Does this happen with or without pressing on the brakes? Would you describe what kinda vibration is it felt through vibrations.

This is a solenoid issue called slam shift 1-2 if this is what happens and replacement of solenoid is in order here. The VSS AFAIK doesn't have anything to do with slam shift.

How did you see it was making noise when you lifted it up?

This would require someone with more experience to know what is really going on here.

This would indicate a defective Fan Module that is shorted out and will run the fan regardless of what the temp sensor says and will eventually burn out the fan if you don't fix this ASAP. I know from experience.....

Only if there is maintenance history so those reading know where to point to look for other problems related.

REWARD EXCELLENCE!
