4R75W Master Rebuild Kit 2003-2008, new and ready to install. Fits the 4R75W. Ships fast from the USA.
When a 2003-2008 Crown Victoria, Grand Marquis, Town Car or truck with the 4R75W or 4R75E starts slipping into 3rd or 4th, takes a long time to engage Reverse, or leaves burnt fluid and clutch material on the dipstick, the clutch packs are usually finished. This super master kit is built for a complete overhaul of those years. It includes the overhaul gasket and seal set, a friction pack with EXEDY frictions, a steel pack, BorgWarner overdrive and reverse bands, a new filter, a bushing kit, five selective washers, a full set of servo and accumulator pistons and covers, and electrical parts: EPC, TCC and shift solenoids, a harness, and output and turbine shaft speed sensors.
The 4R75W is Ford's heavier-duty version of the 4R70W. It drives through forward, direct, reverse and intermediate clutch packs, holds 4th and Reverse with two bands, and uses servos and accumulators to cushion each apply. Rebuilding with a master kit renews all of it at once: every friction surface, every lip seal and sealing ring, both bands, and the pistons that time the shifts. This kit's piston set covers the overdrive servo, the 2-3 accumulator, the bonded 1-2 accumulator piston and cover, the intermediate servo and the reverse servo cover, which are the pieces that wear their bores and cause soft or harsh shifts.
Pull the pan and look before you buy: a burnt smell and heavy friction material mean the packs are worn out. On 2001-and-later units, Transmission Digest reports that Ford eliminated the two-bolt stiffener plate under the 2-3 accumulator. Without it, the separator plate can bow and leak forward clutch oil into the direct clutch circuit, dragging clutches and burning them again. If your teardown shows burnt direct clutches, plan to correct that valve body area or the new frictions can fail the same way. Our F-150 common problems guide and Crown Victoria common problems guide cover this and the pressure regulator wear that can also burn clutches.
The kit is listed for 2003-2008 4R75W/4R75E units. Two year splits inside that range matter. ATRA documents that the output speed sensor and ring gear changed for 2004 with no interchange, so a 2003 unit and a 2004-2008 unit do not share the same sensor. ATRA also notes the 2004-up sun shell was redesigned and the mechanical diode was updated in 2007. On the electrical side, 1998-2008 units use a molded lead frame with a black case connector, while the solenoids in this kit are described as the soft-harness type with a harness included. Because of that, send us your year, make, model, engine and VIN before ordering so we can confirm the solenoids and sensors match your case. If your unit is a 2009 or later, use the 2009-up 4R75W master kit. All parts for this family are on the 4R70W/4R75W collection page.
A scored or cracked drum should be replaced with the 4R75W clutch drum, and a worn 2004-2008 pump with the 2004-2008 pump.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. 2009 and later units use a different soft harness and solenoids, so order our 2009-up 4R75W master kit instead.
Yes. ATRA documents that the output speed sensor and ring gear changed for 2004 with no interchange, so send us your VIN and we will confirm the sensor matches.
BorgWarner overdrive and reverse bands, along with the servo pistons and covers that apply them.
On 2001-up units the two-bolt stiffener plate under the 2-3 accumulator was removed, which can let forward clutch oil cross leak into the direct clutch circuit.
Mercon V. Ford's 2003 Crown Victoria owner guide lists roughly 13.9 quarts dry fill, or 12.8 quarts with the Police or Handling Package.
