1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secured with jack stands if elevated.
Disconnect the battery to ensure safety during repairs.

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel
Remove the transmission dipstick and check the fluid level and condition.

Replace the drain plug and torque it to the manufacturer’s specifications.
Refill with the correct amount of new transmission fluid through the dipstick tube.

4. Inspect and Replace Motor and Transmission Mounts

Tools Required: Socket set, pry bar
Remove any components obstructing access to the motor and transmission mounts.
Inspect the mounts for cracks or excessive wear.
If damaged, remove the old mounts and install new ones, ensuring they are properly torqued.

5. Inspect Driveshaft and CV Joints

Tools Required: Socket set, pry bar
Remove the driveshaft if necessary for access.
Check for play in the CV joints and inspect for torn boots.
Replace any damaged components as needed.
