Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Transmission Fluid Change

Drain Old Fluid:
- Locate the transmission drain plug and use a socket wrench to remove it.
- Allow the fluid to completely drain into a suitable container.
Replace Filter (if applicable):
- Remove the transmission pan by unscrewing the bolts.
- Replace the transmission filter and gasket.
Refill New Fluid:
- Reinstall the transmission pan and torque bolts to manufacturer specifications.
- Refill the transmission with the recommended fluid using a funnel.

3. Inspect and Replace Engine Mounts (if needed)

Remove Components:
- Access engine mounts by removing any obstructing components (like air intake or battery).
Inspect Mounts:
- Check for cracks or excessive wear on the rubber part of the mounts.
Replace Mounts:
- If damaged, remove the old mounts using a socket set.
- Install new mounts and torque bolts to specifications.

4. Spark Plug and Ignition Coil Replacement (if needed)

Remove Old Spark Plugs:
- Disconnect ignition coil connectors.
- Remove the ignition coils using a socket wrench.
- Use a spark plug socket to remove old spark plugs.
Install New Spark Plugs:
- Apply anti-seize compound on the threads of new spark plugs.
- Install new spark plugs and tighten to the manufacturer’s torque specification.
Reinstall Ignition Coils:
- Reattach ignition coils and connectors.
