Front and rear planetary carriers, reverse hub, sun gear, ring gear and direct hub for Toyota and Lexus U140E and U240E automatics.
A Camry, RAV4, Highlander, Lexus ES 300 or RX 300 with a four-speed U140-family transaxle that howls in the lower gears and leaves glitter on the pan magnet usually needs more than one gear. This set, reference 27582K, replaces the whole front rotating group in one order: the three-pin front planetary carrier with welded pins, the three-pin rear planetary carrier, the reverse hub, the front sun gear, the front ring gear and the direct hub.
The U140E and its relatives are four-speed transaxles with first through fourth ratios of 3.938, 2.194, 1.411 and 1.019 and a 3.141 reverse. Those ratios come from two planetary sets working together, with the clutches and brakes choosing which sun, ring or carrier is driven or held. The front carrier pinions carry load in every gear below fourth, which is why a failed pinion needle bearing on the front carrier is the classic noise complaint. Once a pinion bearing lets go, the steel it sheds scores the sun gear and ring gear teeth and works into the hub splines, so the neighbors wear out with it.
A U140 whine can also come from a worn oil pump, which sings with engine speed even in Park, so check whether the noise follows engine rpm or road speed. Rule out the common hydraulic complaints too: Sonnax's U140/U240 diagnostic notes cover 2-3 slip and delayed reverse from direct clutch sealing ring wear, which are not gear problems. Our Toyota transmission service guide covers fluid condition and what a dirty pan is telling you. Heavy steel on the magnet plus a road-speed whine points at the planetary set.
The set is cataloged for the U140E, U140F, U240E and U241E. That covers the U140E in the 1999-2001 Lexus ES 300, 1999-2003 FWD RX 300, 2001-2003 V6 Highlander and 2002-2004 V6 Camry; the U140F in the AWD RX 300, AWD Highlander and AWD RAV4; and the U241E in four-cylinder 2002-2009 Camry, Highlander 2.4 and RAV4. Toyota made running changes across those years, so compare carrier pin count, sun gear teeth and hub splines with your old parts, or send us your year and VIN. If only the front carrier is damaged, our single U140E planetary is listed separately. More parts are on the Aisin transmission page.

The three-pin front planetary carrier with welded pins, the three-pin rear planetary carrier, the reverse hub, the front sun gear, the front ring gear and the direct hub, reference 27582K.
It is cataloged for the U240E and U241E as well as the U140E and U140F, which covers the four-cylinder Camry, RAV4 and Highlander 2.4. Compare your old parts or send your year and VIN to confirm.
You can, but when a pinion bearing fails the debris usually damages the sun gear, ring gear and hub splines too. Reusing worn neighbors under a new carrier tends to bring the noise back.
Pump noise follows engine speed and can be heard in Park. Planetary noise follows road speed and changes from gear to gear, usually quietest in fourth.
Use the Toyota fluid listed on your dipstick or in your owner's manual. Earlier U140-family cars generally call for Type T-IV and many later ones moved to WS.
