Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, replacement transmission fluid, fluid pump, transmission filter kit, clean rags, and safety gloves.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before starting any work on the transmission.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the transmission pan to drain the fluid completely.

3. Inspect and Replace Filter

Remove the old transmission filter if applicable.
Inspect the filter for metal shavings or debris; replace with a new filter if necessary.
Ensure the filter is seated properly before reassembling.

4. Clean Transmission Pan

Clean the transmission pan and magnet with a clean rag to remove any debris.
Inspect the gasket surface for damage; replace the gasket if needed.

5. Reassemble and Refill Transmission Fluid

Reinstall the transmission pan and tighten the bolts to the manufacturer’s specified torque (typically around 8-12 Nm).
Use a fluid pump to refill the transmission with the recommended type of transmission fluid (consult owner's manual for specifications).
Start the engine and allow it to warm up; check the fluid level and add as necessary.
