4R70W Pump 1995-2003, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
This remanufactured front pump is built for the 1995 through 2003 Ford 4R70W, the pre-2004 generation found behind V8s in the F-150, Expedition, Navigator, Crown Victoria, Grand Marquis, Town Car and Mustang of those years. If your truck or car now sits a beat too long before Reverse catches, feels soft and slippy in every gear once it warms up, or has a whine that tracks the tachometer, a worn pump is one of the first things to rule in or out. The assembly comes ready to install, carries a 1-year warranty and ships from the USA.
On these units the pump body bolts to the front of the case and the torque converter hub drives its inner and outer gears directly, so oil is being moved any time the engine turns. That flow becomes line pressure for every clutch and band, charge oil for the converter, and the oil that goes out through the cooler and comes back as lube. The stator support is bolted to the pump body and carries passages for the forward clutch and converter circuits. When gear-to-pocket clearance opens up, the pump moves less oil at idle and low speed, which is exactly when these transmissions start to show delayed engagement and heat.
Start with codes, because a failing EPC solenoid on these years produces low, unstable line pressure that feels identical to a tired pump. Then read line pressure with a gauge at idle and under load in Drive and Reverse. Low everywhere suggests the pump; good at idle but no rise suggests the pressure regulator valve or its bore, a well documented 4R70W wear point covered in our 4R70W and 4R75W problems guide. Owners of the sedans should also read the Crown Victoria common problems guide, which collects the fleet and police car failures, and V8 Explorer owners have their own 4R70W Explorer guide.
The year range on this listing matters. Ford reworked the 4R70W for 2004, adding a turbine shaft speed sensor according to Transmission Digest, so 2004 and later trucks should use the 2004-2008 4R70W pump instead. Inside the 1995-2003 window there are still smaller changes: Sonnax identifies 1995 and earlier units by different valve body alignment pins and lists separate early-style pump cover seals for them, so a 1995 owner should match seal type when reassembling. Compare the casting on your old pump with this one, or send us the year and VIN and we will check it. Older 1993-1994 units are covered by the 1993-2003 pump, and the full lineup is on the 4R70W collection page.
With the transmission already out, this is the right moment to replace the solenoids too. The 4R70W shift solenoid and filter kit for 1998-2004 fits the later part of this range, and the 1996-2003 master rebuild kit covers clutches and seals if the pan shows friction material.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This version is listed for 1995-2003. Ford revised the 4R70W for 2004, so 2004-2008 vehicles should use the 2004-2008 pump. Send us your year and VIN if you are unsure.
Sonnax lists early-style pump cover seals for 1995 and earlier units, and the valve body alignment pins differ from 1996-later. Match the seals you remove when you reassemble.
Yes. Scan for codes and test pressure first. A faulty EPC solenoid or a worn pressure regulator bore can cause low or unstable pressure that feels like pump wear.
A front seal, pump gasket and O-ring at minimum. Inspect the converter hub, flush the cooler, and rebuild the clutch packs if the pan shows friction debris.
MERCON V. Prime the pump and partly fill the converter before the first start, then set the final level on the dipstick with the fluid hot and the engine idling.
