Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely elevate it using jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine/Transmission Mounts

Remove Underbody Shield (if applicable):
- Use a socket set to remove screws/bolts securing the underbody shield.
Inspect Engine and Transmission Mounts:
- Visually check for signs of cracks or deterioration.
Replace Damaged Mounts:
- Remove the bolts securing the faulty mount using a wrench.
- Install the new mount and torque to manufacturer specifications (typically around 50-60 Nm, but verify with service manual).
- Repeat for any additional mounts needing replacement.

3. Spark Plug and Ignition Coil Replacement

Access the Spark Plugs:
- Remove any engine covers or components obstructing access.
Remove Old Spark Plugs:
- Use a spark plug socket and ratchet to remove the spark plugs.
Install New Spark Plugs:
- Apply anti-seize lubricant on new plugs (if recommended).
- Torque to specifications (usually around 25-30 Nm).
Replace Ignition Coils (if necessary):
- Disconnect the electrical connector, remove bolts, and replace with new coils.

4. Transmission Fluid Change

Drain Old Fluid:
- Locate the transmission pan and remove the drain plug or pan bolts.
Replace Filter (if applicable):
- Remove the old filter and install the new one.
Reinstall the Pan:
- Clean the mating surfaces, apply new gasket material if necessary, and torque the bolts to specifications.
Refill with New Transmission Fluid:
- Use the manufacturer-recommended transmission fluid and fill to the appropriate level.
