Complete JF020E (RE0F12A) CVT valve body with solenoids and harness for the 1.6L Nissan Kicks and Versa, for shudder, slip and pressure codes.
If your 1.6L Nissan Kicks or Versa shudders at light throttle, flares or slips on acceleration, hesitates going into Drive or Reverse, or has thrown a pressure or solenoid code and dropped into limp mode, the CVT valve body is the part behind almost all of it. This is a complete assembly for the Jatco wide-ratio CVT7 W/R that Jatco designates JF020E, with the solenoids and internal wiring harness already mounted, so you are not stripping parts off the old casting to build the new one.
On this small CVT the valve body controls secondary pulley pressure, ratio change and torque converter lock-up, and it carries the linear and pressure-control solenoids the TCM uses to manage all three. When a solenoid sticks or a control bore wears, pulley clamping pressure drops at exactly the moments the car needs it most - light throttle and initial engagement - which is why the symptoms show up as a shudder or judder rather than an outright failure to move.
Nissan's own service bulletins for this CVT family describe a judder trouble code tied to pulley pressure control, with the repair procedure calling for a full fluid and debris check before the valve body is replaced - so confirm your fluid is clean before you order rather than assuming the worst.
Scan for codes first. A pressure-control or linear-solenoid fault with no major metal in the fluid points to the valve body; heavy debris in the pan points to the pulleys or belt instead and a valve body alone will not fix it. Our Jatco CVT problems and fixes guide covers how to read that fluid condition, and our CVT limp mode guide walks through separating a solenoid fault from a mechanical one before you spend money on parts.
This valve body is built for the 1.6L HR16DE-powered 2018-2023 Nissan Kicks and 2020-2024 Nissan Versa. You may see this same unit referred to under more than one transmission code - Jatco's own designation is JF020E, while Nissan's parts system lists a closely related wide-ratio CVT as the RE0F11B - so confirm fitment by the ID tag on your transmission case or by running your VIN through a Nissan parts catalog rather than by the code alone. See our full CVT parts collection for fluid, filters and other CVT hardware we stock across makes.
Drain the CVT fluid, drop the pan and pull the strainer, then unplug the harness connector at the case before removing the valve body bolts. Note the length and position of each bolt as you pull them, since several lengths are used across the casting, and lower the valve body off flat rather than prying a corner. Clean the case mating surface and the pan magnet, install the new assembly, and torque the bolts in the factory sequence. Refill with genuine Nissan CVT-3 NS-3 fluid or the equivalent Idemitsu Type N3 fluid and set the level at operating temperature - this CVT does not tolerate a generic or off-spec fluid. After installation, clear codes and run the CVT learning procedure with a Nissan-capable scan tool; skipping it can leave a harsh engagement or a lingering shudder even with a good valve body installed. Our adaptive relearn guide covers why that step matters on electronically controlled units like this one.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Jatco, the manufacturer, designates this wide-ratio CVT7 W/R as the JF020E, while Nissan's own parts system lists a closely related unit as the RE0F11B. Confirm which one is in your car using the ID tag on the transmission case or your VIN, not the code alone.
Shudder or judder at light throttle, flare or slip accelerating from a stop, delayed or harsh engagement into Drive or Reverse, and stored pressure-control or linear-solenoid codes with limp mode.
The solenoids and internal wiring harness are already mounted on this assembly, so you install it as a complete unit rather than swapping solenoids over from the old casting.
Genuine Nissan CVT-3 NS-3 fluid or an equivalent NS-3 specification fluid such as Idemitsu Type N3. A generic or off-spec CVT fluid is not correct for this unit.
This valve body is built for the 1.6L HR16DE Kicks and Versa (2018-2023 Kicks, 2020-2024 Versa). Earlier Versa and Sentra models used a different CVT family, so confirm fitment by the case ID tag before ordering.
Yes. Clear the codes and run the CVT's learning or relearn procedure with a Nissan-capable scan tool, or the car can still shudder or shift harshly even with a good valve body installed.
