Torque Converter Stall Test

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.

• 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
• Prevent all the wheel from moving during the test.
• Pull the parking brake lever up, 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 five 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 transaxle fluid cool down before carrying out subsequent tests.
• Move the selector lever to the "R" position and carry out the same test again.
