Solution
1. Preparation
  • Gather tools and parts.
  • Ensure the vehicle is parked on a level surface.
  • Disconnect the battery for safety.

Tools Required:

  • OBD-II scanner
  • Socket set
  • Multimeter
  • Transmission fluid
  • Torque wrench
  • Fluid catch pan
2. Fluid Inspection and Replacement

  1. Check Transmission Fluid:

    • Remove the transmission dipstick and wipe it clean.
    • Insert the dipstick back and then remove it again to check fluid level.
    • If low, add the correct type of transmission fluid as specified in the owner’s manual.

  2. Fluid Change:

    • Place a fluid catch pan under the transmission pan.
    • Remove the transmission pan bolts using a socket wrench.
    • Allow old fluid to drain completely.
    • Clean the pan and replace the filter if applicable.
    • Reinstall the transmission pan with new gasket and torque bolts to manufacturer specifications.
3. TCM Inspection

  1. Check TCM Connections:

    • Locate the TCM, usually near the transmission.
    • Inspect the electrical connectors for corrosion or damage.
    • Reconnect securely.

  2. Test TCM Output:

    • Using a multimeter, measure the voltage at the TCM output pins while the vehicle is in "Run" but not started.
    • Compare readings to specifications in the service manual.
4. Reconnect Battery and Test
  • Reconnect the battery terminals securely.
  • Start the engine and check for the check engine light.
  • Attempt to shift through the gears to ensure proper engagement.
