Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back and remove it again to check fluid level; top off if low.
3. If fluid is dark or burnt, proceed to replace it.
4. Place a drain pan under the transmission pan and remove the transmission pan bolts.
5. Allow old fluid to drain completely; clean the pan and replace the filter if applicable.
6. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically 8-12 ft-lbs).
7. Refill the transmission with the appropriate type and amount of fluid (refer to manufacturer specifications).

3. Inspect and Replace Transmission Range Sensor

Sub-steps:
1. Locate the transmission range sensor on the transmission housing.
2. Disconnect the electrical connector from the sensor.
3. Remove the mounting bolts and take out the old sensor.
4. Install the new sensor, tightening the bolts to manufacturer specifications.
5. Reconnect the electrical connector.

4. Clear Error Codes

Sub-steps:
1. Reconnect the battery’s negative terminal.
2. Use the OBD-II scanner to clear any stored error codes.
3. Start the vehicle and check if the problem persists.
