The JATCO JF011E is an electronically controlled continuously variable transmission (CVT) widely used by Nissan, Mitsubishi, Renault and Chrysler-group vehicles. Manufacturer-specific designations include RE0F10A for Nissan, F1CJA for Mitsubishi 2WD applications and CVT2/CVT2M terminology in Dodge/Jeep applications. The transmission uses a steel push-belt operating between variable-diameter primary and secondary pulleys, together with a torque converter and electronically controlled hydraulic system to provide continuously variable drive ratios. ATSG specifically identifies JF011E, RE0F10A, F1CJA and CVT2 as versions of the same JATCO transmission family.
Specification: Continuously variable transmission (CVT) • JATCO JF011E family • RE0F10A / F1CJA / CVT2M • Steel push-belt drive • Variable primary and secondary pulleys • Torque converter with lock-up clutch • Forward clutch and reverse brake • Electronically controlled hydraulic valve body • Primary and secondary pressure control • Front-wheel-drive and AWD variants • Manual simulated-ratio mode on applicable vehicles • Nissan applications documented with NS-2 CVT fluid • Multiple final-drive and calibration variants depending on vehicle application.
Commonly fitted to selected Nissan Qashqai, X-Trail, Rogue, Sentra and other Nissan models; Mitsubishi Lancer, ASX/Outlander and related applications; Dodge Caliber; Jeep Compass and Patriot; and selected Renault vehicles. Although these transmissions share the JF011E architecture, there are important differences in casings, final drives, valve bodies, electronic calibration and FWD/AWD configuration, so the vehicle VIN, complete transmission code and component identification should always be confirmed before ordering replacement parts.
Common Faults
Common JF011E-family problems include hydraulic pressure loss, valve-body and pressure-control solenoid faults, stepper motor problems, pulley/belt wear, pump flow-control valve wear, torque-converter lock-up faults and primary/secondary speed-sensor problems. Typical symptoms include delayed engagement, slipping, juddering, poor acceleration, abnormal engine RPM, transmission failsafe operation and inability to correctly alter the CVT ratio. ATSG specifically documents pump flow-control valve bore wear causing delayed engagement and slipping, while Nissan diagnostic information documents secondary-pressure solenoid and stepper-motor/ratio-control faults.
