Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, flashlight.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before working on any electrical components.

2. Inspect Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick and wipe it clean.
Reinsert and remove again to check fluid level and condition (should be bright red and not burnt).
If low, add the manufacturer-recommended transmission fluid.

3. Check Engine and Drivetrain Components

Engine Mounts:
- Visually inspect for cracks or separation.
- If damaged, replace mounts with OEM parts.
Drive Belt and Pulleys:
- Examine for cracks, fraying, or tension issues.
- Replace if necessary, ensuring proper alignment.

4. Inspect Transmission and Differential

Remove the transmission pan (if applicable) to inspect for metal shavings or debris.
Check the differential fluid level and condition.
If grinding noise persists, consider a transmission or differential rebuild or replacement.
