Solution

1. Preparation

Ensure the vehicle is on a level surface and the engine is off.
Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.

2. Change Transmission Fluid

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set.
3. Carefully drop the transmission pan and drain old fluid.
4. Replace the transmission filter if applicable.
5. Clean the transmission pan and magnet; remove any debris.
6. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).

3. Replace Transmission Mounts (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission mounts and inspect for cracks or wear.
3. Remove the bolts securing the mounts using a socket set.
4. Replace with new mounts and torque to manufacturer specifications.
5. Lower the vehicle.

4. Reset Transmission Control Module (TCM)

Sub-steps:
1. Reconnect the battery.
2. Use an OBD-II scanner to reset any transmission-related trouble codes.
3. Drive the vehicle for a short period to allow the TCM to relearn shift patterns.
