Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery (negative terminal) to prevent electrical issues.

2. Inspect and Replace Transmission Fluid

Tools Required: Transmission funnel, fluid pump, drain pan.
Remove the transmission drain plug and allow old fluid to drain completely.
Inspect the old fluid for metal shavings or burnt smell; replace fluid if necessary.
Reinstall the drain plug and refill with manufacturer-recommended transmission fluid using a funnel.

3. Inspect Driveshaft and Universal Joints

Tools Required: Socket set, torque wrench.
Safely lift and support the vehicle using jack stands.
Remove the driveshaft bolts using a socket set.
Inspect the universal joints for play or damage; replace if necessary.
Reinstall the driveshaft, ensuring bolts are torqued to the manufacturer's specifications.

4. Check Transmission and Engine Mounts

Tools Required: Socket set, pry bar.
Use a socket set to inspect and tighten the transmission and engine mount bolts.
If mounts are worn or cracked, replace them with OEM parts.
Reinstall any components removed during inspection.
