E4OD Pump 1989-1997, remanufactured and ready to install. Fits the E4OD. Ships fast from the USA.
From 1989 through 1997 the E4OD was the heavy-duty automatic in Ford F-Series pickups, Broncos and E-Series vans, behind gas V8s, the 7.3L IDI diesel and, from the 1994.5 model year, the 7.3L Power Stroke. When one of these trucks takes a second or two to grab drive or reverse, slips everywhere when hot, or whines with engine speed, the front pump is high on the list. This remanufactured E4OD pump covers the 1989-1997 span and installs as a finished assembly.
Driven by the torque converter hub, the pump feeds everything: line pressure, converter charge, cooler flow and lube. The E4OD pump body also holds the main regulator and line-to-lube regulator hardware and the converter clutch control valve, so pump wear shows up in shift quality, lockup behavior and fluid temperature together. This year range straddles the biggest pump change of the E4OD era. Ford increased pump output volume for 1995 to deal with the low-RPM flow shortage that let early converter clutches drag. Sonnax lists the pump castings by code (E9, F1, F5 and F8), and its replacement gear sets only fit the 1995-later F5 and F8 E4OD pumps, so a pump from early in this range is not internally the same as one from late in it.
Hook a pressure gauge to the line tap and check idle and stall pressure in each range. Low pressure in all ranges points at the pump or regulator. Because these trucks rely on the electronic pressure control solenoid to command line pressure, rule that circuit out with our EPC solenoid symptoms guide before pulling the transmission. Confirm the cooler flows freely using the cooler line guide. With the pump on the bench, look for scored pockets, worn gear faces and an egg-shaped bushing.
This pump is listed for the 1989-1997 E4OD. Because the internals changed in 1995, read the casting code on your old pump body and cover and match it, or send us the year and VIN and we will confirm before it ships. The solenoid block also changed at 1995 (Sonnax lists separate 1989-1994 and 1995-later blocks), so keep the pump and solenoid block paired for your year. Do not install a 4R100 pump in an E4OD case without checking the stator support, since the 4R100 coast clutch drum journal faces the opposite direction. Narrower ranges such as the 1995 E4OD pump are listed separately, and the full family is on the E4OD and 4R100 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Read the casting code on the pump body and cover. Sonnax identifies E4OD pump castings as E9, F1, F5 and F8, and its gear sets fit only the 1995-later F5 and F8 pumps. Ford also increased pump output volume in 1995.
Not as a straight swap. The 4R100 stator support places the coast clutch drum journal forward for the PTO gear, the opposite of the E4OD, and the solenoid block must match the pump's converter clutch valve design.
Sonnax lists engine stall and stumble on reverse engagement as a symptom of a worn line-to-lube pressure regulator valve, which lives in the pump. A sticking converter clutch control circuit can do the same.
A front seal, gasket, filter and MERCON V fluid at minimum, plus a cooler flush. If the clutches are burned, rebuild the unit at the same time.
It can when low pump pressure or regulator wear is the cause, but codes 62, 628 and 1744 can also come from the converter, solenoid block or wiring. Test pressure before replacing parts.
