Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack stands, torque wrench, multimeter, transmission fluid.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Locate and visually inspect the engine mounts for cracks, tears, or excessive movement.
2. If damaged, remove the bolts securing the engine mount to the engine and the frame using a socket set.
3. Replace with new engine mounts, ensuring they are aligned properly and torque the bolts to manufacturer specifications (usually around 40-50 ft-lbs).

3. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level; add fluid if low.
2. If the fluid is discolored or burnt, drain the transmission fluid by removing the drain plug.
3. Replace with the manufacturer-recommended transmission fluid (typically Toyota ATF WS).
4. Reinstall the drain plug and refill the transmission with the appropriate amount of fluid.

4. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil or spark plug wires carefully.
2. Use a socket wrench to remove the spark plugs, inspecting them for wear or carbon buildup.
3. Replace with OEM spark plugs, ensuring the gap is set correctly as per specifications.
4. Reinstall the ignition coils or spark plug wires securely.
