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 @ position while depressing the brake pedal-
Depress the accelerator pedal, and release it suddenly. The engine should not stall.
2. Repeat same test in E position.
3. Test drive the vehicle on a flat road in the @ 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.
-1. Remove the TCM (see page 14-52).-2. Set the digital multimeter to check voltage between 84 (+) terminal and A13 or A26 (-) terminal for the throttle posi-
tion sensor.

4. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shitt from E position to E position.
The vehicle should immediately begin slowing down from engine braking.
CAUTION: Do noi shitt lrom I or $ position to E or E position 8t speeds over l0o mph (160 km/h); you may
damage the transmission.
5. Check for abnormal noise and clutch slippage in the following positions,
E {1st Gear} Position-1. Accelerate from a stop at fullthrottle. Check that there is no abnormal noise or clutch slippage.-2. Upshifts should not occur with the shift lever in this position.
E (2nd Gear) Position-1. Accelerate from a stop atfull throttle. Check that there is noabnormal noiseorclutch slippage.-2. Upshifts and downshifts should not occur with the shift lever in this position.
E (Reverse) Position
Accelerate from a stop at tull throttle, and check for abnormal noise and clutch slippage.
6. Test in E (Parking) Position
Park vehicle on slope {app.ox. 16'}, apply the parking brake, and shift into E position. Release the brake; the vehicle
should not move.
