Ensure proper pneumatic shift control with the Fuller Filter Regulator Assembly designed for Eaton Fuller transmissions. This aftermarket unit regulates air pressure to approximately 60 PSI for FR and RT series shift systems, supporting correct range and splitter operation. The integrated filter element removes moisture and debris from the supply air before it enters the transmission’s pneumatic circuits. By combining filtration and pressure regulation in one housing, it helps maintain consistent air delivery during repeated gear changes under load. The Fuller A4740 supports stable transmission performance in heavy-duty truck applications.
