Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working with electrical components.
Allow the vehicle to cool down if it has been running.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick or filler plug.
Remove the dipstick or plug. Use a fluid pump to extract old transmission fluid if necessary.
Inspect the fluid for contamination (metal shavings, burnt smell) and replace it with manufacturer-recommended fluid if needed.
Refill with new transmission fluid to the proper level as specified in the owner’s manual.

3. Inspect and Replace Motor and Transmission Mounts

Support the transmission and engine using a jack and appropriate blocks.
Remove the bolts securing the motor and transmission mounts using a socket set.
Inspect mounts for cracks, tears, or excessive wear. Replace if damaged.
Install new mounts, ensuring they are aligned properly, and torque bolts to manufacturer specifications.

4. Inspect and Replace Driveshaft and CV Joints

Raise the vehicle securely on jack stands.
Inspect the driveshaft for any play or damage, and check CV joints for torn boots or grease leakage.
If any issues are found, remove the driveshaft by loosening the bolts at both ends.
Replace any damaged CV joints or the entire driveshaft if necessary; reassemble in reverse order, ensuring proper torque specifications are followed.
