- Allow fluid to drain completely into a container.
Step 2: Replace the transmission filter:
- Remove the old filter and install a new one according to the manufacturer's specifications.
Step 3: Clean the pan:
- Use a clean rag to wipe the inside of the pan and the magnet (if present).
Step 4: Reinstall the pan:
- Torque the pan bolts to the manufacturer’s specifications.

3. Fluid Refill

Step 1: Refill transmission fluid:
- Use a funnel to add the correct type of transmission fluid as specified in the owner’s manual.
Step 2: Check fluid level:
- Start the engine and shift through all gears, checking fluid level again and adding as necessary.

4. Final Checks
