U760E Solenoid Kit 2013-18

A 2013-18 four-cylinder Toyota with a U760E six-speed tends to show its age the same way: an upshift that flares when hot, a lockup shudder that comes and goes, or a pressure solenoid code that returns after every clear. This new solenoid kit replaces the complete set of shift and pressure-control solenoids for the later years of U760E production. Many of these transaxles now have high mileage, and their original solenoids have spent that whole time cycling in aging fluid.

How the solenoids run a late U760E

The U760E is the four-cylinder member of Toyota and Aisin's front-drive six-speed family, introduced for 2010. Its computer does the work a hydraulic governor once did: linear solenoids ramp each clutch on and off during a shift, a dedicated solenoid sets line pressure, another meters lockup, and an on/off solenoid moves a shift valve. Because these are pulse-width-modulated, the valve ends and the bores they ride in see continuous motion. This kit, shown as seven pieces, contains six linear solenoids and one bracket-mounted on/off solenoid.

Symptoms that point to this kit

• Pressure or shift solenoid performance codes that return after clearing
• Shift flare or slip on upshifts once the transmission is at operating temperature
• Shudder between roughly 25 and 50 mph during light-throttle lockup
• Bang into gear from Park or Neutral
• Limp mode with a fixed gear and a lit warning lamp

Diagnose before you replace

On these units a solenoid code is the start of the diagnosis, not the end. Toyota solenoids almost always fail mechanically from contaminated fluid rather than with an open coil, so an ohmmeter will not clear them. Work in this order:

• Scan every module and fix engine faults first; carbon on the throttle body or a slow MAF signal changes the transmission's pressure strategy.
• Check fluid level hot at 185-194°F and confirm WS fluid is in it.
• Use Manual 3, which turns off flex lockup, to tell a converter shudder from an engine miss.
• Run Toyota's Check Mode with a capable scan tool so intermittent codes set on the first drive.

The full sequence, plus the valve body bores that must be checked, is in our U660E/U760E service guide. If the solenoid modulator or lockup control bores are worn, the new solenoids will be fed the wrong pressure; a U760E shift kit addresses that while the valve body is out.

Fitment

Listed for the U760E, 2013-18. Within that window the U760E is the four-cylinder unit; V6 models of the same vehicles used the U660E and need a different kit. Toyota moved some models to newer transmissions during these years, so check the transmission ID on the case and compare the connector colors and solenoid count against the photo, or send us your year and VIN to confirm. Earlier-year U760E kits and the V6 versions are on the U660E/U760E collection.

Install notes

• With the pan and strainer removed, inspect the solenoid harness and pins; a cracked or brittle harness causes the same codes as a bad solenoid.
• Look at the old solenoids' valve ends and screens. Heavy varnish or metal points to a fluid or hard-parts problem that new solenoids will not fix.
• Use new lubricated O-rings and tighten the solenoid bolts evenly to avoid cocking a solenoid in its bore.
• Refill with Toyota WS (00289-ATFWS) and set the level at temperature through the overflow plug.
• Clear all codes and reset the ECT learned values with a scan tool; then drive from cold to hot so the transmission relearns.

When the fluid shows clutch material, plan for a full overhaul with a U760E master rebuild kit instead of solenoids alone.

Will this fit a V6 Camry from these years?

No. The U760E is the four-cylinder unit. V6 versions use the U660E, which takes a different solenoid kit. Check the ID on the transmission case or send us your VIN.

Should I replace the solenoids or the whole valve body?

If the valve body bores are worn, especially the solenoid modulator and lockup control valves, new solenoids alone may not cure the problem. Compare the cost of a complete valve body with solenoids plus labor before deciding.

What causes these solenoids to fail?

Degraded fluid and debris. Toyota solenoids rarely fail electrically; the valve ends wear or stick, which is why fluid condition and mileage matter more than a resistance test.

Can I clear the adaptive learning by disconnecting the battery?

No. The transmission memory is non-volatile. Use a scan tool that can run Toyota's ECT reset, and do not cross the battery cables, which can damage modules.

Which fluid is correct?

Toyota WS ATF, part number 00289-ATFWS, with the level set at 185-194 degrees F through the overflow plug.
