U760E Planetary 2009, new and ready to install. Fits the U760E. Ships fast from the USA.
A four-cylinder Toyota with the U760E six-speed that has started to hum or whine at cruise, or that left glittering metal on the pan magnet at a fluid service, may need its underdrive planetary set replaced. This is a new aftermarket U760E/U760F underdrive (U/D) planetary gear set built to original-equipment dimensions for the four-cylinder version of Toyota's front-drive six-speed. It arrives as a complete set: gear set, ring gear, pinions and bearings.
The U760E is the four-cylinder member of the same family as the V6 U660E, a six-speed transaxle that makes all of its ratios from two gearsets: a Ravigneaux set and a simple underdrive set. The underdrive set is in the torque path on the way to the counter gear and final drive, so its pinion needles and thrust faces turn under load whenever the car is moving. When those needles wear, the pinions start to rock on their shafts, gear mesh goes out of line, and the noise follows road speed. Left alone, worn pinions shed metal that the filter and every valve in the valve body then have to deal with.
Gears Magazine points out that diagnosing these units means diagnosing the whole drivetrain management system, so scan every module first. A 25 to 50 mph shudder on light throttle is usually the converter clutch, valve body or fluid, not the gearset; Gears suggests driving in Manual 3rd, which disables flex lock-up, to separate those complaints. A planetary problem is mechanical: noise and debris. Pull the pan, look at what the magnet caught, and work through our U660E and U760E problems guide before ordering hard parts.
The listing names this the I4 underdrive set for U760E (2WD) and U760F (AWD), 2009 and up, with interchange reference 166330. Gears Magazine dates the U760E's first use to model year 2010 four-cylinder applications, so treat the 2009 in the name as the start of the part's catalog range and confirm the transmission tag on your unit says U760E or U760F. This is not the V6 U660E set, which carries a different reference and is listed as our U660E underdrive planetary. Match your old set to the photo, or send your year and VIN and we will confirm it. More parts for the family are on our U660E and U760E parts page.
Inspect the old carrier, sun gear splines and the bushings it rode on to find out why it wore; a dry bushing or a starved lube circuit will take out a new set just as quickly. Check end play on the new pinions, and replace thrust washers, thrust bearings and bushings in the area as a matter of course. The U760E/U760F master rebuild kit supplies the frictions, steels and seals, and a worn U760E clutch drum is worth replacing while the unit is open. Flush the cooler and lines so old debris does not return. Refill with Toyota WS fluid, set the level hot using Toyota's T-SB-0036-13 procedure, and clear the adaptive values with a scan tool that actually performs the ECT reset.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing includes the planetary gear set, ring gear, pinions and bearings. Thrust washers, bushings and seals are not included.
No. This is the four-cylinder U760E/U760F underdrive set. The V6 U660E set is a separate part with its own interchange reference.
Gears Magazine says the U760E was first used in model year 2010 four-cylinder applications. Check the transmission tag or send your VIN before ordering for a 2009 vehicle.
Probably not. Gears Magazine ties that shudder to torque converter clutch apply, fluid, valve body or programming. A worn planetary causes speed-related whine and debris.
Toyota WS fluid, with the level set hot per T-SB-0036-13, then an ECT adaptive reset using a scan tool that can perform it.
