JF017E Oversized Primary Pulley Reducing Valve Tool Kit

Includes Reamer, Guide Pin and Reamer Jig

Requires VB-Fix (not included)

In Jatco/Nissan JF017E (RE0F10E) units, the primary pulley reducing valve controls and maintains oil pressure to the primary pulley actuator as influenced by the primary pulley solenoid. A worn bore or valve spool can cause loss of oil pressure control to the primary pulley actuator resulting in: chatter on acceleration, high or low pressure at the primary pulley actuator, pulley breakage and slippage in Forward and Reverse. Reconditioning the bore and installing Sonnax oversized primary pulley reducing valve kit 33510N-04K restores optimal oil pressure to the primary pulley actuator.
