Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, transmission fluid dipstick.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Fluid Check and Replacement

Remove the transmission dipstick: Wipe it clean and reinsert it to check fluid level.
Inspect fluid condition: If the fluid is dark or burnt, it needs to be replaced.
Drain old fluid: Place a fluid catch pan under the transmission pan, remove the drain plug, and allow fluid to fully drain.
Replace the transmission filter: Remove the transmission pan by unscrewing bolts, carefully detach it, and replace the filter as per manufacturer specifications.
Reinstall the transmission pan: Clean the mating surfaces, apply new gasket material if needed, and torque the bolts to the specified value (usually around 8-12 ft-lbs).
Refill with new transmission fluid: Use the manufacturer-recommended fluid type, adding fluid through the dipstick tube until the appropriate level is achieved.

3. Electrical Check

Inspect wiring harness: Look for any frayed or damaged wires connected to the transmission control module.
Test the transmission range sensor: Use a multimeter to verify proper voltage and resistance at the sensor; replace if faulty.

4. Test Drive

Conduct a test drive: Monitor transmission behavior under various conditions (acceleration, deceleration, and shifting).
Recheck fluid level: After the test drive, recheck the transmission fluid level and top off as necessary.
