4R75W Pump 2004-2008, remanufactured and ready to install. Fits the 4R75W. Ships fast from the USA.
The 4R75W is the heavy-duty end of Ford's 4R70W family, and from 2004 on Ford also calls it the 4R75E. You will find it behind V8s in heavier applications such as the Crown Victoria, Grand Marquis and Town Car and many F-series trucks of the period, often doing police, livery or towing work. When the front pump wears, those owners notice a long pause before Reverse catches, slipping that builds as the fluid gets hot, and a whine that follows engine speed. This remanufactured 2004-2008 4R75W pump replaces the worn assembly with a bench-ready unit, backed by a 1-year warranty and shipped from the USA.
The converter hub drives the pump gears directly, so the pump is the only source of line pressure, converter charge oil and cooler and lube flow. The pump body also forms the bore for the intermediate clutch piston, which applies the clutch that holds second gear, and the stator support bolted to it feeds the forward clutch. A worn pump therefore affects engagement, every shift, and how hot the fluid runs.
For these model years the intermediate piston is the late bonded rubber design. ATRA's interchange notes say it is larger than the earlier aluminum piston and produces more holding power, a change that matters most in heavy, high-mileage vehicles that load the second gear clutch hard. 2006 and later units use a one-piece return spring that indexes at 12 o'clock in the case with the springs facing up toward you, while 2004-2005 units use a wave spring on a case seat.
Start with a code scan. The 2004-up unit reads a turbine shaft speed sensor through a non-magnetic sun shell, and ATRA warns that the wrong shell causes harsh or no shifts with ratio and speed sensor codes that can be mistaken for a hydraulic problem. With codes clear, gauge line pressure. Low in every range points at the pump; normal idle pressure with poor rise points at the pressure regulator valve, explained in our 4R70W and 4R75W problems guide. Sedan owners should also read the Crown Victoria common problems guide for the fleet-car failure patterns.
This pump is listed for 2004-2008 4R75W transmissions. Confirm the transmission code on the identification tag or door sticker and compare the old pump to this one, paying attention to the intermediate piston and whether your case uses the wave spring seat or the one-piece spring. If your unit straddles the change, compare against the 4R75W pump for 2003-2008; a light-duty unit uses the 2004-2008 4R70W pump.

A heavy-use 4R75W that needed a pump usually needs the rest refreshed too: the 4R75W overhaul kit for 2004-2014 covers frictions and seals, and if the sun shell is cracked, the 2005 4R75W sun shell is the late non-magnetic style.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
For 2004 and later, yes in practice. Ford introduced the 4R70E and 4R75E names at the start of 2004 production for the updated unit, and this pump is the late design with the bonded rubber intermediate piston. Match it to the pump you remove.
The 4R70W and 4R75W share the same case and pump layout, but you still need to match years. A 2004-2008 pump belongs in a 2004-2008 unit; putting it in an earlier case requires the matching piston and spring as a set and, for the wave spring, its case seat.
Hot fluid thins out, and a worn pump or a leaking pressure regulator bore cannot hold line pressure once it does. Check pressure hot, and look at the fluid. Burnt fluid with friction material in the pan means more than the pump is worn.
MERCON V. Ford's Motorcraft product page lists MERCON LV, SP, ULV and Type F as fluids that must not be used in its place. Fill to the dipstick with the engine running and the fluid at operating temperature.
If the old pump failed with debris, yes, because the converter holds that debris and will feed it straight back into the new pump. At minimum inspect the hub and flush the cooler and lines.
