Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid, and basic hand tools.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Spark Plugs (if faulty)

Remove the engine cover (if applicable) to access the spark plugs.
Disconnect the ignition coil connectors and remove the coils.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plugs for wear; replace them with OEM or equivalent spark plugs if necessary.
Reinstall the coils and connectors, ensuring proper seating.

3. Check and Replace Engine Mounts (if damaged)

Lift the vehicle using a jack and secure with jack stands.
Inspect the engine mounts for cracks or excessive wear.
If damaged, remove the bolts securing the engine mount to the frame and engine.
Replace the mount with a new OEM part, tightening the bolts to the manufacturer’s specified torque settings.

4. Transmission Fluid Change (if needed)

Place a drain pan under the transmission pan.
Remove the transmission pan bolts and lower the pan to drain the old fluid.
Replace the filter if applicable and clean the pan.
Reinstall the pan with a new gasket, tightening bolts to specified torque.
Fill the transmission with the correct type and amount of fluid as per the manufacturer’s specifications.
