4. Replace the transmission filter by removing the transmission pan (remove bolts and gently pry the pan).
5. Install a new filter, ensuring it is seated correctly.
6. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications.

3. Inspect and Replace Torque Converter

Sub-steps:
1. Remove the transmission from the vehicle following the service manual for your model.
2. Disconnect the torque converter from the flex plate (remove the bolts).
3. Replace the torque converter with a new unit, ensuring proper alignment.
4. Reconnect the flex plate and torque bolts to the specified torque value.
5. Reinstall the transmission, ensuring all connections are secure.

4. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it warm up.
3. Check for leaks around the transmission and torque converter.
4. Verify correct fluid levels and top off if necessary.
