Complete overhaul kit for the Toyota U340E/U341E 4-speed: friction and steel plates, bonded pistons, filter, gaskets and seals for a full rebuild.
When the U340E automatic in a 2000-2005 Toyota Echo finally wears out, the signs are hard to miss: it flares on the 2-3 shift, takes a beat to grab Drive, and leaves a burnt smell on the dipstick. If it has reached that stage, this master overhaul kit covers the full teardown and includes the parts a basic kit leaves out. Along with the friction plates, steel plates, seals and gaskets, you get bonded clutch pistons, a new oil filter, the pan gasket and the separator plate gaskets for the valve body. It cross-references to Toyota kit numbers 35330-0W020, 35330-0W021 and 35330-20020, and to kit T14400A.
The U340E uses the same four-speed gearset as its 1.8L twin, the U341E: 2.847 first, 1.552 second, 1.000 third and a 0.700 overdrive. It gets those four ratios by applying clutches and brakes with hydraulic pistons. The valve body routes pressure to each piston through a separator plate that has its own gaskets. That matters for a rebuild. A clutch pack is only as good as the piston that squeezes it and the gasket that seals its feed passage, so this kit renews the pistons and the separator plate gaskets along with the frictions. When the clutches have burned, the pistons and seals around them have taken the same heat.
Check the fluid and the pan magnet against our ATF color and smell chart. If the codes keep coming back on clean fluid, test the solenoids first. Our guide to bench testing transmission solenoids covers resistance and flow checks. Transmission Digest has shown that a P0770 on this transaxle family can come from the lockup solenoid circuit rather than a worn clutch. A good solenoid with burnt fluid and slipping, though, means the clutches are done. If you are deciding between this kit and a replacement unit, our rebuild vs replacement cost guide lays out the tradeoffs.
Listed for the U340E and U341E four-speed front-drive automatic: the 2000-2005 Toyota Echo 1.5L, the 2009 Toyota Corolla 1.8L, and Japan-market 1.5L Toyotas including the Allion, Premio, Platz, Porte, Belta and Probox. The Echo uses the U340E. The 1.8L Corolla uses the U341E, and Toyota fitted the Corolla with other transmissions in other years, so a model year alone does not settle it. Read the code on the transmission tag or the build information first. If you are unsure, send us the year and VIN. Matching valve bodies are in our Aisin transmission collection.

Yes. The kit includes the oil filter and pan gasket along with the frictions, steels, bonded pistons, separator plate gaskets, seals, O-rings and sealing rings.
The Echo for 2000-2005 uses the 1.5L and the U340E, which this kit is listed for. Check the code on the transmission tag before you order.
No. It is listed for the 2009 Corolla 1.8L, which uses the U341E. Corollas from other years used other transmissions, so match the code on the tag or send us your VIN.
Only if the clutches are actually worn. P0770 points to the lockup solenoid circuit first. Test the solenoid and wiring, and rebuild the unit when the fluid is burnt and it slips.
