This test measures the maximum engine speed at the time the torque converter stalls with the selector lever in the D or R position. With this test, the holding abilities of the clutch and brake that are incorporated in the transaxle can be checked.warning | For safety, operators must not stand in front of and at the rear of the vehicle during this test. |
1. Check the transmission fluid level, transmission fluid temperature, and engine coolant temperature.- Transmission fluid level: In the "HOT" range on the oil level gauge
- Transmission fluid temperature: 70 to 80°C (158 to 176°F)
- Engine coolant temperature: 80 to 100°C (176 to 212°F)
note | Use scan tool (M.U.T.-III) to measure the transmission fluid temperature. |
2. Raise the vehicle.
3. Pull the parking brake lever, and then fully depress the brake pedal.
4. Start the engine.
5. caution | - Do not maintain the WOT condition for 5 seconds or longer.
- When continuing the stall test, make sure that the fluid temperature does not exceed 80°C (176°F). If the transmission fluid temperature exceeds 80°C (176°F), run the engine at around 1,000 r/min for 1 minute or longer to lower the transmission fluid temperature to 80°C (176°F) or less.

Move the selector lever to the D range and fully depress the accelerator pedal. Quickly read the maximum engine speed at this time.
Standard value - Stall speed: 2,400 - 2,900 r/min
6. Move the selector lever to the R range, and then repeat the previous step.Standard value - Stall speed: 2,400 - 2,900 r/min
