Solution
1. Preparation
  • Gather tools (OBD-II scanner, socket set, multimeter, fluid pump).
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Check and Top Off Transmission Fluid
  • Remove the transmission dipstick and check the fluid level.
    • If low, use a fluid pump to add the manufacturer-recommended transmission fluid until the correct level is reached.
  • Inspect the fluid condition:
    • If burnt or contaminated, proceed to fluid change.
3. Change Transmission Fluid and Filter (if necessary)
  • Remove the transmission pan using a socket set.
  • Replace the transmission filter if applicable.
  • Clean the pan and magnet, then reinstall the pan with a new gasket.
  • Fill the transmission with the appropriate fluid type (consult owner’s manual for specifications).
4. Test the Overdrive Switch
  • Remove the gear shifter cover to access the overdrive switch.
  • Disconnect the switch and test it with a multimeter for continuity.
    • If faulty, replace the switch with a new one.
5. Inspect Transmission Control Module (TCM)
  • Locate the TCM and inspect the wiring and connectors for damage.
  • If the TCM is suspected to be faulty, consider reprogramming or replacing it.
  • Reconnect the battery terminal once all checks and repairs are completed.
