Sub-steps:
- Locate the torque converter lock-up solenoid within the transmission.
- Remove any necessary components for access (e.g., transmission pan).
- Disconnect the electrical connector and unbolt the solenoid.
- Replace with a new solenoid and reassemble components.

4. Replace Torque Converter (if necessary)

Sub-steps:
- Raise the vehicle securely on jack stands.
- Disconnect the driveshaft and any electrical connections to the transmission.
- Unbolt the torque converter from the flywheel and remove it from the transmission.
- Install the new torque converter, ensuring it is seated properly.
- Reattach the driveshaft and electrical connections, then lower the vehicle.
