4R70W Planetary, new and ready to install. Fits the 4R70W. Ships fast from the USA.
A new gearset is the cleanest fix when a 4R70W starts whining with road speed, loses a range, or turns up a pan full of steel. This is a new planetary carrier for the Ford 4R70W, the wide-ratio four-speed behind 4.6L and 5.4L V8s in the F-150, Expedition, Mustang, Crown Victoria, Grand Marquis, Town Car and Navigator. The listing reference is U76584B. Unlike a used or remanufactured carrier, every pinion, needle bearing and thrust face is fresh, which matters when the old unit came apart under load.
The 4R70W is a revised AODE that went into production in 1993. It keeps the Ravigneaux layout: a short pinion set meshes with the forward sun gear, a long pinion set meshes with the reverse sun gear and the ring gear, and both sets ride on one carrier. Driving or holding different members produces 2.84 first, 1.55 second, 1.00 third, 0.70 overdrive and 2.32 Reverse. In drive-range first a one-way clutch holds the carrier, so first-gear launches put the heaviest load straight through the pinion pins. That is why heavy trucks and police cars wear these carriers first.
4R70W shift complaints are far more often electrical or hydraulic than mechanical. Scan for shift solenoid, EPC and TCC codes and run a line pressure test before you condemn the gear train; the Expedition common problems guide and the F-150 shift problems guide both lay out those checks. Planetary noise follows road speed, not engine speed, so it disappears in Park. On the bench, look for pitted or blued pinion teeth, scored pins and worn thrust washers.
This carrier is listed for the 4R70W without a specific year. According to ATRA, the planetary carrier keeps the same ratio and dimensions through the 4R70E and 4R75E. The only change is the rear cover, which went from riveted to welded, and interchange between years is not a problem. The ring gear is a different story: 2004 and later ring gears use 24 lugs for the output speed sensor instead of six holes, and they do not interchange. This listing is the carrier, so keep your ring gear or match it to your year. Ford also used a stronger gearset in 5.4L applications, so compare pinion count and carrier height with your old part. If your unit is a 2004, see the 2004 4R70W planetary. Send us your year and VIN if you are unsure, and find the rest of the range in the 4R70W collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This listing is the planetary carrier. The ring gear changed in 2004 for the new output speed sensor and does not interchange, so reuse your original or buy the one that matches your year.
ATRA reports the carrier has the same ratio and dimensions in later units, with only the rear cover changing from riveted to welded. Compare it to your old carrier before installing, especially on 5.4L applications that used a stronger gearset.
A failed gearset often leaves the old carrier with worn pins and needle bearings. A new carrier removes that wear from the equation instead of matching used parts.
Heavy loads in first gear, towing, high-power builds, low fluid and debris left after an earlier failure. Worn thrust washers let the pinions move and accelerate the damage.
