Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Transmission Fluid Inspection

Remove the transmission dipstick and check the fluid level.
If low, add the correct type of fluid (consult the owner’s manual for specifications).
If the fluid appears dark or burnt, consider a fluid change.

3. Engine Mount Replacement

Tools Required: Socket set, torque wrench.
Locate the engine mounts and inspect for cracks or excessive wear.
Use the socket set to remove the bolts securing the damaged mount.
Install the new mount and torque the bolts to the manufacturer's specifications.

4. Driveshaft and CV Joint Inspection

Lift the vehicle using a jack and secure it with jack stands.
Inspect the driveshaft for any visible damage or play in the CV joints.
Replace any damaged components as needed, ensuring to torque to specification.

5. Ignition System Check

Remove spark plug leads and check spark plugs for wear; replace if necessary.
Check ignition coils with a multimeter to ensure they are within specifications.
Reinstall components securely.
