Rebuilds the Toyota U240E and U241E four-speed automatic transaxle with new friction plates, steels, gaskets and seals for Camry, RAV4 and Highlander.
If your four-cylinder Camry, Solara, RAV4 or Highlander has started flaring on the 2-3 shift, takes a beat to grab Drive in the morning, or slips when you lean on it up a grade, the four-speed Toyota/Aisin U241E transaxle is the usual suspect. This TRANSPEED master rebuild kit carries the parts a shop reaches for when that unit comes apart: a full set of friction plates, the matching steel plates, and the overhaul gasket and seal set (pan gasket, lip seals, O-rings and sealing rings), all in one box. It is the plain kit without pistons, for a rebuild where your original pistons are still sealing well.
The U240E and U241E are the same four-speed design inside, with ratios of 3.943, 2.197, 1.413 and 1.020; the main difference is final drive (3.120 on the U240E, 2.740 on the U241E). The name matters for ordering: published application data puts the U240E behind the 1.8L in cars like the Celica GT-S and 2003 Matrix XRS, while the 2.4L Camry, RAV4, Highlander and Scion cars carry the U241E. Either way, every gear is a clutch pack squeezed by hydraulic pressure. When friction material wears thin and steels glaze, the pack needs more time and more pressure to hold, and the shift stretches into a flare. Worn sealing rings and lip seals let that pressure bleed off, which speeds the wear. A master kit replaces the wearing surfaces and every rubber or Teflon seal at once.
Start with level and condition, since a low level alone causes flares. Scan for codes, then do a transmission memory reset: GEARS magazine notes that many U-series units with shift complaints had already been rebuilt and were never reset. If a 2-3 flare stays after the reset, voltage-check the shift solenoids at the case connector before blaming the clutches. Our guide on telling a shift flare from a true slip walks through that logic, and Aisin slipping under load covers the pressure-loss side. Burnt fluid plus a consistent slip in one range means the packs are done and this kit is the right buy.
This kit is listed for the U240E and U241E four-speed used behind the 2.4L four-cylinder: Toyota Camry and Camry Solara 2.4L, RAV4 2.4L, Highlander 2.4L, plus Scion tC and xB. Published data lists the U241E for 2002-2005 Camry and Solara four-cylinders, 2001-2007 Highlander 2.4L FWD, front-drive RAV4, 2005-2010 Scion tC and 2008-2015 Scion xB. Later four-cylinder Camry and Solara models moved to the five-speed U250E, and V6 versions use the U151E, so neither is covered. Older product text called the U241E all-wheel drive; application data lists it as front-wheel drive, so check the code on your transmission tag. If you are not sure, send us your year and VIN.

Both. They share the same four-speed internals and gear ratios; the 2.4L Camry, RAV4, Highlander and Scion cars carry the U241E code. Read the code on your transmission tag to be sure.
Application data lists the U241E as a front-wheel-drive unit, and AWD versions generally use a different code. Check the tag or send us your year and VIN before ordering.
No pistons. It holds frictions, steels, gaskets, seals and sealing rings. If your pistons are hard or leaking, use our U240E kit with bonded pistons instead, and buy the filter separately.
No. Five-speed four-cylinder Camry and Solara models use the U250E, which needs a U250E kit.
The rear cover bore where the sealing rings ride, the pump bushing, and the valve body for lockup clutch debris. Any of those can cause pressure loss that burns new frictions.
Use the fluid on your dipstick or in the owner's manual. Earlier units call for Type T-IV and later ones for Toyota WS.
