Burning transmission fluid can produce a distinct and unpleasant odor. It is often described as a burnt or acrid smell, similar to that of overheated or burning oil. The smell may become more noticeable when the transmission is under heavy load or during prolonged driving. If you detect a strong burning smell resembling transmission fluid, it could indicate an issue with your transmission, such as overheating, low fluid levels, or worn-out components. It is advisable to have your vehicle inspected by a qualified mechanic to diagnose and address any potential problems with the transmission.
