U760E Master Rebuild Kit

The U760E is the six-speed automatic behind Toyota's four-cylinder engines, most commonly the 2.5L in the Camry and RAV4. Plenty of these cars are now commuters with very high mileage, and when the transaxle starts slipping on the freeway on-ramp, flaring between gears or taking a second to grab Drive in the morning, the clutches are usually the cause. This master rebuild kit is for the U760E and is cross-referenced to the U760F, the all-wheel-drive version.

What the master rebuild kit does in a U760E

Gears Magazine (ATRA) describes the U760E as the four-cylinder sibling of the V6 U660E, introduced in 2010 for four-cylinder applications. Like its bigger brother it shifts with a small number of clutches and brakes controlled by linear solenoids, and the TCM keeps adapting apply pressure as the frictions wear. That adaptive strategy is why a U760E can feel fine for a long time and then slip in several gears at once: the computer has simply run out of correction. A master kit renews every friction and steel and includes the seals and gaskets to reseal the case, which is the right scope for a high-mileage unit that has already been opened or has burnt fluid.

One difference worth knowing: the case bearing-bore wear that Gears blames on the V6's torque and low first gear is described as a U660E problem. The four-cylinder unit sees less input torque, so a U760E core is more often worth rebuilding, though you should still inspect it.

Symptoms that point to a U760E overhaul

• Flare or slip on upshifts, worst when the fluid is hot
• Delayed or harsh engagement into Drive or Reverse
• Burnt fluid and friction particles in the pan
• Gear-ratio or clutch performance codes after the fluid has been corrected
• Several seal leaks on a high-mileage case
• Converter shudder at 25-50 mph is common on this family too, but it is a lockup issue, not a reason for this kit

How to confirm it before you order

Many slipping four-cylinder Camrys are simply low on fluid or were filled with a generic ATF. The U760E uses Toyota WS, and Toyota's level bulletin for U660E/F and U760E/F units has you set the level hot, between 185 and 194 F, through the overflow plug. Our U660E fluid type and capacity guide explains the procedure, which is the same on this transaxle. If the complaint is a shudder, test it in Manual 3rd as shown in the U660E and U760E problems guide. Also clean the throttle body and MAF before blaming the transmission for harsh coasting downshifts. A real slip with good fluid means it is time to rebuild.

Fitment

This listing is for the U760E, referenced to the U760F, with no specific model years stated. Confirm the transmission tag on your case says U760E or U760F; the V6 U660E looks similar but takes different parts. Internal parts changed during production, so count your plates on teardown, or send us your year, model and VIN to check. Our U660 and U760 family collection page lists every related part, and a U760E/U760F master rebuild kit for Camry, Highlander and RAV4 is also available.

Install notes

• Inspect the U760E clutch drum, bushings and pump for wear and scoring before reassembly.
• Soak frictions in Toyota WS and check clearance on each pack.
• Have the valve body cleaned and checked for bore wear while it is out; Sonnax documents solenoid modulator bore wear on the closely related U660E valve body, so inspect that bore here too.
• Replace the filter and pan gasket, for example with the U760E filter and gasket kit.
• Fill with genuine Toyota WS fluid, then set the level hot through the overflow plug.
• Clear the old adaptive data with a scan tool that runs Toyota's reset, then drive from cold to warm so it relearns.

Which vehicles use the U760E?

It is the six-speed automatic used with Toyota four-cylinder engines, most commonly the 2.5L Camry and RAV4. The U760F is the all-wheel-drive version. Always confirm the tag on your transmission case before ordering.

Will this kit fit a U660E?

No. The U660E is the V6 version of this family and takes its own kit. This listing is for the U760E with the U760F as its cross-reference.

What fluid goes in after the rebuild?

Toyota Genuine ATF WS. Set the level with the fluid at 185-194 F through the overflow plug, as Toyota's WS level bulletin for U660E/F and U760E/F transmissions describes.

What should I replace with the master kit?

The filter and pan gasket every time, plus any scored drum, worn bushing or worn valve body valve. Check the pump and solenoids while the unit is apart.

My Camry shudders at 40 mph. Is this the fix?

Usually not. A light-throttle shudder at 25-50 mph that goes away in Manual 3rd is the converter clutch or lockup valve. Correct the fluid first; this kit is for real clutch slip.

Do I need a scan tool after installing it?

Yes. The learned shift pressures are not cleared by disconnecting the battery. Use a scan tool that runs Toyota's ECT reset, then let the transmission relearn on a drive.
