Fitment And Identification

This pump gear set is intended for transmission assemblies that use the inner O-ring-style inner gear. Confirm the original gear design, inner gear tooth count, and transmission identification before ordering.

The A4LD family includes multiple related versions and design changes. This gear set should not be selected based solely on vehicle make, model, or year. Compare the removed inner gear to verify it uses the O-ring-type configuration.

Rebuild Guidance

Replace scored, worn, damaged, or heat-discolored pump gears during transmission overhaul. Inspect the pump body, pump cover, bushing, stator support, seals, converter hub, and related hydraulic components before assembly. A pump gear set is not represented as a guaranteed correction for delayed engagement, slipping, low line pressure, or other undiagnosed transmission concerns.

Transmission hydraulic and shift concerns can originate from multiple areas, including pump wear, valve body wear, solenoid circuits, internal seals, clutch assemblies, bands, or converter-related problems. Proper diagnosis is recommended before installing replacement parts.

Fluid Service

Refill with the transmission manufacturer’s specified ATF after service. Lubegard ATF Protectant may be considered when compatible with the application and used according to its product directions; it does not replace necessary mechanical or hydraulic repair.
