Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather tools: OBD-II scanner, socket set, torque wrench, jack and jack stands, multimeter.

2. Engine Mount Inspection

Locate the engine mounts; they are typically found on the front and rear of the engine.
Visually inspect the mounts for any visible cracks or signs of wear.
Use a pry bar to lift the engine slightly and observe if there is excessive movement in the mounts.
If damaged, remove the bolts securing the engine mount and replace it with a new one, ensuring it is properly torqued to manufacturer specifications.

3. Spark Plug and Ignition Coil Replacement

Remove the engine cover if necessary to access the spark plugs.
Disconnect the ignition coils by unplugging the electrical connectors.
Remove the bolts securing the ignition coils and take them out.
Use a spark plug socket to remove the old spark plugs; check the gap and condition of each.
Install new spark plugs with the correct gap and torque them to the manufacturer’s specifications.
Reinstall the ignition coils and ensure they are properly connected.

4. Transmission Fluid Check and Change

Locate the transmission dipstick or drain plug.
Check the fluid level and condition; if it’s low or burnt, proceed to change it.
If necessary, drain the old fluid using a drain pan.
Refill with the correct type of transmission fluid as specified in the owner’s manual.
Start the engine and cycle through the gears to ensure the fluid circulates properly.

5. Driveshaft and CV Joint Inspection

Raise the vehicle using a jack and secure it with jack stands.
Inspect the driveshaft for any noticeable damage or play; shake it gently to check for excessive movement.
Examine the CV joints for torn boots or leaking grease.
If any components are damaged, replace the driveshaft or CV joints as needed.
