4R75W Master Rebuild Kit 2004-2014, new and ready to install. Fits the 4R75W. Ships fast from the USA.
The 4R75W and its later 4R75E name ran behind Ford's V8s from 2004 until the last Crown Victoria, Grand Marquis and Town Car builds. Owners searching for a fix usually see the same things: a puddle under the bellhousing or tailshaft, a slow engagement on cold mornings, and shifts that soften as the fluid warms up. This 2004-2014 listing is the overhaul set pictured in the photo, made up of the pan gasket, valve body and separator gaskets, sealing rings, O-rings and lip seals. It does not show friction or steel plates, so it is the right buy for a reseal or for pairing with clutch packs you already have.
The 4R75W builds more apply pressure than the original 4R70W to handle higher torque, which puts more load on every seal. Line pressure leaves the pump, passes through the valve body and travels down sealed passages into the forward, direct, reverse and intermediate circuits and the servos. A hardened sealing ring on a drum or a shrunk piston seal bleeds that pressure away. The clutch then applies late, slips, and overheats. Because all of these seals age together, a full reseal restores pressure in every circuit at the same time instead of chasing one leak after another.
Two changes inside this year range affect a rebuild. For 2004, ATRA's interchange notes record a new ring gear and output speed sensor that do not interchange with earlier parts, plus a non-magnetic sun shell for the turbine speed sensor. For 2009, ATSG reports that Ford dropped the molded lead frame for a soft wiring harness and new solenoids, and those late parts do not fit earlier cases.
Degrease the case and trace the wet spot to its highest point; a single external seal is a small job. For shift complaints, pull codes, then check the pan. If the magnet is clean, a pressure leak is likely and a reseal is the cure. If it is coated in friction material, you also need clutches, such as the 4R75W master kit with Raybestos clutches. Our Crown Victoria shift problems guide covers the late 4R75E codes and the 2009 harness bulletin, and the Expedition shift problems guide covers the truck side.
This set is listed for 2004-2014 4R75W transmissions, including the units Ford labeled 4R75E. Because the internal electrics changed in 2009 and the hard parts changed in 2004, match the case ID tag and compare the new gaskets with your old ones before assembly, or send us your year and VIN. All related parts are on the 4R70W/4R75W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows the overhaul gasket and seal set without friction or steel plates. For new clutches, see our 4R75W master kit with Raybestos clutches, or contact us to confirm contents before ordering.
The 4R75E is Ford's later name for the same family, and this set is listed for 2004-2014 4R75W units. Compare your case ID tag and old gaskets, or send us the year and VIN to confirm.
Use what your owner guide lists. Earlier units take MERCON V. Ford's 2009 and 2011 Crown Victoria owner guides list MERCON LV.
No. ATSG reports that the 2009 soft harness and solenoids do not retrofit to earlier units that use the molded lead frame.
Often yes, when the delay comes from hardened piston or drum seals letting the circuit drain back. If the clutches are burnt, the frictions must be replaced too.
