3. Remove the bolts securing the mounts using a socket set and replace them with new mounts if damaged.
4. Torque the new mounts to the manufacturer's specifications.
5. Lower the vehicle and reconnect the battery.

4. Reprogram Transmission Control Module (if necessary)

Tools Required: OBD-II scanner with programming capability.
Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Follow the scanner's prompts to reprogram or update the TCM software.
3. Clear any error codes and perform a test drive to ensure proper function.
