Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid, and a jack.
Ensure the vehicle is on a level surface and the engine is off before starting work.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts and visually inspect them for cracks or excessive wear.
3. If damaged, remove the bolts securing the engine mounts to the engine and chassis (use torque wrench for reinstallation).
4. Replace with new engine mounts and torque to manufacturer specifications.

3. Check and Replace Ignition Components

Sub-steps:
1. Remove the engine cover (if applicable) to access ignition coils and spark plugs.
2. Use a spark plug socket to remove the spark plugs and inspect their condition.
3. Replace spark plugs if worn or fouled (use OEM recommended type).
4. Test ignition coils with a multimeter to check for proper resistance; replace any faulty coils.

4. Transmission Fluid Service

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick and check the fluid level; top off if necessary.
3. If fluid is dark or burnt, drain the old fluid using a drain pan.
4. Replace with new transmission fluid (use manufacturer-recommended type) and check levels after refilling.
