6F35 Pump, new other (see details) and ready to install. Fits the 6F35. Ships fast from the USA.
This is a renewed original Ford front oil pump for the 6F35 six-speed transaxle, cleaned, inspected and pressure tested before it ships. It cross-references the Ford service numbers 9L8Z-7A103-B, -D, -G, -H and -J, the pump assembly numbers that run through the life of the 6F35 in the Escape, Fusion, Lincoln MKZ, MKC and the four-cylinder Edge and Explorer. If you are chasing low line pressure, late engagement, slipping in every gear or a pump whine, or you are mid-rebuild and found a scored pump, this is the factory part rather than an aftermarket copy.
The 6F35 front pump is turned directly by the torque converter hub, so its output follows engine speed. That flow becomes line pressure, which the valve body then divides into clutch apply pressure, solenoid feed, converter charge and cooler and lube flow. Nothing in the transmission works properly if the pump cannot keep up. Wear shows first when the fluid is hot and thin and the engine is at idle, which is why a tired 6F35 pump often feels fine on a cold start and goes soft or slow to engage after twenty minutes of driving.
The pump assembly also carries the stator support tube. Sonnax points out that the OE stator support bushing wears early on the 6F35, and when it does, converter clutch oil escapes and the computer sees lockup slip. That is why a pump can be the hidden cause of a converter clutch code.
Start with the fluid: correct level, correct Mercon LV, no burnt smell. Then measure line pressure at idle and under load, or compare commanded and actual pressure on a scan tool. If pressure is low in every range and the electronic pressure control solenoid checks out, the pump is the likely cause. If only one shift is bad, look at the clutch pack or the valve body instead; our guide to 6F35 transmission problems covers the 3-5-Reverse clutch and valve body faults that are more common than a pump failure.
Ford revised this pump several times, which is why five suffixes share the 9L8Z-7A103 base number, and the 6F35 itself changed to a second generation during 2013. This pump is matched by VIN before purchase, and we recommend you do the same. Send us your year and VIN, or the number cast or tagged on your old pump, and we will confirm it before it ships. If you already know your generation, compare the 2009-up pump with stator casting EXXDA and the other pumps on our 6F35 parts page.
Since the case is apart, replace the filter and pan gasket with the 6F35 filter and pan gasket kit. If the old pump shed metal, budget for a full overhaul with the 6F35 master rebuild kit with valve body.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It cross-references Ford service numbers 9L8Z-7A103-B, 9L8Z-7A103-D, 9L8Z-7A103-G, 9L8Z-7A103-H and 9L8Z-7A103-J. If your old pump or invoice shows one of those, send it with your VIN and we will confirm the match.
It is a renewed original Ford pump: an OEM unit that has been cleaned, inspected and tested, not an aftermarket reproduction.
Ford changed the 6F35 to a second generation during 2013, and the pump numbers changed over time as well. Do not guess. Send us your year and VIN, or the number on your old pump, before ordering.
No programming is needed for the pump. Clearing codes and resetting the transmission adaptive values with a scan tool lets the computer relearn shift pressures on the fresh hydraulics.
At minimum a new front seal, pump seals, filter and Mercon LV fluid, plus a close look at the converter hub. If the old pump failed with debris, the clutches and valve body need attention too.
