Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect Transmission Fluid

Remove the transmission dipstick (if applicable).
Wipe it clean, reinsert, and remove again to check the level.
If low, add the recommended transmission fluid type as per the owner's manual.

3. Check for Leaks

Visually inspect the transmission pan, seals, and surrounding areas for any signs of fluid leaks.
If leaks are found, identify the source and replace the faulty seals or gaskets.

4. Examine Driveshaft and CV Joints

Safely lift the vehicle using jack stands.
Inspect the driveshaft for any signs of damage or excessive play.
Check CV joints for torn boots or grease leaks; replace if necessary.

5. Adjust Transmission Linkage

Locate the transmission linkage and check for proper alignment.
If misaligned, adjust the linkage according to the manufacturer’s specifications.

6. Replace Engine/Transmission Mounts (if necessary)

If mounts are found to be worn, remove the old mounts using a socket set.
Install new mounts, ensuring they are tightened to the manufacturer's torque specifications.
