Product Description
JF015E Oversized Lockup Control & Plunger Valve Kit
Sonnax Part Number: 33741F-09K
Tooling Required
- F-33741F-TL9
- VB-FIX
In Jatco/Nissan JF015E (RE0F11A) units, the lockup control valve operates under the direct command of the lockup control solenoid routed through a select switching valve and is also influenced via apply and release feedback balance passages. A worn bore, valve spool(s) or plunger valve assembly can cause loss of critical pressure to the sump, lube circuit, or directly into apply or release passages resulting in jerking on coastdown, harsh engagement, and high engine RPM due to no lockup.
Reconditioning the bore and installing Sonnax oversized lockup control and plunger valve kit 33741F-09K restores optimal oil pressure management within the TC clutch apply/release circuits.
- Hardcoat anodized aluminum valve combats premature wear
- Oversized valve reproduces OE pressure regulator function
WARNING: When installed, the head of the retainer for the secondary pulley/pressure regulator valve train stands proud of the valve body casting. The retainer must be remmoved prior to mounting the casting on the VB-FIX to allow the casting to sit flat on the fixture. Sonnax recommends removal of the complete secondary pulley/pressure regulator valve train before mounting the casting on the VB-FIX.
