Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before starting any repairs.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if applicable) or the fill port.
Remove the dipstick or fill plug and check fluid level using a clean rag.
If the fluid is low, use a fluid pump to add the manufacturer-recommended transmission fluid. If the fluid is dark or smells burnt, a fluid change may be necessary.
Start the engine and let it idle, then shift through each gear while checking the fluid level again.

3. Inspect and Replace Transmission Mount

Raise the vehicle using a jack and secure it with jack stands.
Locate the transmission mount and visually inspect it for cracks or deformation.
If damage is found, use a socket set to unbolt the transmission mount from the transmission and the frame.
Replace the mount with a new one and torque the bolts to the manufacturer specifications.

4. Check Driveshaft and Universal Joints

Inspect the driveshaft for any visible damage or excessive play.
Check the universal joints by attempting to move them manually; they should not have any play.
If the universal joints are worn, remove the driveshaft using a socket set and replace the joints or the entire driveshaft as needed.

5. Inspect Engine Mounts

Visually inspect the engine mounts for signs of wear or looseness.
If any mounts are damaged, replace them following the same procedure used for the transmission mount.
