Solution

1. Preparation

Gather tools needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Replace Worn Engine Mounts

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts; typically, there are two or three mounts.
3. Remove any components obstructing access to the mounts (e.g., air intake).
4. Use a pry bar to relieve tension on the mount and remove the mounting bolts.
5. Replace the old mount with a new one and torque the bolts to the manufacturer's specifications.

3. Change Transmission Fluid

Tools Required: Transmission fluid pump, fluid catch pan, socket set, funnel.
Sub-steps:
1. Locate the transmission drain plug and remove it to drain the old fluid into the pan.
2. Replace the drain plug after all fluid has drained.
3. Access the transmission fill port and use the pump to add new transmission fluid until it reaches the proper level (consult the owner’s manual for fluid type and capacity).
4. Start the engine and cycle through the gears to circulate the new fluid, then check fluid levels again and add if necessary.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Sub-steps:
1. Remove the engine cover if applicable to access the spark plugs.
2. Disconnect the ignition coils from the spark plugs.
3. Use a socket to remove the spark plugs from the cylinder head.
4. Inspect the old plugs for wear; replace them with new plugs if needed (ensure proper gap).
5. Reinstall the ignition coils and engine cover.
