4R75W Master Rebuild Kit 2009, new and ready to install. Fits the 4R75W. Ships fast from the USA.
A 2009 or later 4R75E that slips between gears, flares on the 2-3 or 3-4 shift, smells burnt or has clutch material in the pan is usually past a fluid service. This kit is for the late soft-harness version of Ford's 4R75W/4R75E, the transmission behind the 4.6L in the final Crown Victoria, Grand Marquis and Town Car builds. It is listed for 2009-2014 units, and it goes well beyond a gasket and seal set. Along with the overhaul gaskets and seals, a friction pack and a steel pack, it includes both bands, servo pistons, a bushing kit, a selective washer kit and a new filter, plus the late-design EPC solenoid, TCC solenoid, dual shift solenoid assembly, output speed sensor and turbine shaft speed sensor. In other words, it renews every wear item and every electrical part that sits inside the case.
The 4R75W shifts with clutch packs (forward, direct, reverse and intermediate) and two bands, held in sequence by a valve body that takes its orders from solenoids. When clutch packs wear, apply clearance grows, shifts get long and soft, and heat builds until the frictions glaze or burn. A master kit lets you reseal every circuit and renew every pack and band at once. That matters on the 2009-up units in particular because ATSG documents that Ford changed the internal electrics for 2009. The molded lead frame used from 1998 was replaced by a soft wire harness with new solenoids, and none of those parts retrofit to earlier years. Having the correct late solenoids and sensors in the same box saves a second order and keeps the electrical side matched to your case.
Scan for codes and pull the pan before you buy. Varnished fluid and a clean pan point toward solenoid or valve body faults, which a smaller repair may fix. Heavy friction material and a burnt smell mean the clutch packs are done. Our Crown Victoria shift problems guide covers the 2009 harness bulletin and the codes it can set, and the Crown Victoria common problems guide covers pressure regulator wear and the other failures that can mimic worn clutches. Rule those out first so the rebuild fixes the actual cause.
This kit is for 2009 and later 4R75W/4R75E units with the soft internal wire harness, listed for 2009-2014. It will not match a 1998-2008 unit, which uses the molded lead frame and different solenoids; for those years see the 2003-2008 4R75W master rebuild kit. Because friction counts, bushing sizes and sensor lengths changed across this family, compare the parts in the kit to what comes out of your case, and send us your year, make, model, engine and VIN, plus the transmission tag if you can read it. We confirm fitment before the kit ships. Every 4R70W and 4R75W part we carry is on the 4R70W/4R75W collection page.
If the pump shows wear, the 4R75W pump is worth adding, and a cracked or worn reaction shell should be replaced with the 4R75W reaction shell while the unit is apart.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. 1998-2008 units use a molded lead frame and different solenoids, and ATSG notes the 2009 soft-harness parts do not retrofit. Use our 2003-2008 kit instead.
Both bands, servo pistons, a bushing kit, a selective washer kit, a filter, the EPC, TCC and dual shift solenoids, and the output and turbine shaft speed sensors.
No. Have your converter serviced or replaced during the rebuild so old debris does not contaminate the new clutches.
Ford's 2009 and 2011 Crown Victoria owner guides call for MERCON LV. Earlier years used Mercon V, so confirm with your owner guide.
Year, make, model, engine and VIN, plus the transmission tag if it is readable. We check that before the kit ships.
