Filter assembly for Allison transmissions

The 29530556 filter assembly is a component for Allison transmission systems. It functions to remove contaminants from the transmission fluid, such as metallic particles and debris, to maintain fluid cleanliness. The integrated 35 PSI pressure switch monitors the pressure drop across the filter element, signaling the system when the filter has reached its capacity and requires service.

This assembly is manufactured by Allison and is compatible with various Allison transmission models. The unit features a pressure switch calibrated to activate at a 35 PSI differential, which serves as a diagnostic indicator for maintenance protocols. The assembly is designed to integrate into the transmission fluid circuit to ensure proper filtration and monitoring of the fluid condition.

Transmission filter assemblies are used to prevent debris from circulating through the hydraulic and lubrication circuits of a transmission. By maintaining clean fluid, these assemblies help prevent premature wear on internal components such as clutches, gears, and valves. The pressure switch provides a feedback mechanism that allows operators or maintenance personnel to identify when a filter is obstructed, ensuring that the transmission continues to receive adequate fluid flow and pressure for operation.
