Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Fluid Inspection:

  • Remove the transmission dipstick (if equipped) and check fluid level and condition.
  • If fluid is low, add the recommended transmission fluid per the manufacturer's specifications.

• Fluid Replacement (if necessary):

  • Raise the vehicle securely on jack stands.
  • Place a drain pan under the transmission pan; remove the transmission pan bolts.
  • Allow old fluid to drain completely, then clean the transmission pan and replace the filter if applicable.

  • Fill the transmission with new fluid through the dipstick tube until the level is correct.

3. Check and Repair Wiring and Connectors

• Visually inspect the wiring harness leading to the TCM for any signs of fraying or disconnection.
• Clean and reseat any corroded connectors.
• Replace any damaged wiring or connectors as needed.

4. Test and Replace Transmission Control Module

• Testing:

  • Use a multimeter to check the voltage and ground signals at the TCM.

• Replacement:

  • If the TCM is faulty, carefully disconnect it and remove it from its mounting.
  • Install the new TCM, ensuring all connections are secure.
  • Reconnect the negative battery terminal.

5. Recalibrate Transmission Range Sensor
