Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, transmission jack, torque wrench, inspection lights.
Ensure the vehicle is on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical issues during repairs.

2. Check and Replace Transmission Fluid

Drain the transmission fluid: Remove the drain plug or transmission pan, allowing the fluid to fully drain into a container.
Replace the transmission filter: Remove the old filter, install a new one, and ensure it is properly seated.
Refill transmission fluid: Use the manufacturer-recommended fluid type and quantity. Check the owner's manual for specifications.

3. Inspect and Replace Engine/Transmission Mounts

Remove any components obstructing access: This may include air intake assemblies, battery, or other parts.
Unbolt the damaged mounts: Use a socket set to remove the bolts securing the mounts to the engine and chassis.
Install new mounts: Position the new mounts and tighten bolts to the manufacturer's torque specifications.

4. Inspect and Repair Drive Shaft

Remove the drive shaft: Unbolt the universal joints from the differential and transmission, and carefully slide the drive shaft out.
Inspect for wear or damage: Look for any signs of play or wear in the U-joints and the shaft itself.
Replace if necessary: Install a new drive shaft or U-joints and ensure proper alignment when re-installing.
