Reinstall the dipstick or fill plug securely.

3. Inspect and Repair Electrical Connections

Tools Required: Multimeter, screwdrivers, wire brush.
Locate the transmission control module (TCM) and disconnect it.
Clean the connectors with a wire brush if corrosion is present.
Use a multimeter to check for continuity and proper voltage at the TCM harness.
Reconnect the TCM and ensure all connections are tight.

4. Repair or Replace Shifter Linkage

Tools Required: Socket set, pliers, replacement parts.
Inspect the shifter linkage for any signs of damage or wear.
If damaged, remove the shifter assembly using a socket set.
Replace with new parts as needed and reinstall the assembly, ensuring proper alignment.

5. Update Transmission Control Software

Tools Required: OBD-II scanner with programming capability.
Connect the OBD-II scanner to the vehicle and access the transmission control module.
