Remanufactured and dyno-tested JF015E CVT valve body with solenoids for Nissan Sentra, Versa and Versa Note judder, flare or limp mode.
A Nissan Sentra, Versa or Versa Note that judders off idle, flares in RPM with no matching road speed, hangs before it engages Drive, or has dropped into limp mode is almost always pointing at the JF015E valve body. This is a complete remanufactured JF015E valve body with the shift and pressure control solenoids already fitted and calibrated to the housing, so you are installing a tested assembly instead of guessing whether a pulled solenoid is still within spec.
The JF015E (sold by Nissan as the RE0F11A) is a continuously variable transmission with a separate sub-gearbox ahead of the pulleys, and the valve body is what makes it drivable. It routes line pressure through precision bores and spool valves to the pulleys and the sub-gearbox clutches, and it carries the solenoids the TCU uses to time every ratio change and every low-to-high shift. ATSG's technical writeups on this unit note how easily small mechanical issues on the JF015E - a bent exciter ring finger, a cracked sensor housing - turn into pressure swings and false converter-clutch codes, which is why a worn or contaminated valve body shows up as a drivability complaint long before it shows up as a measurable leak.
Chasing one solenoid at a time rarely holds on this unit, because by the time one reads out of spec the bore it rides in is usually already worn, and fine metal shed during the transmission's own break-in can make valves stick intermittently rather than fail outright.
Scan for stored codes and note whether the belt and pulleys show signs of slip - Gears Magazine's JF015E writeup points out that pressure and performance codes on this transmission often trace back to a worn flow control valve in the pump or a sticking valve body bore rather than belt damage, so pull the pan and check for metal before condemning the pulleys. If your symptom is judder or a solenoid/ratio code with no history of belt slip, this valve body is the correct repair. Our JF015E service kit has the filter, gasket and fluid you'll want on hand for the same job.
This valve body is built for the JF015E as installed in the Nissan Sentra 2013-2019 1.8L, Versa 2012-2019 1.6L and Versa Note 2014-2019 1.6L, and it replaces OE numbers 31705-X428B, 31705-X428C, 31705-X428E, 31705-X427D and 31705-X427E. The manual valve is not included, so carry your original one over from the old unit. Nissan ran more than one valve body layout across this production span - our later updated-style JF015E valve body and early exposed-solenoid JF015E valve body cover different model-year windows, so compare the connector and solenoid layout on your old unit against the photos before ordering.
Drain the CVT, drop the pan and filter, unplug the internal harness at the solenoid body, then unbolt the valve body from the case - note how the manual valve engages the detent lever pin before the old unit comes clear so you seat the replacement the same way. Set the new body on the case dowels, run the bolts down in a cross pattern to spec, reconnect the harness, and fit a fresh filter and pan gasket; pair the install with a JF015E clutch pack kit if the fluid showed heavy wear debris. Refill with Nissan NS-3 CVT fluid only - NS-2 is not a substitute and will set codes in this unit - then clear codes and run the CVT fluid deterioration reset with a scan tool that supports Nissan CVT functions before judging the shift feel on the road.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The shift and pressure control solenoids are already fitted to the valve body and calibrated to it, so you are not pulling solenoids off a failed core and hoping they test within spec.
No. The manual valve is not included with this valve body, so carry your original manual valve over from the unit you are replacing.
P0746, P0776, P17F0, P17F1 and P0868 are the codes most associated with JF015E valve body and solenoid wear, along with judder off idle, RPM flare with no road speed increase, and a delayed engagement into Drive.
The Nissan Sentra 2013-2019 1.8L, Versa 2012-2019 1.6L and Versa Note 2014-2019 1.6L, replacing OE numbers 31705-X428B, 31705-X428C, 31705-X428E, 31705-X427D and 31705-X427E.
Nissan NS-3 CVT fluid only. NS-2 is not a substitute in this unit and will cause judder and false codes.
Yes. Run the CVT fluid deterioration reset with a scan tool that supports Nissan CVT functions, then check and set fluid level at the specified temperature before judging the shift feel.
