Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, multimeter, vacuum gauge.
Safety Warnings: Ensure the vehicle is on a flat surface and securely raised if jacked up.

2. Engine Mount Inspection and Replacement

Sub-steps:
1. Open the hood and visually inspect the engine mounts for cracks or excessive wear.
2. If damaged, use the socket set to remove the bolts securing the engine mount to the engine and the vehicle frame.
3. Replace with new engine mounts, ensuring they are torqued to the manufacturer's specifications.

3. Transmission Fluid Change

Sub-steps:
1. Locate the transmission pan and remove the bolts using the socket set.
2. Drain the old transmission fluid into a catch pan.
3. Replace the transmission filter if equipped, following the manufacturer's specifications.
4. Reinstall the transmission pan and torque the bolts to the specified value.
5. Fill the transmission with new fluid through the dipstick tube, checking the level with the multimeter.

4. Spark Plug and Ignition Coil Replacement

Sub-steps:
1. Remove the ignition coil covers using the socket set.
2. Disconnect the electrical connectors and remove the coils.
3. Remove the old spark plugs using a spark plug socket.
4. Install new spark plugs and ignition coils, ensuring they are properly seated and torqued to specifications.
