In Jatco/Nissan JF011E (RE0F10A) transmissions, the secondary pulley control valve regulates oil pressure in the secondary pulley circuit. This may cause symptoms including chatter on acceleration, push belt slippage, surface fretting and metal contamination. Low pressure can disable the secondary pulley mechanism, freezing the primary/secondary pulley ratio.
Reconditioning the bore and installing Sonnax oversized secondary pulley control valve kit 113741-19K can restore optimal pressure in the secondary pulley circuit.

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
