Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather all necessary tools and replacement parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts and inspect for cracks or excessive wear.
3. If damaged, remove the bolts securing the mount to the engine and subframe.
4. Install new engine mounts and torque bolts to the manufacturer’s specifications (typically around 30-50 Nm).

3. Replace Spark Plugs and Ignition Coils (if necessary)

Sub-steps:
1. Remove the engine cover (if applicable) to access the spark plugs.
2. Disconnect the ignition coils by removing the electrical connectors.
3. Unscrew and remove the old spark plugs using a spark plug socket.
4. Install new spark plugs (gap to manufacturer specifications, usually 0.7-0.8 mm).
5. Reinstall ignition coils and reconnect the electrical connectors.

4. Check and Replace Transmission Fluid (if necessary)

Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. Check the fluid level and condition (should be red and clear).
3. If low or dirty, drain the transmission fluid using a drain pan.
4. Replace with new transmission fluid (consult the owner's manual for the correct type).
5. Reinsert the dipstick and check the level again.
