U760E Overhaul Kit 2007

If your four-cylinder Camry, Highlander, Venza or RAV4 has a U760E six-speed that leaks, takes a beat to engage on a cold start, or flares between gears now that the miles are up, the seals and clutch apply pistons are the first suspects. This is a new Precision overhaul kit (K75900S) packaged with a new 4-piece set of bonded clutch apply pistons, catalogued from 2007 on. It is the reseal half of a rebuild, plus the pistons that most shops end up replacing anyway once they see how hard the old rubber has become.

What this overhaul kit and piston set do in a U760E

The U760E shifts by sending pump pressure through the valve body to a hydraulic piston behind each clutch pack. On this transaxle the clutch apply pistons are bonded: the rubber sealing lip is molded directly onto the steel piston, so when the lip hardens or cracks you replace the whole piston, not a loose seal. The overhaul kit covers the rest of the sealing system: gaskets, lip seals and the sealing rings that carry fluid into the rotating drums. Together they restore the ability of each circuit to hold pressure. Frictions, steels and the filter are not part of this listing, so plan for those separately if the clutches are worn.

Symptoms that point to tired seals and pistons

• Fluid weeping from the pan, case joint or axle and converter seals
• Slow engagement into Drive or Reverse first thing in the morning that clears up once warm
• Slipping or flared shifts at high mileage, often with dark WS fluid that smells burnt
• A unit that already had clutches replaced but still slips because the original bonded pistons were reused

How to confirm before you buy

Rule out the cheap causes first. Gears Magazine points out that the wrong fluid on this family brings flare complaints and solenoid codes, and that a carboned throttle body or dirty MAF sensor can make downshifts feel harsh even with a healthy transmission. A shudder at light throttle between about 25 and 50 mph is usually torque converter lockup, and selecting Manual 3 isolates it. Set the fluid level hot at the overflow plug the way Toyota specifies, then judge engagement again. If engagement is still late across several ranges, or line pressure is low everywhere, internal sealing is the likely culprit. Our U660E and U760E problems guide walks through those checks and the valve body bore wear that no seal kit can fix.

Fitment

The title says 2007-on because that is where this kit's catalogue range starts, but the vehicles that actually received the U760E arrive from the 2008 model year. The kit maker lists the 2009-2017 four-cylinder Camry, the 2008-2017 Highlander 2.7L, the 2013-2017 RAV4 2.5L, the 2008-2015 Venza 2.7L and the 2011-2016 Scion tC. V6 models use the U660E and need a different kit, and all-wheel-drive U760F units can differ in small sealing details. Read the tag on the transaxle or send us your year and VIN and we will confirm before it ships. Everything else for this family is on the U660E and U760E parts page.

Install notes

• Lubricate each bonded piston lip with fluid or assembly lube and press it squarely into its drum; a rolled lip on install brings back the exact slip you are trying to cure.
• Size the Teflon sealing rings into their grooves before the drums go over them, and air-check every clutch and brake circuit through the case before the valve body goes back on.
• If the frictions are burnt, add a U760E master rebuild kit for frictions and steels; a high-mileage unit also benefits from a U760E solenoid kit while the pan is off.
• Fill with genuine Toyota WS fluid only and set the level hot through the overflow plug, as covered in our WS fluid type and capacity guide. Clear adaptive values with a scan tool and road-test before handing the car back.

What comes in this kit?

A Precision K75900S overhaul kit with gaskets, seals and sealing rings, plus a new 4-piece set of bonded clutch apply pistons. Friction plates, steel plates and a filter are not included.

Why would I replace the bonded pistons instead of reusing them?

On the U760E the piston seal is molded to the piston itself, so a hardened or nicked lip cannot be replaced on its own. Reusing old pistons is a common reason a freshly rebuilt unit still engages late or slips.

Does it fit a 2007 Camry?

Most 2007 Camrys do not use the U760E. The four-cylinder Camry moved to the U760E later, and V6 Camrys use the U660E. Check the transmission tag or send us your VIN before ordering.

Will this fit a 2015 RAV4 or a Scion tC?

Yes, the kit maker lists the 2013-2017 RAV4 2.5L and the 2011-2016 Scion tC with the U760E. Confirm the tag reads U760E, especially on all-wheel-drive RAV4s that may carry the U760F.

What fluid and relearn does it need after the rebuild?

Use Toyota WS ATF only. Fill the unit, then set the final level hot at the overflow plug following Toyota's WS level procedure, reset the transmission adaptive values with a scan tool, and drive it through every gear.
