Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Raise the vehicle using jack stands and remove the underbody covers if necessary.
Locate the engine mounts and inspect for cracks or excessive wear.
If damaged, remove the old mounts using a socket set.
Install new engine mounts, tightening to the manufacturer's specified torque values (typically around 30-50 ft-lbs).
Reconnect any components that were removed and lower the vehicle.

3. Check and Replace Transmission Fluid

Remove the transmission dipstick and check the fluid level; if low, add the appropriate type of transmission fluid (consult the owner’s manual).
If the fluid appears dark or smells burnt, drain the transmission fluid using a fluid pump.
Replace the filter (if applicable) and refill with new transmission fluid, ensuring it meets manufacturer specifications.

4. Inspect Drivetrain Components

Inspect the driveshaft and CV joints for any visible damage or excessive play.
If any components are worn, replace them using appropriate tools (usually a socket set).
Ensure all bolts are torqued to the specified values.
