U140E Clutch Drum, used and ready to install. Fits the U140E. Ships fast from the USA.
A Toyota or Lexus with a U140E that is slow to pick up Drive, flares when it should be pulling in first, or slips forward while reverse still feels normal often has a forward clutch problem. This listing is a used U140E forward clutch drum: the 5-clutch drum on a 26-spline shaft with an aluminum piston, cleaned, inspected and tested, and it comes with its used steels and clutch plates in place. The U140E is the four-speed front-drive Aisin unit used in the 1999-2001 Lexus ES 300, 1999-2003 front-drive RX 300, 2001-2003 Highlander V6, 2002-2004 Camry V6 and the 2009-2013 Corolla.
The forward clutch (C1 in Toyota terms) is the clutch that connects the input shaft to the gear train when you pull the lever into Drive. Its drum holds the five-clutch pack and the piston, and fluid reaches that piston through sealing rings on the shaft. The drum shaft is splined to the input side, which is why the 26-spline count matters when you match a replacement. The Sonnax U140/U240 diagnostic chart ties the C1 accumulator to the neutral-to-Drive engagement, so a leak at this drum shows up first as a soft, late or harsh N-D engagement.
Not every late Drive is the drum. A weak C1 accumulator spring, low fluid, a failing pump or a sticking valve can mimic it, so pressure-test before you pull the unit.
Check the fluid level hot and smell the fluid for burnt clutch material. Then put a gauge on the line pressure tap: normal pressure in Drive with a slow or slipping engagement points at a leak inside the forward circuit, while low pressure everywhere points back toward the pump or regulator. Our line pressure guide walks through the gauge setup, and Aisin harsh or delayed shifts covers engagement complaints on these units. On the bench, air-check the forward circuit and look closely at the sealing ring lands before you reuse the old drum.
This drum is listed for the U140E and U140 family, with interchange also shown for the U241E, U151E, U151F and U250. Those later five-speed and four-cylinder units were built with revised internals, so treat that interchange as a starting point, not a promise. Before ordering, compare your old drum: count the clutches (this one is a 5-clutch pack), count the shaft splines (26), and check the piston and casting marks against the photo. If you are unsure, send us your year, make, model, engine and VIN and we will check it. This is not our U140E direct drum with shaft, which is a 4-clutch drum tied to the 2-3 shift and reverse. More parts are on our Aisin transmission page.
The drum is used, tested and ready to install, and it ships fast from the USA.

It is the forward clutch drum: a 5-clutch drum on a 26-spline shaft with an aluminum piston. The forward clutch is what engages Drive.
Yes, it comes with its used steels and clutches installed. For a full rebuild most builders still install a new friction and steel pack and new seals.
The U140E was used in the 2002-2004 Camry V6, 2001-2003 front-drive Highlander V6, 1999-2001 ES 300 and front-drive RX 300. All-wheel-drive versions use the U140F. Match the 5-clutch count, 26-spline shaft and casting marks to your old drum, or send us your year, make, model, engine and VIN.
A forward clutch leak is a common cause, but low fluid, a weak C1 accumulator spring or a pump problem can cause the same delay. Check fluid level and line pressure first.
Use the Toyota fluid your manual lists, Type T-IV on earlier units or WS on later ones, check it hot, and reset the learned values with a scan tool so the ECM relearns engagement and shift timing.
