Solution

1. Preparation

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

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick (if applicable) or drain plug.
2. Remove the dipstick or drain plug and check fluid level and condition.
3. If the fluid is low or dirty, drain the old fluid completely using a fluid pump or by removing the transmission fluid pan.
4. Replace the filter if applicable, ensuring to clean the pan and remove any debris.
5. Fill with the appropriate type of transmission fluid as specified in the owner’s manual (usually Toyota WS fluid).

3. Replace Worn Motor or Transmission Mounts

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Locate the motor and transmission mounts; inspect for cracks or wear.
3. Remove any components obstructing access to the mounts (such as the air intake duct).
4. Unbolt and remove the damaged mounts using a socket set.
5. Install new mounts, ensuring they are torqued to the specifications listed in the service manual.

4. Inspect and Replace Driveshaft or CV Joints (if necessary)

Sub-steps:
1. Lift the vehicle securely and remove the wheels if necessary for better access.
2. Inspect the driveshaft and CV joints for any signs of damage or excessive play.
3. If damaged, unbolt the driveshaft from the differential and transmission.
4. Replace any faulty CV joints or driveshaft components.
5. Reinstall the driveshaft and ensure all bolts are torqued to specifications.
