Industrial K313 CVT Automatic Transmission Valve Body

Description:

The K313 CVT Automatic Transmission Valve Body is used in Toyota continuously variable transmission systems to control hydraulic pressure distribution for gear ratio changes, clutch engagement, and torque converter lock-up operation. Commonly installed in Toyota Corolla, Corolla Cross, and other 1.8L–2.0L K313 CVT-equipped vehicles where electronic solenoid control is required for smooth and efficient transmission performance. Transmission technicians, OEM rebuilders, and automotive repair shops use this valve body for CVT overhaul, shift quality restoration, fault code repair, and replacement of worn or malfunctioning hydraulic control assemblies.

Applications:

The K313 valve body is commonly used in Toyota CVT systems including Corolla 1.8L and 2.0L platforms where hydraulic control of primary and secondary pulley pressure, line pressure regulation, and transmission ratio control are required to maintain fuel efficiency, drivability, and smooth acceleration in compact and mid-size passenger vehicles.
