3. Allow the fluid to completely drain into a suitable container.
4. Replace the transmission filter if equipped.
5. Reinstall the transmission pan with a new gasket, tightening to the manufacturer's torque specifications (usually 8-12 ft-lbs).
6. Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Replace Components if Necessary

Sub-steps:
1. If leaks are present, replace the affected seals or gaskets.
2. Inspect the transmission cooler and lines for any blockages or leaks and clear or replace as necessary.
3. Check the condition of the torque converter and replace if damaged.

4. Reconnect Battery and Test Drive

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Take the vehicle for a test drive to ensure proper shifting and monitor for any new smells or issues.
