Measure Stall Speed

2. Mount an engine tachometer.
3. Fully apply the parking brake.
4. Step down strongly on the brake pedal with your left foot.
5. Start the engine.

Stall speed: 2250 ± 150 rpm
8. Perform the same test in the "R" range.

Evaluation
1. If the engine speed is the same for both ranges but lower than the specified value:
^ Engine output is insufficient.
^ Stator one-way clutch is not operating properly.

NOTE: If more than 600 rpm below the specified value, the torque converter could be faulty.

2. If the stall speed in "D" range is higher than specified:
^ Line pressure too low
^ Forward clutch slipping
^ No.2 one-way clutch not operating properly
3. If the stall speed in "R" range is higher than specified:
^ Line pressure too low
^ Direct clutch slipping
^ No.3 brake slipping
4. If the stall speed in the "R" and "D" ranges are higher than specified:
^ Line pressure too low
^ Improper fluid level
