Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Transmission Fluid Change

Tools Required: Fluid pump, 10mm socket, drain pan, funnel.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the transmission drain plug using a 10mm socket and allow the old fluid to drain completely into the drain pan.
3. Inspect the drain plug for metal shavings or debris; clean or replace as necessary.
4. Replace the drain plug with a new washer, torque to the manufacturer’s specifications.
5. Using a fluid pump, refill the transmission with the recommended fluid type (e.g., Toyota ATF WS) through the fill hole.
6. Start the engine, cycle through the gears, and check the fluid level again, topping off as necessary.

3. Inspect and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Identify the engine and transmission mounts by consulting the service manual.
2. Remove the bolts securing the mounts using the socket set.
3. Inspect mounts for cracks, separation, or excessive wear.
4. Replace any faulty mounts with new components, tightening bolts to the specified torque values.

4. CV Joint and Drive Shaft Inspection

Tools Required: Socket set, pry bar.
Sub-steps:
1. Inspect the CV joints and drive shafts visually for any signs of grease leakage or damaged boots.
2. If any damage is found, remove the affected CV joint or drive shaft using the socket set.
3. Replace with new parts and ensure proper installation according to specifications.
