DESCRIPTION AND OPERATION

Transmission Range Selection

(P) Park

There is no power flow through the transmission in the park position. The parking pawl locks the output shaft (7060) to the case, preventing the vehicle from rolling. The engine can be started in the park range. Also, the vehicle gearshift lever (7210) must be in the park position before the ignition key can be removed.

(R) Reverse

The reverse gear position enables the vehicle to be operated in a rearward direction.

(N) Neutral

As in the park position, there is no power flow through the transmission in the neutral position. However, the vehicle's wheels are free to move because the output shaft is not held by the parking pawl. The engine may be started in the neutral position, but the key cannot be removed.

(D) Drive

Drive is the normal gearshift lever position for most driving conditions. This position provides automatic upshifts and downshifts through all three gears and maximum fuel economy during normal operation.

(2) Manual 2

Selection of the second gear position with the vehicle in a stationary position will allow only second gear to operate (no upshifting or downshifting will occur). If (2) position is selected at normal road speed, the transmission will downshift to second gear and stay there.

(1) Manual 1

Selection of the manual low position with the vehicle stationary will allow only first gear operation, and the vehicle will not upshift from this position. If this position is selected at normal road speed, the transmission will initially downshift into second gear, then downshift into first gear when the vehicle speed falls below approximately 32 km/h (20 mph).

The manual low position will provide engine braking, making it especially useful for descending steep grades.
