Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid pump, OBD-II scanner, transmission fluid dipstick.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent accidental electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. Using a funnel and fluid pump, add the appropriate transmission fluid (consult the owner’s manual for specifications).
3. Start the engine and let it idle while shifting through all gears to circulate the fluid.
4. Recheck the fluid level and add more if necessary until it reaches the correct level.
5. If the fluid smells burnt or has particles, proceed to drain and replace the fluid entirely.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan (if applicable) by loosening the bolts with a socket.
2. Carefully lower the pan and allow any excess fluid to drain out.
3. Remove the old transmission filter and install the new one, ensuring it is seated properly.
4. Clean the transmission pan and reinstall it, tightening the bolts to the manufacturer’s torque specifications.

4. Check Transmission Control Module

Sub-steps:
1. Inspect the wiring harness connected to the transmission control module for any signs of wear or damage.
2. If necessary, test the module with a multimeter to ensure it's functioning within specifications.
3. Reconnect any loose connections and clear any error codes using the OBD-II scanner.
