Product Description

• The Eaton Fuller A-4740 Air Filter Regulator Assembly is a critical component for diesel truck transmissions. Its primary role is to cleanse compressed air from the vehicle's system and maintain a stable output pressure (typically ~63 psig). This process is vital for the crisp operation of the transmission's range and splitter valves, ensuring smooth and reliable gear changes.
• By delivering clean, dry air, this valve prevents common issues like slow or sluggish shifts, especially during cold starts. It is an essential Eaton transmission part for maintaining the peak performance and longevity of your drivetrain.
