Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, multimeter, transmission fluid, replacement spark plugs, and any necessary fluids.
Disconnect the negative battery terminal to ensure safety.

2. Address Spark Plugs

Remove engine cover (if applicable) to access the spark plugs.
Use a socket set to carefully remove each spark plug.
Inspect each plug for wear, carbon buildup, or damage; replace with OEM plugs if necessary.
Torque new spark plugs to manufacturer specifications (usually around 15-20 ft-lbs).
Reattach the engine cover.

3. Inspect and Service Transmission

Locate the transmission dipstick and check fluid level.
If low, add the recommended transmission fluid type (consult the owner’s manual).
If the fluid is dark or has a burnt smell, perform a transmission fluid change.
To change fluid, drain it using the transmission pan drain plug, replace the filter, and refill with new fluid to the specified level.

4. Examine Drive Shafts and CV Joints

Safely lift the vehicle using a jack and support it with jack stands.
Visually inspect the drive shafts and CV joints for any visible wear, cracks, or tears in the rubber boots.
Replace any damaged components as necessary.

5. Check Engine Mounts

Inspect engine mounts by visually checking for cracks or separations.
If damaged, replace engine mounts with OEM parts to reduce vibrations.
