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.
Do not let anybody stand in front of or behind the vehicle while this test is being carried out
1. Check the automatic transmission fluid level and temperature, and the engine coolant temperature.
a. Fluid level : At the HOT mark on the oil level gauge
b. Fluid temperature : 80~100°C (176~212°F)
c. Engine coolant temperature : 80~100°C(176~212°F)
2. Prevent all the wheels from moving during the test.
3. Pull the parking brake lever up, with the brake pedal fully depressed.
4. Start the engine.
