Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove any components obstructing access to the engine mounts.
Use a pry bar to lift the engine slightly if necessary.
Remove the bolts securing the engine mount to the frame and engine.
Replace the old mounts with new ones, ensuring they are aligned properly.
Torque the bolts to the manufacturer’s specifications.

3. Transmission Fluid Change

Tools Required: Torque wrench, drain pan, funnel
Locate the transmission fluid pan; remove the drain plug to drain old fluid into a pan.
Replace the filter if applicable, following manufacturer guidelines.
Reinstall the drain plug and refill the transmission with new fluid using the correct type and quantity as specified in the owner’s manual.

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

Tools Required: Socket set, torque wrench
Remove the engine cover (if equipped) to access the ignition coils and spark plugs.
Disconnect the electrical connectors from the ignition coils.
Remove the coils and spark plugs, inspecting them for wear or damage.
Install new spark plugs to the manufacturer’s torque specifications and replace the ignition coils.
