If the gear fluid is low or contaminated, the metal-on-metal contact make a detrition or growling noise. This is a critical subject that requires immediate inspection to forbid total transmittance failure.

Symptom	Possible Element	Urgency Level
Growling gain with speed	Wheel Heading	High
Growl alteration during turns	CV Joints / Bearings	Eminent
Loud growling during acceleration	Exhaust Leak	Moderate
Growl in neutral or ballpark	Engine Components	Eminent
