Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Engine Mounts

Locate Engine Mounts: Identify the engine mounts, typically found between the engine and the vehicle's frame.
Remove Fasteners: Use a socket set to remove the bolts securing the engine mounts to the frame and engine.
Check Condition: Inspect the mounts for cracks, tears, or excessive wear.
Install New Mounts: If damaged, replace them with new mounts. Tighten the bolts to the manufacturer’s torque specifications (usually around 40-50 ft-lbs).
Reinstall Fasteners: Securely fasten all components and reconnect the negative battery terminal.

3. Transmission Fluid Service

Check Fluid Level: With the engine running, check the transmission fluid level using the dipstick.
Drain Fluid: If low or dirty, drain the old fluid using a fluid pump or by removing the transmission pan.
Replace Filter: If applicable, replace the transmission filter according to service manual specifications.
Add New Fluid: Refill with manufacturer-recommended transmission fluid (typically Toyota Type T-IV).
Check for Leaks: Start the engine and check for leaks around the pan and filter.

4. Ignition System Inspection

Remove Spark Plugs: Use a spark plug socket to remove spark plugs for inspection.
Inspect Condition: Check for wear and fouling; replace if necessary.
Check Ignition Coils: Test ignition coils with a multimeter to ensure proper resistance values.
Replace Components: If any components are faulty, replace them with OEM parts.
