K310 Solenoid Kit 2006-2013, new and ready to install. Fits the K310. Ships fast from the USA.
Owners of 2006-2013 Toyota models with the 1.5L or 1.8L CVT, such as the Corolla Axio, Allion, Premio and Auris, usually find this page after the car starts to shudder at light throttle, flare the revs without pulling, or lock itself in a single ratio with the warning light on. This is a new five-piece solenoid set for the K310 and its 1.8L sibling, the K311, so you can replace every solenoid on the valve body at once instead of guessing which one is weak.
The K310 is an Aisin-built belt-and-pulley CVT that Toyota started producing in 2006 for its 1.5 to 1.8 liter cars. There are no fixed gears to select. The transmission computer changes the ratio by moving hydraulic pressure between the two pulleys, holds the belt with clamping pressure, and engages the forward and reverse elements and converter lockup through the same valve body. The solenoids are the computer's hands on that hydraulic system. The two larger linear solenoids in this set modulate pressure in fine steps, and the three smaller ones handle the switching jobs. When one of them sticks or loses its calibrated response, the computer sees the actual ratio or pressure drift away from what it commanded and protects the belt by limiting power or holding one ratio.
Old or wrong fluid causes many of the same complaints, so check fluid condition and level before buying parts. Read the codes and note whether they name a specific solenoid circuit; measure that solenoid's resistance at the valve body and at the module to rule out the harness. Belt and pulley wear also causes slip that new solenoids will not cure, so if the fluid is full of metal, plan a bigger repair. Our CVT slipping under load guide and CVT limp mode guide walk through separating a hydraulic fault from a mechanical one.
This set is listed for the K310 and K311 from 2006 to 2013. The K310 is the 1.5L version, used for example in the NZE141 Corolla Axio, and the K311 is the 1.8L version. These are mostly Japanese-market and international models, so the transmission code on the tag is the thing to match, not the vehicle name. Toyota later replaced this design with the K313 on many models, and the K313 uses its own solenoid layout and fluid; if your tag reads K313, use the K313 shift solenoid kit instead. Compare your old solenoids to the photo, including connector shape and mounting tab, or send us your year and VIN. You can also browse our full CVT parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Five: two larger linear pressure-control solenoids and three smaller solenoids, as shown in the photo. That covers the solenoid set on the K310/K311 valve body.
No. The K313 is a later design with its own solenoid layout and fluid. Use the K313 solenoid kit if your transmission tag reads K313.
The K310 is the 1.5L version of Toyota's 2006-on Aisin CVT, used in models such as the NZE141 Corolla Axio. The 1.8L version is the K311. Most are Japanese-market or international vehicles, so check the tag on the transmission.
They can when the shudder comes from a sticking lockup or pressure solenoid. Shudder from worn pulleys, a stretched belt or burnt fluid will not go away with solenoids alone, so check the fluid first.
Toyota CVT Fluid TC, unless your owner's manual says otherwise. Never use conventional ATF in this transmission.
A scan tool is needed to clear codes and, on models that require it, to reset CVT learned values. The fluid level check also depends on reading fluid temperature.
