This listing is for a genuine OEM Ford 4R100 automatic transmission oil pump assembly. The pump is sourced from an original Ford core and has been professionally resurfaced and fully tested to ensure proper pressure generation and fluid circulation.
During processing, the pump mating surface is precision resurfaced to restore flatness and promote proper sealing. The pump is then bench tested to verify correct operation and ensure it meets functional standards prior to shipment. All components are carefully inspected for wear, scoring, cracks, or damage.
A failing transmission pump can cause delayed engagement, slipping, overheating, low line pressure, or loss of drive. Replacing the pump is critical when rebuilding or servicing a 4R100 transmission to ensure long-term reliability.
