3. Remove the old transmission filter and install the new one, ensuring it is seated properly.
4. Reinstall the transmission pan with a new gasket and torque the bolts to manufacturer specifications.
Tools Required: Gasket scraper, torque wrench.

4. Inspect and Adjust Gear Linkage

Sub-steps:
1. Inspect the gear linkage for any signs of wear or misalignment.
2. Adjust the linkage as necessary to ensure proper engagement.
3. Lubricate any moving parts to ensure smooth operation.
Tools Required: Wrench set, lubricant.

5. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals securely.
