AODE Pump, remanufactured and ready to install. Fits the AODE. Ships fast from the USA.
The AODE was Ford's first electronically controlled version of the four-speed AOD, and it went into full-size cars and light trucks in the early 1990s, including the Crown Victoria, Grand Marquis and Town Car. On a high-mileage example, a worn front pump is a common reason an AODE starts taking its time to engage Reverse, slips across the board, or develops a steady whine that follows the engine. This is a remanufactured AODE pump assembly, ready to install, with a 1-year warranty, shipped from the USA.
The AODE dropped the old AOD's split torque path and went to a conventional lockup converter, so its pump works the same way as the later 4R70W pump that grew out of it. The converter hub engages the pump's inner gear, which turns inside an outer gear in a machined pocket in the pump body. That gear set supplies every pound of line pressure the transmission uses, feeds the converter, and sends oil through the cooler and back as lubrication for the gear train. The stator support is bolted to the pump and carries oil to the forward clutch. Because the electronic controls on the AODE command line pressure through the EPC solenoid, a pump that cannot deliver enough volume leaves the computer nothing to work with.
The AODE shares its valve body design family with the 4R70W, and Sonnax's rebuild sheet for both units shows how pressure regulator valve wear dumps EPC boost oil to exhaust and pump suction, which robs line rise even with a healthy pump. So scan for EPC and solenoid codes, then run a line pressure test. If pressure is low at idle in every range, the pump is the likely cause; if it is normal at idle but will not climb under load, look at the regulator and EPC circuit first. Our 4R70W and 4R75W problems guide covers those valve body failures, which apply to the AODE as well, and the Crown Victoria shift problems guide explains the diagnostic order on the Panther cars.
This listing covers the AODE with no year range printed on it. The AODE arrived around 1992, a year before the 4R70W, and the two were built side by side for years with many shared parts, so the casting on your existing pump is the most reliable match. Sonnax separates 1995-earlier and 1996-later units by valve body alignment pin size and lists early-style pump cover seals for the earlier ones. Compare the old pump with this one, or send us your year and VIN and we will confirm before it ships. Year-specific listings include the 1992-2003 AODE pump and the 1995-2003 AODE pump, and all AODE and 4R70W parts live on the 4R70W/AODE collection page.
An AODE that lost its pump has usually been running hot, so plan on clutches and seals. The AODE master rebuild kit for 1992-1995 covers early units, and the AODE shift kit firms up the shifts and reduces slip time on the new frictions.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 4R70W was developed from the AODE and the pumps work the same way, but parts changed over the years. Match the casting on your old pump, or send us your year and VIN and we will confirm the fit.
Ford used it in early-1990s full-size rear-drive cars and light trucks, including the Crown Victoria, Grand Marquis and Town Car. Check the transmission code on the door tag to confirm you have an AODE.
A new front seal, pump gasket, O-ring and the correct pump cover seals. Inspect the converter hub, flush the cooler, and rebuild the clutch packs if the pan shows friction material.
Use MERCON V. Motorcraft lists it for transmissions previously serviced with MERCON. Set the final level on the dipstick with the fluid hot and the engine idling.
Yes. A bad EPC solenoid or a worn pressure regulator bore causes low or unstable line pressure. Scan for codes and test line pressure before replacing the pump.
