Upshift

Downshift

3. Accelerate to about 35 mph (57 km/h) so the transmission is in 4th, then shift from position to position. The vehi-

cle should immediately begin slowing down from engine braking.

CAUTION: Do not shift from position to position at speeds over 76 mph (123 km/h) or from position to posi-

tion at speeds over 45 mph (73 km/h); you may damage the transmission.

4. Check for abnormal noise and clutch slippage in the following positions.

(1st Gear) Position

Accelerate from a stop at full throttle. Check that there is no abnormal noise or clutch slippage.

Upshifts should not occur in this position.

(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 in this position.

(3rd Gear) Position

Shift to position, then start the car in 1st or 2nd gear and shift to 3rd gear with the shift switch.

Accelerate at full throttle. Check that there is no abnormal noise or clutch slippage.

(Reverse) Position

Accelerate from a stop at full throttle, and check for abnormal noise and clutch slippage.

5. Test in (Parking) Position.

Park the vehicle on a slope (approx. 16°) and apply the parking brake, then shift into position. Release the brake; the
