AODE Pump 1994-2004, new and ready to install. Fits the AODE. Ships fast from the USA.
Plenty of Ford owners and parts counters still call the 4-speed overdrive automatic in their Crown Victoria, Grand Marquis, Town Car, Mustang or F-150 an AODE, even when the tag reads 4R70W. This new pump is listed for AODE-family transmissions from 1994 to 2004. If the car sits in gear a moment before it moves, flares in every range once it is warm, or hums at idle in step with the engine, the front pump is one of the first parts to check. It arrives new with a 1-year warranty.
The AODE was the electronically controlled successor to the AOD, and Transmission Digest notes the 4R70W followed it by about a year on the same layout. In both, the converter hub turns the inner gear of a gear-type pump housed in the front pump body. That gear set is the only source of pressurized oil in the transmission. It feeds the pressure regulator, which sets line pressure for the clutches and bands; it charges the converter; and it pushes fluid out to the cooler and back as lube for the bushings and planetary gears. The bolted-on stator support also carries the forward clutch feed, so a damaged pump assembly can drop forward clutch pressure as well as overall line pressure.
Rule out the electrical side first. EPC and shift solenoid faults are well known in this family and can make pressure low or erratic with a healthy pump. Then check line pressure with a gauge in Drive and Reverse. Low at idle, especially with noise and bushing debris in the pan, points to the pump. Normal at idle but flat under throttle points to the valve body. The 4R70W and 4R75W problems guide walks through the pressure checks, and the Crown Victoria common problems guide covers the sedan-specific failures that send these cars to the shop.
The listing covers 1994-2004. Because the AODE name gave way to 4R70W on most vehicles during these years, go by the transmission code on the door sticker or the tag on the case rather than by name alone. Two details from ATRA's interchange notes are worth checking on the old pump. First, the late units use a bonded rubber intermediate piston while earlier pumps use an aluminum piston; the two styles interchange only as complete pumps. Second, the late stator support uses thin plastic forward sealing rings where the earlier W design uses cast iron rings, so use the ring type that matches the support. Compare bolt pattern, piston style and stator support with what you remove, or send us your year and VIN to check. All of the pump ranges and hard parts for this family are on the AODE and 4R70W parts page.
A pump that failed from contamination usually means the clutches and cooler are dirty too. In that case an AODE overhaul kit and a cooler flush protect the new pump.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 4R70W grew out of the AODE on the same layout, and this pump is listed for both names in the 1994-2004 range. Go by the tag on your transmission and match the intermediate piston and stator support to your old pump.
Possibly. ATRA notes the late support uses thin plastic forward rings while the earlier W design uses cast iron rings with the same outside size. Use the ring type that matches the support you install.
MERCON V. Prime the pump before first start, then set the level with the transmission at operating temperature.
Often. A worn pump bushing lets the converter hub move, which wears the seal quickly. Check the hub surface too, since a grooved hub will ruin a new bushing and seal.
A front seal and pump gasket at minimum. If you had solenoid codes, add the solenoid kit; if the fluid was full of debris, plan on an overhaul kit and a cooler flush.
