Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, rags.
Ensure the vehicle is on a level surface and safely elevated with jack stands if necessary.
Disconnect the battery negative terminal for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick/fill port and wipe it clean, then reinsert to check fluid level.
3. If low, add the appropriate transmission fluid according to the owner’s manual specifications.
4. If fluid appears burnt or contaminated, proceed to replace the transmission fluid.
  - Fluid Replacement:
    - Drain the old fluid by removing the transmission pan (ensure to have a drain pan ready).
    - Replace the transmission filter if applicable.
    - Reinstall the transmission pan with a new gasket, torquing to manufacturer specifications.
    - Refill with new transmission fluid using the funnel through the dipstick or fill port.

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 securing bolts and carefully take out the sensor.
4. Install the new sensor, securing it with bolts to the specified torque.
5. Reconnect the electrical connector and ensure it clicks in place.

4. Check and Adjust Shift Linkage

Sub-steps:
1. Inspect the shift linkage for any signs of wear or misalignment.
2. Adjust the linkage according to the service manual specifications to ensure proper engagement.
3. Test the movement of the shift lever to confirm smooth operation.
