JF010E JF011E RE0F09A/B RE0F10A Oversized Lockup Control Valve Kit | Sonnax

In Jatco/Nissan JF010E (RE0F09A/RE0F09B) and JF011E (RE0F10A) 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 valve kit 113741-22K restores optimal oil pressure management within the TC clutch apply/release circuits.

• Hardcoat anodized aluminum valve combats premature wear
