Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues during the service.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid drain plug and allow fluid to drain into a suitable container.
2. Replace the drain plug and tighten it to the manufacturer’s specified torque (typically around 30 ft-lbs, but check the specific value).
3. Remove the transmission fluid fill plug and use a funnel to refill new transmission fluid (ensure you use the correct type, typically Toyota Type T-IV or WS).
4. Start the engine and cycle through the gears with the brake applied to circulate the new fluid.
5. Check for any leaks around the drain and fill plugs after refilling.

3. Inspect and Replace Mounts

Sub-steps:
1. Visually inspect engine and transmission mounts for cracks or signs of wear.
2. If damaged, remove the bolts securing the mounts using a socket set.
3. Replace with new mounts, ensuring correct alignment.
4. Torque the mounting bolts to the manufacturer's specifications.

4. Check Drivetrain Components

Sub-steps:
1. Inspect CV joints and drive shafts for any signs of damage or excessive play.
2. If any components appear worn, remove them carefully using a socket set.
3. Replace with new components, ensuring proper alignment and connection.
4. Reinstall any protective covers or shields.
