U151E Clutch Module, new and ready to install. Fits the U151E. Ships fast from the USA.
If your V6 Camry, Sienna, Highlander, Solara, Avalon, RAV4 V6 or Lexus RX330/ES330 has started slipping when you lean on the throttle, flaring between 2nd and 3rd, or smelling of burnt fluid, the friction plates inside the U151E are the first thing a rebuilder checks. This U151E clutch module is a complete new friction pack for the U150E, U151E and U151F family, the five-speed Aisin transaxle Toyota and Lexus bolted behind the 3.0L, 3.3L and 3.5L V6 engines. It replaces the worn, glazed frictions as one matched set instead of buying plates pack by pack.
The U151E reaches its five ratios by holding and driving planetary members with four multi-plate clutches and three brakes. Sonnax's application chart for the unit names them: C1 forward clutch, C2 reverse input clutch, C0 direct clutch, C3 underdrive clutch, B1 2nd brake, B2 low/reverse brake and B3 underdrive brake, plus two one-way clutches. Each of those packs relies on lined friction plates squeezed against steels. When the lining wears thin or burns, the pack cannot hold torque, and the computer sees engine speed rise without a matching rise in output speed. This module supplies the friction plates for those packs. It is frictions only: steels, seals, gaskets, bands and the filter are not included.
Pull the pan first. Friction material in the pan and fluid that smells cooked mean the packs are already damaged, and TransGo's own instructions say a valve body repair alone will not save clutches that are already burned. Clean pink fluid with a slip complaint points the other way, toward pressure control. Check the solenoids and line pressure (a P2714 code is the SLT line pressure solenoid) before opening the case, and read our guide to Aisin slipping under load for the pressure-test order. If the valve body is the cause, a U151E valve body is a cheaper fix than an overhaul.
This friction module is built for the U150E (2002-2003 Lexus ES300), the U151E (2003 and later V6 Camry, Solara, Sienna, Highlander, Avalon, RAV4 V6, ES330 and RX330) and the U151F all-wheel-drive version. Two things trip buyers up. The 2007 and later V6 Camry and ES350, and the 2008 and later Avalon, moved to the six-speed U660E, so those cars need a different pack. And the four-cylinder Camry used the U241E or U250E, not this unit. Read the transaxle code on the case tag or your build sheet, or send us your year and VIN and we will confirm before it ships. You can also browse every part for this family on our Aisin transmission parts page.
Soak every new friction in clean Toyota WS fluid for at least 30 minutes before stacking it. Measure each pack's clearance with a feeler gauge or dial indicator after assembly; Sonnax notes that clutch and brake clearance errors are a common source of shift complaints in this unit. While the case is apart, replace the rear cover sealing rings, inspect the C1 piston for debonding (a 5-4 downshift clunk is the tell), and check the case bearing for spinning, since aluminum debris will hang up valves later. Steels that are blued or warped should be replaced, and a U151E rebuild kit covers the seals and gaskets you will need. Refill with Toyota genuine WS fluid, warm it to roughly 175 F, then reset the transmission memory with a scan tool (a battery disconnect does not do it) and road test through 10 to 15 full upshift and downshift cycles so the computer relearns the new clutches.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the friction plates only. Reuse your steels if they are flat and not discolored, or replace them if they are blued or warped. Seals, gaskets, the filter and bands are also sold separately.
No. Toyota moved the 2007 and later V6 Camry to the six-speed U660E. This pack fits the U150E, U151E and U151F five-speeds, such as the 2003-2006 Camry V6, Sienna, Highlander and Lexus RX330. Send your year and VIN if you are unsure.
The module is listed for the U150E, U151E and U151F. The AWD unit adds a transfer section but shares the clutch packs. Confirm the code on your case tag before ordering.
Toyota WS (World Standard) automatic transmission fluid, the fluid Sonnax specifies when servicing this family. Do not use Dexron or a generic multi-vehicle fluid.
Yes. Reset the transmission memory with a capable scan tool, since disconnecting the battery will not clear it, then drive through 10 to 15 shift cycles. Small flares or a 2-3 overlap during the first few shifts are normal while it relearns.
