This valve kit addresses problems attributed to loss of solenoid regulator pressure control in Jatco/Nissan JF015E (RE0F11A) transmissions. Issues commonly associated with a malfunctioning solenoid regulator valve in these CVT units are: noise on acceleration, chatter on acceleration, push belt slippage, increased push belt and pulley wear, low line rise, low solenoid feed pressure and no ratio change. Reconditioning the bore and installing Sonnax oversized solenoid regulator valve kit 33741F-03K can eradicate the listed symptoms with proper solenoid feed oil pressure regulation.

Hardcoat anodized aluminum valve combats premature wear
Oversized Sonnax valve installed with OE spring restores OE pressure
