Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission drain plug or pan bolts to drain old fluid.
3. Inspect the transmission pan for metal shavings or debris; clean if necessary.
4. Replace the transmission filter if applicable.
5. Reinstall the drain plug or transmission pan with a new gasket and torque to manufacturer specifications.
6. Refill with new transmission fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Range Sensor (if faulty)

Sub-steps:
1. Locate the transmission range sensor; it is typically mounted on the side of the transmission.
2. Disconnect the electrical connector from the sensor.
3. Remove the mounting bolts holding the sensor in place.
4. Install the new range sensor and secure it with bolts.
5. Reconnect the electrical connector.

4. Test Throttle Body and Cable
