- Carefully lower the pan and allow the old transmission fluid to drain into a suitable container.
Safety Warning: Ensure the fluid is cool before handling.

3. Remove Transmission Filter

Sub-steps:
- Once the fluid has drained, locate the transmission filter, which is typically secured with clips or bolts.
- Remove the retaining clips or bolts using the appropriate socket size.
