Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle using jack stands if working underneath.

2. Inspect and Replace Transmission Fluid (if necessary)

Tools Required: Socket set, drain pan, funnel, new transmission fluid.
Remove the transmission fluid pan bolts and carefully lower the pan to drain the old fluid.
Replace the transmission filter if applicable, and clean the pan.
Reinstall the pan, torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).
Refill with the appropriate type of transmission fluid as specified in the owner’s manual.

3. Replace Worn Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar.
Remove the bolts securing the engine and transmission mounts using the socket set.
Carefully lift the engine/transmission slightly with a jack to relieve pressure on the mounts.
Remove the old mounts and install the new ones, ensuring proper alignment.
Torque the bolts to specification (refer to service manual for exact values).

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench.
Remove the ignition coils or spark plug wires to access the spark plugs.
Use the spark plug socket to remove the old spark plugs.
Inspect the old plugs for wear and replace with new plugs, torquing to the specified value (usually around 13-15 ft-lbs).
