U140E Clutch Drum 1999, used and ready to install. Fits the U140E. Ships fast from the USA.
A 2-3 shift that slips or flares, combined with a reverse that is late or missing, is the classic sign of a ring-grooved direct clutch drum in the Toyota U140E. This is a used U140E direct clutch drum with the shaft attached, for the 4-clutch pack, from the 1999-up design and catalogued as interchange 167555A. The 1999 U140E was used in the Lexus ES 300 and the front-drive RX 300; the same drum is also listed for the U140F, U142E and the four-cylinder U240E family, which covers later Camry, Highlander and RAV4 builds.
The U140E is a four-speed front-drive Aisin design, and the direct clutch is involved both in the 2-3 upshift and in reverse, which is why one damaged drum can take out both. Oil reaches the piston through sealing rings that run in ring grooves in a cover. Over time those rings cut into the drum where they ride. Sonnax and Transmission Digest both give the sealing ring to ring land clearance as .003 to .005 inch and say a drum with damage at the ring surface should be replaced, not sanded.
Other faults look similar. A missing or misplaced rubber washer seal between the case and rear cover also bleeds direct clutch oil, and reverse problems can come from a DSL solenoid stuck on, a stuck B2 control valve or damaged B2 seals.
Start with fluid level and condition, then check line pressure in drive and reverse. Normal line pressure with a 2-3 slip and weak reverse points at a direct clutch leak. Transmission Digest suggests a quick split for reverse: with the transmission connector unplugged, a unit that still has no reverse has a hydraulic or mechanical fault, not a computer fault. Our line pressure guide shows the gauge setup, and Aisin slipping under load covers clutch slip diagnosis. At teardown, measure the ring clearance and look at the drum ring surface before reusing anything.
Listed for the U140E, U140F, U142E and U240E from 1999 on. For 1999 specifically, the U140E applications are the Lexus ES 300 and the front-drive RX 300; all-wheel-drive RX 300s use the U140F. This is the 4-clutch direct drum with shaft. It is not our U140E forward drum, which is a 5-clutch drum on a 26-spline shaft, so check the clutch count and shaft before you order. Compare casting marks with the photos, or send us your year, make, model and engine. More parts are on our Aisin transmission page.

It is the direct clutch drum with shaft, for a 4-clutch pack. The direct clutch is involved in the 2-3 shift and in reverse.
The 1999 U140E was used in the ES 300 and front-drive RX 300, and this drum is listed for U140E and U140F from 1999 on. Match the clutch count, shaft and casting marks to your old drum, or send us your year, make, model and engine.
Both use direct clutch oil. When the sealing rings groove the drum or cover, pressure leaks off and both 3rd and reverse suffer. Rule out a missing case-to-rear-cover seal and a stuck B2 control valve or DSL solenoid too.
Sonnax and Transmission Digest both advise against sanding a ring-grooved direct drum. If the ring surface is damaged, replace the drum.
No. Our undated U140E clutch drum is the forward drum with 5 clutches on a 26-spline shaft. This one is the 4-clutch direct drum.
