Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety.
Raise the vehicle using a jack and secure it on jack stands.

2. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and remove again to check fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
Check fluid condition; if burnt or contaminated, a fluid change is needed.

3. Inspect and Replace Transmission Mount

Locate the transmission mount under the vehicle.
Remove the bolts securing the mount using a socket set.
Lift the transmission slightly using a jack to relieve pressure on the mount.
Replace the old mount with a new one, ensuring it is properly aligned.
Torque the mounting bolts to the manufacturer’s specifications.

4. Inspect Drive Shaft and Universal Joints

Check the drive shaft for any visible damage or play.
Inspect the universal joints for lubrication and wear.
If damaged, remove the drive shaft and replace the universal joints or entire drive shaft as necessary.

5. Reassemble and Reconnect

Once all inspections and repairs are completed, reassemble any components removed.
Reconnect the battery.
Lower the vehicle from the jack stands.
