Stall Test
NOTE:
The object of this test is to check the overall performance of the transmission and engine by measuring the maximum engine speed at the "D" and "R" ranges. For STALL SPEED TABLE, See STALL SPEED SPECIFICATIONS Table. For CLUTCH AND BRAKE APPLICATION Chart, See Fig 1 .
- Chock front wheels. Mount an engine tachometer. Fully apply parking brake. Step down strongly on brake pedal with left foot. Start engine. Shift into "D" range. Step down fully on accelerator pedal with right foot. Quickly read highest engine RPM at this time.NOTE: Perform test with fluid at normal operating temperature.CAUTION: DO NOT perform this test for longer than 5 seconds.
- If engine speed is the same for both ranges but lower than specified value, then engine output may be insufficient or stator one-way clutch may not be operating properly.NOTE: If more than 600 RPM below the specified value, the torque converter could be at fault.
- If stall speed in "D" range is higher than specified, then front clutch may be slipping, one-way clutch No. 2 may not be operating properly or line pressure may be too low.
- If stall speed in "R" range is higher than specified, rear clutch may be slipping, brake No. 3 may be slipping or line pressure may be too low.
