- the parking pawl locks the output shaft to the case.
- the engine can be started.
- the ignition key can be removed.
Reverse
In the REVERSE position:
- the vehicle can be operated in a rearward direction, at a reduced gear ratio.
- engine braking will occur.
Neutral
In the NEUTRAL position:

- the output shaft is not held and is free to turn.
- the engine can be started.
Overdrive
Overdrive is the normal position for most forward driving.
The OVERDRIVE position provides:
- Automatic shifts.
- Apply and release of the torque converter clutch.
- Maximum fuel economy during normal operation.
Second Position
This position provides:
- Second gear start and hold.
- The torque converter clutch can apply and release.
- Improved traction and engine braking on slippery roads.
- Engine braking for descending steep grades.
First Position
If this position is selected at normal road speeds, the transmission will shift into second gear, then into first when the vehicle reaches a speed below approximately 45 km/h (28 mph).
This position provides:
- First gear operation only.
- Engine braking for descending steep grades.

Pinpoint Test D: LFC 15/DTC B 1887- Driver Air Bag Circuit Shorted to
Ground
Normal Operation
The restraints control module (RCM) checks for driver air bag circuit
shorts to ground by monitoring the
voltage of circuits 614 (GY/OG) and 615 (GY/WH) at pins 3 and 4. If the RCM
detects a short to
ground on either of these pins, it w ...
