4R75W Overhaul Kit, new and ready to install. Fits the 4R75W. Ships fast from the USA.
The 4R75W and its 4R75E successor are the heavy-duty end of Ford's 4R70W family, found behind the 5.4L in the Expedition, in E-150 vans and in Police Interceptor Crown Victorias that spend their lives idling and then running hard. When one of those units has been cooked by towing, a loaded van or police duty, this master rebuild kit gives you every soft part for a 2004-and-later rebuild in one order: the seal and gasket overhaul set, 19 friction plates, 18 steel plates, a pan filter and band material, as pictured.
Ford rated the 4R75W for more torque than the 4R70W by beefing up hard parts, but the clutches still live in the same fluid. Heat is the killer. A van at full payload or an Expedition pulling a camper keeps fluid temperatures high for hours, the friction lining glazes and the piston seals harden. Once a seal stops holding, the clutch it applies slips, makes more heat, and the cycle speeds up. A rebuild with fresh frictions, steels and seals resets the whole unit, provided the hard parts and valve body are sound.
A rebuild only lasts if the cause of the failure is fixed too. Measure line pressure and look at the cooler: a restricted cooler or a worn pressure regulator valve will burn the new clutches as fast as the old ones. Sonnax's vacuum test guide ties no 4th, a 4-3 neutral and a burnt overdrive band to overdrive servo regulator valve wear, and ties soft shifts and premature clutch failure to the main pressure regulator. Our Expedition common problems guide covers the towing-related failures, and the Expedition shift problems guide explains how to separate a valve body fault from worn clutches.
The kit is listed for 2004-and-later units: 2004-2014 E-150 vans with the 4.6L or 5.4L, 2004-2006 Expedition, 2004-2011 Crown Victoria including police cars, and 2004-2010 F-150. ATRA documents that the 2004-up 4R75E got a larger bonded rubber intermediate piston in the pump, a non-magnetic sun shell so the input speed sensor can read the forward drum, and a new ring gear and output sensor. Those changes are why a 2003-and-earlier 4R75W should not be rebuilt with this kit. If you have an early unit, look at the 2003-2014 4R75W overhaul kit or the 1996-2003 overhaul kit, and send us your VIN if you are not sure which you have. The full 4R70W and 4R75W collection lists every part for this family.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
For 2004-and-later units the soft parts are shared across the 4R70E/4R75E family, which is why this kit lists both. What matters most is the model year: 2004-up units changed the pump intermediate piston, sun shell and ring gear, so year decides the kit.
No. A 2003 Expedition 4R75W predates the 2004 changes. Use the 2003-2014 or 1996-2003 overhaul kit and confirm with your VIN.
No. It contains the seal and gasket overhaul set, 19 frictions, 18 steels, a filter and band material as pictured. Drums, bonded pistons, bushings and the converter are separate.
Flush or replace the cooler, check the valve body's pressure regulator and overdrive servo regulator bores, and fit an auxiliary cooler if the van works hard. Heat is what burned the original clutches.
Follow the owner guide for your year. Ford lists MERCON V for the 2008 Crown Victoria and MERCON LV from 2009 on.
