Understanding your vehicle's HEV Transaxle Fluid and the importance of its maintenance
HEV Transaxle Fluid enables your transmission's ratio changes through hydraulic pressure and to protect internal components against wear while still allowing sufficient friction between belt and pulleys to transfer your engine's torque to the wheels. Over time, heat and contaminants can cause HEV Transaxle fluid to lose the necessary properties. It is recommended to inspect the transmission for any leaks, check the fluid regularly and change the fluid at the specified intervals.
