Torque Converter Stall Test: Notes

This test measures the maximum engine speed when the selector lever is in 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 transaxle.

1. Check the automatic transaxle 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
2. Chock both rear wheels (left and right).
3. Apply the parking brake lever with the brake pedal fully depressed.
4. Start the engine.
5. 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 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 RPM to let the automatic transaxle fluid cool down before carrying out subsequent tests.

     Standard value stall speed: 2,100 ~ 2,900 RPM

   • Move the selector lever to the R position and carry out the same test again.

     Standard value stall speed: 2,100 ~ 2,900 RPM
