Tools Required: Socket set, fluid container, funnel.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing all bolts (torque specification for reinstallation: typically around 10-12 lb-ft).
2. Carefully detach the pan and discard the old filter.
3. Install the new filter according to the manufacturer's instructions.
4. Reinstall the transmission pan with a new gasket to prevent leaks.
Tools Required: Socket set, torque wrench, gasket scraper.

4. Inspect and Replace Solenoids (if needed)

Sub-steps:
