Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Inspect Fluid Level
- Remove the transmission dipstick and wipe it clean.
- Insert the dipstick back and remove it to check fluid level; it should be between the "FULL" and "ADD" marks.
Replace Fluid (if necessary)
- Using a fluid pump, remove the old transmission fluid through the dipstick tube.
- Refill with the recommended transmission fluid type (consult owner's manual).
- Check for leaks after filling.

3. Inspect and Replace Transmission Range Sensor

Locate the Sensor
- Find the transmission range sensor on the transmission housing.
Remove the Old Sensor
- Disconnect the electrical connector.
- Remove the mounting bolts using a socket set.
Install the New Sensor
- Position the new sensor in place, secure it with bolts, and reconnect the electrical connector.

4. Test Drive and Adjust

Reconnect the Battery
- Ensure all connections are secure before reconnecting.
Test Drive
- Take the vehicle for a short drive to monitor any improvements in shifting.
Check for Error Codes Again
- After the test drive, scan for any new error codes that may have appeared.
