1. Preparation

Gather tools: mechanic's stethoscope, OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Drive Belt

Sub-steps:
1. Remove any engine covers if necessary using a socket set.
2. Visually inspect the drive belt for cracks, fraying, or glazing.
3. If damaged, release tension on the idler pulley and remove the belt.

2. Replace any damaged pulleys or tensioners as needed.
3. Ensure all components are properly tightened according to the manufacturer's specifications.

4. Examine Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and check the fluid level.
2. If low, add the appropriate type of transmission fluid specified in the owner's manual.
3. If the fluid is dark or has a burnt smell, consider a transmission flush.
