Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and safely lift it using jack stands if necessary.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
- Locate the engine and transmission mounts.
- Use a socket set to remove the bolts securing the mounts.
- Inspect the mounts for cracks or excessive wear.
- Replace any faulty mounts with new OEM parts.
- Torque the new mount bolts to the manufacturer's specifications (consult service manual for exact values).

3. Check and Replace Transmission Fluid

Sub-steps:
- Locate the transmission fluid dipstick or fill plug.
- Remove the dipstick and check the fluid level and color.
- If the fluid is low or discolored, drain the old fluid using a fluid pump and replace with the recommended transmission fluid.
- Refill the transmission with the correct amount of fluid as per manufacturer specifications.

4. Inspect and Replace Drive Belts

Sub-steps:
- Locate the drive belts and visually inspect for cracks or fraying.
- Use a wrench to relieve tension on the belt tensioner.
- Remove the old belt and install a new one, ensuring it is properly aligned on the pulleys.
- Reapply tension according to manufacturer specifications.
