In Jatco/Nissan JF015E (RE0F11A) transmissions, the primary pulley regulator valve controls oil pressure in the primary pulley circuit. A worn bore or valve spool can cause loss of oil pressure control in the primary pulley circuit. Symptoms that may indicate degraded primary pulley pressure control are loss of higher gear ratios and high or low primary pulley pressure. Reconditioning the bore and installing Sonnax oversized primary pulley regulator valve 33741F-02K can restore optimal oil pressure in the primary pulley circuit.
