JF015E, RE0F11A, CVT7, CVT-7 CVT 7

The JATCO JF015E, known as RE0F11A in Nissan applications and marketed as CVT7, is a compact electronically controlled continuously variable transmission (CVT) developed for small front-wheel-drive vehicles. It combines a steel-belt and variable-pulley CVT system with a two-speed auxiliary transmission, providing a particularly wide overall ratio range while allowing the transmission to remain compact and lightweight. JATCO confirms the JF015E as its CVT7 and documents the auxiliary transmission as a defining feature of the design.

Specification: Continuously variable transmission (CVT) • JF015E / RE0F11A • CVT7 family • Front-wheel drive • Transverse installation • Steel-belt variable-pulley system • Two-speed auxiliary planetary transmission • Hydraulic torque converter with lock-up clutch • Electronic transmission control • 150 Nm documented torque capacity • Pulley ratio 2.200–0.550 • Overall ratio coverage 7.3.

The JF015E/RE0F11A is used across a range of compact Nissan, Mitsubishi and Suzuki vehicles, with JATCO directly documenting applications including the Nissan Juke, March/Micra, Note and Magnite, Mitsubishi Mirage and Suzuki Wagon R, among others. Transmission calibration, final-drive ratio and vehicle-specific components can vary by application and production date, so the individual transmission code, vehicle application and VIN should always be confirmed before ordering replacement parts.

Common Faults

Common JF015E/RE0F11A problems include hydraulic pressure loss, valve-body wear, oil-pump wear, pressure-control solenoid faults, pulley and steel-belt wear, auxiliary transmission faults, torque-converter lock-up problems and speed/pressure sensor faults. Typical symptoms include judder or hesitation, delayed Drive or Reverse engagement, RPM flare, slipping under acceleration, erratic ratio changes, transmission warning messages, loss of drive and fail-safe/limp mode.
