Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or drain plug.
2. If needed, drain the old transmission fluid into a suitable container.
3. Replace the filter (if applicable) by removing the transmission pan.
4. Refill with new transmission fluid, ensuring to use the manufacturer-recommended type (typically Toyota Type T-IV).
5. Check fluid level again and ensure it is within the recommended range.

3. Replace Transmission Mounts

Sub-steps:
1. Identify and remove the bolts securing the transmission mount to the transmission and chassis.
2. Replace any worn or damaged mounts with new mounts.
3. Torque bolts to the manufacturer’s specifications (usually around 40-50 ft-lbs).
4. Recheck all mounting points for security.

4. Inspect Driveshaft and CV Joints

Sub-steps:
1. Remove any protective covers to access the driveshaft and CV joints.
2. Check the driveshaft for any signs of bending or wear.
3. Inspect CV joints for torn boots or play; replace if damaged.
4. Reassemble and ensure all components are torqued to the specified value.
