Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Sub-steps:
- Remove the transmission pan using a socket set.
- Drain the old transmission fluid into a suitable container.
- Replace the transmission filter if applicable.
- Install a new gasket on the transmission pan and bolt it back securely.
- Refill the transmission with the manufacturer-recommended fluid (e.g., Ford Mercon LV).

3. Torque Converter Inspection/Replacement

Sub-steps:
- Remove any components obstructing access to the torque converter (e.g., exhaust parts).
- Disconnect the electrical connector from the torque converter.
- Unbolt the torque converter from the flywheel (typically 4-6 bolts).
- Remove the old torque converter from the transmission.
- Install the new torque converter, ensuring it is fully seated onto the transmission pump.
- Reattach the torque converter to the flywheel and reconnect the electrical connector.

4. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to reach operating temperature.
Check the transmission fluid level again and add fluid as necessary.
Conduct a test drive to verify the repair and observe for any symptoms.
