Solution

1. Preparation

Gather tools needed: socket set, torque wrench, OBD-II scanner, transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Transmission Fluid

Check Fluid Level:
- Remove the transmission dipstick.
- Wipe it clean, reinsert, and remove to check fluid level.
Change Fluid (if needed):
- Drain the old transmission fluid using a pan to catch it.
- Replace with manufacturer-recommended transmission fluid (e.g., Toyota ATF WS).
- Refill with new fluid to the proper level.

3. Inspect and Replace Transmission and Engine Mounts

Remove Old Mounts:
- Use a socket set to remove the bolts securing the mounts.
- Lift the engine/transmission slightly using a jack for clearance.
Install New Mounts:
- Position the new mounts and secure them with the bolts.
- Torque bolts to manufacturer specifications (refer to service manual).

4. Inspect and Replace Universal Joints/Driveshaft

Check Universal Joints:
- Examine for excessive play or rust.
- If damaged, remove the driveshaft by unbolting it from the differential and transmission.
Install New Universal Joints:
- Replace with new joints and reassemble the driveshaft, ensuring proper alignment.
- Torque bolts to manufacturer specifications.
