Solution

1. Preparation

Tools Required: Mechanic's stethoscope, socket set, transmission dipstick.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Serpentine Belt and Components

Sub-steps:
1. Remove the engine cover (if equipped) using a socket set.
2. Visually inspect the serpentine belt for cracks, fraying, or glazing.
3. Check the tensioner and idler pulleys for wear or play.
4. Replace any worn components with OEM parts as necessary.

3. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it, then remove it again to check the fluid level.
3. Inspect the fluid color; it should be a clear red. If it is dark or has a burnt smell, replace it.
4. If low, add the manufacturer-recommended transmission fluid until the proper level is reached.

4. Inspect and Secure Exhaust System
