4R70W Planetary 1992-2003, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
This remanufactured planetary is for the early 4R70W, the version built before Ford redesigned the ring gear for 2004. It is the gearset to look at when a 1990s or early-2000s F-150, Expedition, E-Series, Crown Victoria, Grand Marquis, Town Car, Mustang or Lincoln Mark VIII has developed a speed-related whine, dropped a gear, or started leaving steel on the pan magnet.
Ford introduced the 4R70W for 1993 as a wide-ratio revision of the AODE. Instead of the AODE's 2.40 first gear, the 4R70W gearset gives 2.84 first, 1.55 second, 1.00 third, a 0.70 overdrive and 2.32 Reverse, which is the extra launch and passing grunt these trucks and Panther cars are known for. All of that comes from one compound gearset: forward and reverse sun gears, long and short pinions on a common carrier, and a ring gear tied to the output shaft. The forward, direct, reverse and overdrive clutches and the intermediate clutch choose which part is driven or held. Every gear runs through these pinions, so once their needle bearings or thrust washers wear, the noise follows you through the whole shift pattern.
Through 2003 the output speed sensor reads six holes machined around the ring gear. ATRA's interchange notes say a ring gear from the 2004-up design cannot be used in these earlier units: it produces a sensor signal about four times too fast and the transmission shifts to fourth almost immediately. The planet carrier itself is a different story; ATRA says ratio and dimensions are shared across the years, and the riveted rear cover on older carriers versus the later welded cover does not cause an interchange problem. The output speed sensor also changed from an oval to a square connector in 2001, and ATRA warns that fitting the shorter 2004-up sensor in a 2001-2003 case can give a weak signal and intermittent sensor codes.
Make sure the noise is really the gearset. A whine in Park or Neutral that follows engine rpm is pump or converter. A gearset noise follows vehicle speed and usually changes from gear to gear. Check the magnet and scan for codes; our 4R70W F-150 common problems guide lays out the usual failure order on these trucks, and the Crown Victoria guide does the same for the Panther cars. On the bench, measure pinion end play and feel each pinion for roughness or flat spots.
The listing reads 1992-2003, but the 4R70W itself started with the 1993 model year. A 1992 Ford with a four-speed overdrive automatic has the AODE, whose 2.40 first-gear gearset is a different ratio, so do not treat this as an AODE part. For 1993-2003 4R70W units, including the 2003 Mustang GT and Mach 1 4R75W, read the case tag and confirm your ring gear has the six machined sensor holes. If anything is unclear, send us your year and VIN. For 2004 and later units see the 2004 4R70W planetary, and browse the full range on the 4R70W collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it actually has a 4R70W, which Ford introduced for 1993. A 1992 four-speed overdrive automatic is normally an AODE with a different 2.40 first-gear gearset. Check the case tag or send us your VIN.
The carrier dimensions are shared, but 2004-up units use a different ring gear and output speed sensor, and ATRA says those do not interchange. For 2004-up units use our 2004 planetary listing.
Thrust washers and bearings around the gearset, any worn bushings, the filter, and the clutch frictions if steel debris reached them. Flush the cooler and lines.
Pump and converter noise follows engine rpm, even in Park. Gearset noise follows road speed and often changes from one gear to the next. Steel on the magnet backs up a gearset diagnosis.
MERCON V. Motorcraft recommends MERCON V for vehicles that call for either MERCON V or the older MERCON specification, so it covers the whole 1993-2003 range.
