3. Replace the drain plug and torque it to the manufacturer's specification (consult the service manual for the exact torque).
4. Remove the transmission fluid fill plug located on the transmission.
5. Use a funnel to add the new transmission fluid (check the owner’s manual for the correct fluid type and capacity).

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing all bolts securing it.
2. Carefully detach the pan and drain any remaining fluid.
3. Remove the old transmission filter and replace it with a new one.
4. Clean the gasket surface on the transmission and the pan.
5. Install a new gasket and reattach the transmission pan, ensuring it is torqued to specifications.

4. Reconnect Battery

Reconnect the battery terminals and ensure they are tight.

5. Test Drive

Start the vehicle and allow it to warm up.
Test drive the vehicle under various conditions to ensure the transmission is operating smoothly without slipping.
