Within the trans components - manual there are hoses and pipes. These parts are designed to fit a specific Fiat 500L, ensuring a snug fit within the transmission housing. They are constructed for fluid to move through these elements and help the automobile shift between gears, allowing the car to stop or idle.
If the hoses and pipes of your Fiat 500L transmission are worn or cracked, fluid will leak out of the system. Without the right fluid pressure, your transmission can slip out of gear and eventually burn up. Checking these parts when conducting routine maintenance will help you avoid serious engine failure.
