Torque Converter Stall Test
This test measures the maximum engine speed when the selector lever is at the D or R position. The torque converter stalls to test the operation of the torque converter, starter motor, one-way clutch operation, the holding performance of the clutches, and brakes in the transmission.
CAUTION:
Do not let anybody stand in front of or behind the vehicle while this test is being carried out.
- Check the automatic transmission fluid level and temperature and the engine coolant temperature.
- Fluid level : At the HOT mark on the oil level gauge
- Fluid temperature: 80-100°C
- Engine coolant temperature: 80-100°C
- Check both rear wheels (left and right).
- Pull the parking brake lever on with the brake pedal fully depressed.
- Start the engine.
- Move the selector lever to the D position, fully depress the accelerator pedal and take a reading of the maximum engine speed at this time.
CAUTION:
- The throttle should not be left fully open for any more than eight seconds.
- If carrying out the stall test two or more times, move the selector lever to the "N" position and run the engine at 1,000 r/min to let the automatic transmission fluid cool down before carrying out subsequent tests.
Standard value
Stall speed: 2000-2600 RPM
- Move the selector lever to the R position and carry out the same test again.
Standard value
