 7Km/h (5 MPH).
Stall test procedure in D1 and reason
Procedure
- Warm up the engine
- After positioning the select lever in "D", depress the foot brake pedal fully. After that, depress the accelerator pedal to the maximum
* The slippage of 1st gear operating parts can be detected by stall test in D
Reason for stall test
- If there is no mechanical defaults in A/T, all slippage occurs in the torque converter.
- Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel's lock.
- If 1st gear operating part has faults, input speed revolution will be out of specification.
- If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is required.
- 5. Is "STALL TEST" within specification?
YES
- Go to "SIGNAL CIRCUIT INSPECTION " procedure.
NO
- Go to "COMPONENT INSPECTION " procedure.
CAUTION:- Do not let anybody stand in front of or behind the vehicle while this test is being carried out.
- Check the A/T fluid level and temperature and the engine coolant temperature.
- Fluid level: At the hot mark on the oil level gauge.
- Fluid temperature : 176°F ~ 212°F (80~100°C).
- Engine coolant temperature : 776°F ~ 212°F (80~100°C).
- Chock both rear wheels (left and right).
- Pull the parking brake lever on with the brake pedal fully depressed.
- The throttle should not be left fully open for more than eight seconds.
- If carrying out the stall test two or more times, move the select lever to the "N" position and run the engine at 1,000 RPM to let the A/T fluid cool down before carrying out subsequent tests.
