Full overhaul kit for the Ford 4R75W with Raybestos friction and steel clutch modules, molded pistons, bushing kit, washer kit and pan filter.
This master rebuild kit is built for the later Ford 4R75W, 4R75E and 4R70E, the 2004-and-newer versions of the 4R70W family found behind the 4.6L and 5.4L V8 in full-size trucks, SUVs and the Crown Victoria, Grand Marquis and Town Car. If your unit is slipping into third or fourth, flaring on the 2-3 shift, engaging late when hot, or the pan is full of dark fluid and friction paste, this is the kit for a complete overhaul. What sets it apart from a basic soft-parts kit is the clutch content: Raybestos friction and steel clutch pack modules, plus molded pistons, a bushing kit and a washer kit in the same box.
The 4R75W is a four-speed overdrive automatic with a Ravigneaux gear set. Five clutch packs (forward, direct, reverse, intermediate and coast) and two bands do the shifting, and each clutch is applied by a piston sealed against its drum. On high-mileage units the problem is often not only worn friction material. The old bonded piston lips harden and start to bypass, so a clutch loses apply pressure and slips even while it still has lining left. Molded replacement pistons put a fresh, correctly sized sealing lip on every circuit. Pairing new frictions with new steels in matched modules also avoids the classic mistake of stacking fresh linings against glazed, heat-blued steels that will glaze the new frictions within weeks.
Check fluid level and condition hot, scan for codes, and put a gauge on line pressure before committing to a teardown. Electrical faults can mimic slipping: a failed speed sensor or a power feed problem to the solenoids sets codes and erratic shifts with good clutches. Our 4R70W Crown Victoria shift problems guide covers those electrical and valve body checks, and the Expedition common problems guide explains how heat and towing wear out clutches in the heavier trucks. Once the pan shows friction flakes and metal, the unit needs to come apart and this kit is the right starting point.
The listing covers 2004-and-up 4R75W, 4R75E and 4R70E units. It is not a substitute for a 1992-2003 4R70W or AODE, which use different clutch counts and earlier hard parts. 2004 matters because ATRA notes that year changed the ring gear and output speed sensor design and moved to a non-magnetic sun shell that the turbine speed sensor reads through, and none of it interchanges with earlier units. Ford also changed the later units: per ATSG, 2009-up 4R75E transmissions went back to a soft internal wiring harness with new solenoids, and Ford's owner guides call for MERCON LV in the 2009-and-later Crown Victoria, where the 2008 used MERCON V. Read the ID tag on the case, count the frictions in your old packs against the kit, or send us your year and VIN and we will confirm it. If you have a 2004 4R70W instead, see the 2004 4R70W master rebuild kit, and every version is on the 4R70W and 4R75W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is listed for 2004-and-up 4R75W, 4R75E and 4R70E units. Earlier 4R70W and AODE transmissions use different clutch counts and hard parts. Use one of the 1998-2003 4R70W master kits instead, or send us your year and VIN.
The original bonded piston seals harden with heat and start to bypass fluid, which causes slipping even when the frictions are not fully worn. New molded pistons restore a proper seal on every clutch circuit so the new frictions get full apply pressure.
Use what your vehicle specifies. Ford owner guides list MERCON V for 2008 and earlier 4R75E applications such as the Crown Victoria, and MERCON LV for 2009 and later. Check your owner guide or the dipstick before filling.
Inspect the pump and replace it if the gears or body are scored, and replace the shift solenoids if they are original. On 2001-and-later valve bodies, also repair the forward-to-direct cross leak so the new direct clutch does not burn.
It renews the direct clutch frictions, steels and piston that usually fail with that complaint. If the cause was a valve body cross leak or worn pressure regulator, fix that too or the new direct clutch can burn again.
Clear codes and reset the transmission adaptive values with a scan tool, then road test through all gears at light and moderate throttle so the computer can relearn shift timing.
