RE0F21A, N-CVT
-
JATCO RE0F21A (N-CVT) – a compact continuously variable automatic transmission (CVT) developed by the Japanese manufacturer JATCO and used in small cars since the late 1990s. It is designed for cars with transversely mounted small-displacement petrol engines and front-wheel drive (FWD). The transmission is best known from the Nissan Micra / March, the Nissan Cube and certain Fiat Punto Speedgear versions.
The RE0F21A design uses a hydrodynamic torque converter with a lock-up clutch, two variable-diameter pulleys and a steel drive belt, which provides smooth changes in the transmission ratio without conventional fixed gears. An electronic-hydraulic control system regulates the pulley positions, the belt clamping pressure and the torque converter operation according to engine load and driving conditions. A planetary gear set with hydraulically actuated clutch elements is used to select forward and reverse.
The transmission was designed for economical operation in small city cars. Depending on the variant, the final drive ratios, torque converters, control components and transmission housings differ. For example, Nissan Micra K11 versions with CG10DE and CGA3DE engines used RE0F21A variants with different final drive ratios. Some related CVT versions used an electronic mode that simulates fixed transmission ratios.

Alternative and related designations:
- Nissan / JATCO: RE0F21A, N-CVT, NCVT.
- Transmission parts catalogues: CVT0; JF012E – linked to the RE0F21A in some professional catalogues, but it cannot be considered a universal synonym for all variants.
- Fiat: Speedgear, DLTC46FHJ1AA – designations of specific related CVT versions.
Vehicle model examples (only the corresponding CVT versions; fitment depends on production year, engine, market and the exact transmission code):
- Nissan Micra / March: second generation (K11, approx. 1998–2002), 1.0 l CG10DE and 1.3 l CGA3DE petrol engines, certain N-CVT versions. The RE0F21A transmission is directly documented in the Nissan factory service manual.
- Nissan Cube: first generation (Z10, approx. 1998–2002), 1.3 l petrol engine, certain front-wheel-drive CVT versions for the Japanese market, including CGA3DE engine variants.
- Fiat Punto: second generation (188, from 1999), certain 1.2 l petrol Speedgear CVT versions. JATCO transmission variants structurally related to the RE0F21A were used; their component compatibility must be checked separately.
Important: the RE0F21A transmission was produced in several variants whose hydraulic control units, solenoids, pulleys, steel belts, torque converters, filters, housings, differentials and electronic control components may differ. The RE0F21A must not be automatically identified with the JF012E, RE0F05A, RE0F06A or later JATCO CVT transmissions. The manufacturer documentation for the Nissan Micra K11 specifies Nissan CVT Fluid NS-1 for this transmission, but specifications for other vehicles and variants must be checked individually. Before ordering spare parts, the vehicle's VIN, exact transmission code, variant and original OE number must be checked.
