Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid drain plug using a socket set.
2. Drain old fluid into a suitable container.
3. Inspect the old fluid for metal shavings or burnt smell.
4. Replace the drain plug and torque to manufacturer specifications (typically 20-30 ft-lbs).
5. Refill the transmission with new fluid as per manufacturer recommendations (usually Mercon LV or equivalent).

3. Replace Worn Transmission Mount

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission mount and remove the bolts securing it to the frame.
3. Remove the old mount and replace it with a new one.
4. Torque the new mount bolts to the specified value (typically 50-60 ft-lbs).
5. Lower the vehicle and reconnect the battery terminal.

4. Inspect and Replace Universal Joints

Sub-steps:
1. Lift the rear of the vehicle and support it securely on jack stands.
2. Remove the drive shaft by unbolting the U-joint caps.
3. Inspect U-joints for wear or play; replace them if they have excessive movement.
4. Install new U-joint caps, applying grease as necessary, and torque to specifications.
5. Reattach the drive shaft and ensure it is properly aligned.
