4R75W Shift Kit 1991-2008, new and ready to install. Fits the 4R75W. Ships fast from the USA.
The 4R75W is the heavier-duty member of the 4R70W family, and it ends up behind engines that work hard: police Crown Victorias, livery Town Cars, and trucks that tow. When one of those starts flaring on the 2-3, banging on a kickdown, or cracking separator plates, this TransGo shift kit is the valve body repair. It is listed here for 1991-2008 units because the kit covers the whole AODE-based family from 1991 on, and the 4R75W versions of that family through 2008 are the ones this page is about.
A 4R75W lives a harder life than a passenger 4R70W, so TransGo gives it its own numbers. The separator plate holes that control clutch apply rates are drilled larger for police, taxi and heavy-duty use, and police and truck builds get a white idle boost spring. On police and taxi calibrations the kit also makes a jack-rabbit launch start in second for about one wheel turn, which takes the shock off the low roller clutch and driveline. Every build gets the EPC relief system, a new solenoid regulator valve and the forward clutch circuit fixes that protect the overdrive band.
Fleet cars rack up harness and connector faults, so check codes and solenoid resistance before blaming hydraulics; 1998-on units use the black hard-wire frame inside the case. Our Crown Victoria shift problems guide covers the police and fleet failures in detail, and the Expedition shift problems guide covers truck use. If the electrical side passes and the shifts still flare or bind, open the valve body.
This kit fits 4R75W and 4R75E transmissions through 2008, and TransGo's own coverage of the family starts in 1991. Inside that span the parts changed. From 2001 the valve body lost its bolt-down plate near the 3rd accumulator, and those units can crack the separator plate there; the kit supplies a spacer for the retainer so the plate can be reused. 2004-up units with factory plastic forward clutch rings keep their originals. Match your separator plate to the instructions, or send your year, model and VIN and we will confirm it for you. The full range is in the 4R70W and 4R75W parts collection.
For a full refresh while the unit is out, the 4R75W banner rebuild kit 2004-2017 covers the friction and seals, and a 2005-2008 filter and gasket kit finishes the pan service.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
TransGo uses one kit for the AODE, 4R70W and 4R75W family. The difference is in the instructions: heavy-duty, police and taxi builds get larger plate holes and a white idle boost spring.
On police and taxi builds, TransGo notes a hard launch will start in second for about one turn of the wheels to protect the low roller and driveline. Normal starts are unaffected.
From 2001 the plate near the 3rd accumulator is no longer clamped by a bolt-down plate, and the retainer point can crack it. The kit includes a spacer that lets you reuse the plate.
This listing is for units through 2008. Ford changed the internal harness and solenoids for 2009, so send us your VIN if you have a later vehicle.
MERCON V for 2008 and earlier. Check the level hot in park after the install and road test.
