JF015E Oversized Primary Pulley Regulator Valve Kit
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.
- Hardcoat anodized aluminum valve combats premature wear
- Oversized valve paired with OE spring matches OE pressure regulation algorithm
Symptoms
- Chatter on acceleration
- Damaged valve body casting
- High line pressure
- Low line pressure
- Pulley breakage
- Slips in Forward & Reverse
Cause
Excess bore/valve wear allows circuits to cross-leak which in most instances will exhaust critical oil pressure and volume back to the sump. Wear at the inboard valve spools can contribute to excess primary pulley oil pressure. Wear at the outboard spool can result in low primary pulley oil pressure.
Correction
Restore proper hydraulic operation by reconditioning the bore and installing Sonnax's oversized primary pulley regulator valve kit.
