Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert and remove the dipstick again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid.
If fluid is dark or smells burnt, a transmission flush may be required.

Locate the transmission and engine mounts.
Use a socket set to remove bolts securing the mounts to the vehicle frame.
Inspect for cracks or excessive wear; replace if necessary.
Reinstall new mounts and torque to the manufacturer specifications.

4. Examine Drive Shafts and CV Joints

Lift the vehicle using a jack and secure with jack stands.
Inspect the drive shafts for any signs of damage such as dents or cracks.
Check CV joints for torn boots or excessive play; replace if damaged.
Reassemble any components removed during inspection.

5. Adjust Transmission Linkage

Locate the transmission linkage and check for any misalignment.
Adjust the linkage according to the service manual specifications.
Ensure that the linkage is securely fastened and operates smoothly.
