Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Use a funnel to add new Toyota-compatible transmission fluid if levels are low.
3. If the fluid is dirty or burnt, drain the transmission fluid by removing the drain plug.
4. Replace the fluid with new fluid according to the manufacturer's specifications (check the owner's manual for the correct type and amount).

3. Check and Replace Engine/Transmission Mounts

Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or deterioration.
2. If damaged, remove the bolts securing the mounts using a socket set.
3. Lift the engine/transmission slightly to relieve pressure on the mounts.
4. Remove the old mounts and install new ones, ensuring they are properly aligned and torqued to manufacturer specifications.

4. Inspect Driveshaft and CV Joints

Sub-steps:
1. Raise the vehicle securely and remove the wheels if necessary for better access.
2. Examine the driveshaft for any looseness or wear, and check the CV joints for grease leakage or damage.
3. If any components are damaged, replace them, ensuring to torque the new parts according to specifications.
