Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is cool.
Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, multimeter, transmission fluid.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Locate the transmission dipstick (if applicable) or the fill plug.
3. Remove the dipstick or fill plug and check the fluid level and condition. If the fluid is dark or has a burnt smell, it needs to be replaced.
4. If necessary, drain the old transmission fluid using a drain pan, then replace it with the manufacturer-recommended fluid.
5. Reinstall the dipstick or fill plug and ensure it is secured properly.

3. Inspect and Replace Worn Engine Mounts

Sub-steps:
1. Visually inspect the engine mounts for cracks or excessive wear.
2. If any mounts are damaged, use a socket set to remove the bolts securing the mounts to the engine and frame.
3. Replace with new engine mounts, ensuring they are properly aligned, and torque to the manufacturer’s specifications.
4. Reinstall any components that were removed for access.

4. Examine and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if required to access the spark plugs.
2. Using a socket, remove the spark plugs and inspect them for wear or fouling.
3. If they are worn, replace them with new, manufacturer-specified spark plugs.
4. Torque new spark plugs to the manufacturer’s recommended specifications.
