Transmission fluid wears out over time and can become contaminated with dirt and grit. Additionally, burned transmission fluid results from transmission heat – and transmission heat results from low fluid or old, ineffective fluid that needs to be changed.

What happens when transmission fluid burns?

Overheated or low transmission fluid could be a potential source of this burning smell. Fresh transmission fluid tends to smell sweet or tart. When that smell turns burnt, your transmission fluid has broken down and the system is burning too hot, leading to an increase in friction and corrosive activity in the engine.
