4R75W Master Rebuild Kit, new and ready to install. Fits the 4R75W. Ships fast from the USA.
If your Crown Victoria, Grand Marquis, Town Car, F-150, Expedition or Navigator has the 4R75W and it now flares between gears, engages Reverse late once it is hot, or shows dark fluid with friction paste in the pan, patching one circuit rarely holds. This 4R75W master rebuild kit is for the owner or shop that is taking the transmission out and wants every wear item renewed in one pass, so the rebuilt unit starts its next life with fresh clutch packs and fresh seals instead of a mix of new and tired parts.
The 4R75W is the heavier-duty member of Ford's 4R70W family: a four-speed rear-wheel-drive automatic with electronic shift, EPC pressure and converter clutch control. Power flows through the forward, direct, intermediate and reverse clutch packs, while the overdrive and reverse bands hold their members for 4th and Reverse. A master kit replaces the parts those circuits depend on: the friction and steel plates that do the actual holding, and the piston seals, sealing rings and gaskets that keep apply oil where it belongs. When those rubber and Teflon pieces harden, pressure bleeds off before it reaches a pack, and the plates slip and burn even with a healthy pump.
Check the fluid level and condition first, then pull the pan. A clean pan with bright red fluid usually means the problem is electrical or in the valve body, not the clutches; scan for solenoid and EPC codes and work through our Crown Victoria shift problems guide before committing to a rebuild. Heavy friction material, a burnt odor or metal on the magnet means the hard parts need inspection and the packs are done. If you are diagnosing a truck, the F-150 common problems guide walks through the same family's known failures, including the forward-to-direct cross leak that Transmission Digest traced to the 2001 removal of the two-bolt stiffener plate under the 2-3 accumulator. A rebuild that ignores that leak can burn new direct clutches.
This listing is for the 4R75W and is not tied to a single year range, which means you need to confirm your unit before ordering. The 4R75W came along in the 2003-and-later era, and ATRA documents a ring gear and output speed sensor change for 2004 with no interchange, plus a redesigned 2004-up sun shell. Ford also moved 2009-and-later units back to a soft internal harness with different solenoids. Gaskets and seals follow the case and pump castings, so match your casting and pan style, or send us your year, model, engine and VIN and we will check the kit against your build. If your unit is a 2009 or later, the 2009-up 4R75W master kit is the safer match, and a 2003-2008 build with worn bands, servos and sensors may be better served by the 2003-2008 super master kit. Everything for the family is on the 4R70W/4R75W collection.
Teardowns often turn up a worn pump or a cracked drum. Replace them with the 4R75W pump for 2003-2008 and the 4R75W input drum while the case is open.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Confirm first. 2009-up units returned to a soft internal harness with different solenoids, so we recommend our 2009-up 4R75W master kit for those years. Send your VIN if you are unsure.
The 4R70W and 4R75W share a basic layout, but clutch counts and some hard parts differ by version. Send us your year and VIN and we will confirm before you order.
Check the pan first. If the fluid is burnt and full of friction material, the packs are worn and a rebuild is the right move. If the fluid is clean, test the EPC and shift solenoids and the valve body before tearing it down.
Mercon V for 2008 and earlier. Ford's 2009 and later Crown Victoria owner guides call for Mercon LV, so follow the guide for your year.
Any scored drum, worn pump or damaged planetary, plus a cooler flush and a converter service. Reusing contaminated parts is the most common reason a fresh rebuild fails early.
