K313 CVT Transmission Valve Body for Toyota Corolla

A remanufactured valve body for the Toyota K313 continuously variable transmission, the belt-and-pulley CVT behind the 2014-and-later Corolla. Listed fitment covers Corolla 1.6L, 1.8L and 2.0L from 2014 on, plus the Allion and Auris 1.2L applications sold outside the US.

The valve body controls line pressure to the primary and secondary pulleys and the lock-up and forward/reverse clutches. When the bores wear or a valve sticks, the symptoms are harsh or delayed engagement into Drive or Reverse, a flare or RPM surge under light acceleration, belt slip feel, and pressure-related codes that come back after a fluid service. Replacing the valve body is far cheaper than a full CVT assembly when the belt and pulleys are still good.

Bench notes: confirm K313 on the transmission tag first. Drain the fluid, pull the pan and strainer, and transfer the solenoids from the old unit only if the new body is supplied without them. Torque the bolts in the factory sequence, install a new pan gasket and strainer, and refill with Toyota CVT Fluid FE, checking level at the overflow plug at the specified temperature. Run the CVT learn procedure with a scan tool afterward.
