Solution

1. Preparation

Tools Required: Floor jack, jack stands, OBD-II scanner, transmission fluid, differential fluid, socket set.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety when working on electrical components.

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level and condition.
If fluid is low, add the correct type of transmission fluid as specified in the owner’s manual.
If the fluid is dark or has a burnt smell, perform a fluid change:
- Drain the old fluid by removing the transmission pan.
- Replace the filter and gasket, then reassemble.
- Fill with new transmission fluid as per manufacturer specifications.

3. Inspect and Replace Differential Fluid

Locate the differential fill plug and remove it.
Check the fluid level; if low, drain the old fluid.
Replace with the appropriate differential fluid type and fill to the proper level.
Replace the fill plug and ensure it is tight.

4. Repair or Replace Worn Components

If transmission mounts are damaged, replace them:
- Remove any securing bolts and lift the transmission slightly to remove old mounts.
- Install new mounts and torque bolts to manufacturer specifications.
For any worn driveshaft or U-joint, replace them:
- Remove the driveshaft by unbolting it from the rear differential and transmission.
- Replace U-joints if they show excessive play, and reinstall the driveshaft.
