Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
  • Raise the vehicle securely using jack stands to access the transmission.
2. Inspect and Replace Transmission Range Sensor

  1. Locate the Transmission Range Sensor:

    • The sensor is typically mounted on the transmission housing. Refer to the service manual for precise location.

  2. Disconnect the Electrical Connector:

    • Carefully unclip and remove the electrical connector from the TRS.

  3. Remove the Old Sensor:

    • Use a socket set to remove the bolts securing the sensor to the transmission.
    • Gently pull the sensor away from the transmission.

  4. Install the New Sensor:

    • Position the new transmission range sensor in place.
    • Secure it with bolts to the manufacturer’s specified torque (typically around 8-12 ft-lbs).
    • Reconnect the electrical connector ensuring a secure fit.
3. Fluid Check and Replacement

  1. Check Transmission Fluid Level:

    • Remove the transmission dipstick and wipe it clean.
    • Reinsert and remove again to check the fluid level. If low, add the manufacturer-recommended transmission fluid.

  2. Replace Fluid if Necessary:

    • If the fluid is dark or smells burnt, perform a transmission fluid change.
    • Drain the old fluid, replace the filter if applicable, and refill with new fluid.
4. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use the OBD-II scanner to clear the P0708 code from the vehicle’s computer.
