Common Causes of Transmission Fluid Smells
- Leaking Transmission Fluid⁚ A leak in your transmission, cooler lines, or seals can cause fluid to drip onto hot engine components, leading to a burnt odor.

- Contaminated Transmission Fluid⁚ Foreign substances like water or debris can contaminate the transmission fluid, causing a foul smell.
- Failing Transmission⁚ A failing transmission can release burnt fluid, usually accompanied by other symptoms like slipping gears, rough shifting, or strange noises.
