Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid drain plug and allow fluid to drain into a clean container.
2. Inspect the old fluid for metal shavings or burnt smell.
3. Replace with new transmission fluid as per the manufacturer’s specifications (typically Toyota Type T-IV).
4. Reinstall the drain plug and torque to the manufacturer’s specification (usually around 30 ft-lbs).

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, torque wrench, jack stands, pry bar
Sub-steps:
1. Safely lift the vehicle using jack stands.
2. Locate the transmission mounts; typically found on the side or rear of the transmission.
3. Inspect for cracks or excessive wear.
4. Remove the bolts securing the mounts and carefully replace them with new ones.
5. Torque bolts to the specified value (usually around 40-50 ft-lbs).

4. Inspect and Repair Driveshaft/CV Joints

Tools Required: Socket set, pry bar
Sub-steps:
1. Visually inspect the driveshaft and CV joints for visible wear or damage.
2. If damage is found, remove the driveshaft by unbolting it from the differential and the transmission.
3. Replace worn CV joints or the entire driveshaft as necessary.
4. Reinstall and torque the bolts to manufacturer specifications.
