Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan, socket set.
Sub-steps:
1. Remove the transmission fluid pan using a socket set.
2. Allow old fluid to drain completely into the drain pan.
3. Inspect the fluid for metal shavings or burnt smell, which indicates internal damage.
4. Replace the transmission filter if applicable.
5. Reinstall the pan with a new gasket, torquing bolts to the manufacturer's specifications (typically 8-10 ft-lbs).
6. Refill the transmission with the correct type and amount of fluid (Toyota ATF WS).

3. Inspect and Replace Transmission Mounts

Tools Required: Jack and jack stands, socket set, torque wrench.
Sub-steps:
1. Support the transmission with a jack.
2. Remove the bolts securing the transmission mounts using a socket set.
3. Inspect the mounts for cracks or signs of wear.
4. Install new mounts, ensuring they are properly aligned and secured with bolts torqued to the specified value (usually around 40-50 ft-lbs).

4. Examine and Repair Driveshaft or CV Joints

Tools Required: Jack and jack stands, socket set, pry bar.
Sub-steps:
1. Raise the vehicle and secure it with jack stands.
2. Inspect the driveshaft for any play or damage by wiggling it with a pry bar.
3. If any issues are found, remove the driveshaft by disconnecting the bolts at the transmission and differential.
4. Replace worn CV joints or driveshaft components as needed.
5. Reinstall the driveshaft ensuring all bolts are torqued to spec (typically around 15-20 ft-lbs).
