Road Test

ROAD TEST

NOTE: Warm up the engine to operating temperature (the radiator fan comes on).

1. Apply parking brake and block the wheels. Start the engine, then shift to N position while depressing the brake pedal. Depress the accelerator pedal, and release it suddenly. The engine should not stall.
2. Repeat same test in [D3] position.
3. Test drive the vehicle on a flat road in the N position. Check that the shift points occur at approximate speeds shown. Also check for abnormal noise and clutch slippage.

NOTE: Throttle position sensor voltage represents the throttle opening.

- Remove the TCM.




- Set the digital multimeter to check voltage between B4(+) terminal and A13 or A26(-) terminal for the throttle position sensor.




- Upshift: [D4] Position





- Upshift: [D3] Position





- Downshift: [D4] Position





- Downshift: [D3] Position





- Lock-up: [D4] Position





- Lock-up: [D3] Position

4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shift from [D4] position to [2] position.
The vehicle should immediately begin slowing down from engine braking.

CAUTION: Do not shift from [D4] or [D3] position to [2] or [1] position at speeds over 100 mph (160 km/h); you may damage the transmission.





5. Check for abnormal noise and clutch slippage in the following positions.
[1] (1st Gear) Position
Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage.
Upshifts should not occur with the shift lever in this position.
[2] (2nd Gear) Position
Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage.
Upshifts and downshifts should not occur with the shift lever in this position.
[R] (Reverse) Position
Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.

6. Test in [P] (Parking) Position
Park vehicle on slope (approximately 16°), apply the parking brake, and shift into [P] position. Release the brake; the vehicle should not move.
