Solution

1. Preparation

Gather tools and materials needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Inspection

Tools Required: Fluid pump, drain pan.
Remove the transmission fluid dipstick and check the fluid level.
If the fluid is low, add the correct type of ATF for your vehicle (refer to owner's manual).
If the fluid is dark or has a burnt smell, consider a transmission fluid change.

3. Engine Mount Replacement

Tools Required: Socket set, torque wrench, pry bar.
Lift the vehicle using a jack and secure it with jack stands.
Locate the engine mounts and inspect for cracks or excessive wear.
Remove the bolts securing the damaged engine mount using a socket set.
Replace the old mount with a new one, tightening to the manufacturer’s specified torque values.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar, safety glasses.
Raise the vehicle and secure it on jack stands.
Inspect the driveshaft for any visible damage or play.
Check CV joints for torn boots or grease leakage; replace if necessary.

5. Ignition System Repair

Tools Required: Socket set, multimeter.
Remove the ignition coils and inspect the spark plugs for wear; replace if they are worn or fouled.
Test the ignition coils with a multimeter for proper resistance; replace any faulty coils.
