Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Mounts

Locate the engine mounts: Identify the engine mount points under the hood and near the transmission.
Remove the engine mount bolts: Use a socket set to carefully unbolt the engine mounts from the engine and chassis.
Replace worn mounts: Install new engine mounts, ensuring they are oriented correctly.
Torque the bolts: Follow the manufacturer’s specifications for torque settings when reattaching the bolts.

3. Check and Replace Spark Plugs

Remove spark plug wires: Carefully detach the spark plug wires or coils from the spark plugs.
Extract old spark plugs: Use a spark plug socket to remove the old spark plugs from the cylinder head.
Install new spark plugs: Insert new spark plugs and hand-tighten them before using a torque wrench to tighten to the specified torque.
Reattach wires: Securely reconnect the spark plug wires or coils.

4. Inspect and Top Off Transmission Fluid

Locate the transmission dipstick: Find the dipstick or fill port for the transmission.
Check fluid level: Pull the dipstick, wipe it clean, then reinsert and check the level.
Add fluid if necessary: If the fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.
Inspect for leaks: Check for any visible leaks around the transmission seals and pan.
