Level 10 Hydrosystem™ Recalibration optimizes the drivability and improves the shift feel. Transmissions used in heavy-duty applications, such as Recreational Vehicles, Sport Utility Vehicles, vehicles that carry heavy loads, and vehicles that pull heavy trailers will have well controlled shifts that maximize drivability and minimize heat build-up and wear in the transmission and wear-and-tear on the vehicle. Transmissions used in high performance applications, such as street rods and race cars with high horsepower, turbocharged, or supercharged engines, will have firm, positive, tire-blazing shifts that optimize acceleration and minimize heat build-up and wear in the transmission.
