5. Reinstall the transmission pan and torque the bolts to the manufacturer's specifications (typically 10-12 ft-lbs).
6. Fill the transmission with the recommended fluid through the dipstick tube or fill port.

3. Inspect and Adjust Shift Linkage

Sub-steps:
1. Locate the shift linkage assembly on the transmission.
2. Inspect for any wear, damage, or misalignment.
3. Adjust the linkage as needed to ensure proper engagement of gears.
4. Test the linkage operation by moving through all gears with the engine running.
