Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the ignition coils by unscrewing the retaining bolts and gently pulling them off the spark plugs.
Use a spark plug socket to remove each spark plug.
Inspect each spark plug for signs of wear (deposits, burning, or damage).
Replace with new spark plugs, ensuring they are gapped according to specifications (typically around 0.043 inches).
Reinstall the ignition coils and secure them with the retaining bolts.

3. Check and Replace Transmission Fluid

Tools Required: Torque wrench, transmission fluid pump, drain pan.
Locate the transmission fluid dipstick (if equipped) and check the fluid level.
If the fluid is low or dirty (dark color or burnt smell), remove the transmission pan to drain old fluid.
Replace the transmission filter if applicable.
Reinstall the transmission pan with a new gasket, tightening bolts to manufacturer specifications.
Fill the transmission with new fluid through the dipstick tube, using the proper type (typically T-IV or WS for Toyota).

4. Inspect and Replace Engine Mounts

Tools Required: Socket set, jack and jack stands.
Safely lift the vehicle using a jack and secure with jack stands.
Locate engine mounts (typically at the front and rear of the engine).
Inspect for cracks, wear, or separation.
Remove the bolts securing the mounts and replace them with new mounts.
Torque bolts to the manufacturer’s specifications and lower the vehicle.
