Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid, funnel, jack and jack stands, socket set.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission fluid dipstick or fill plug.
3. Remove the dipstick or fill plug and check the fluid level.
4. If low, add the recommended transmission fluid until the proper level is reached.
5. If the fluid is dark or has a burnt smell, drain the old fluid using a drain plug (if equipped).
6. Replace with new transmission fluid per manufacturer specifications.
7. Reinstall the dipstick or fill plug securely.

3. Inspect and Replace Transmission Control Module (if necessary)

Sub-steps:
1. Access the transmission control module (consult repair manual for location).
2. Disconnect the electrical connectors from the TCM.
3. Remove the TCM using a socket set.
4. Replace with a new TCM if diagnostic steps indicated a malfunction.
5. Reconnect all electrical connectors and secure the module.

4. Check and Replace Engine Mounts (if necessary)

Sub-steps:
1. Inspect engine mounts for cracks or excessive wear.
2. Remove any components obstructing access to the engine mounts.
3. Unbolt the damaged mounts using a socket set.
4. Replace with new engine mounts.
5. Torque the new mounts to the manufacturer's specifications and reassemble any removed components.
