JF015E CVT Transmission Valve Body with Solenoids

This is a complete JF015E valve body assembly with the shift and pressure control solenoids already fitted and calibrated, so you are not pulling solenoids off a failed core and hoping they read right. It covers the JF015E CVT, sold by Nissan as the RE0F11A, and replaces OE part numbers 31705-X428B, 31705-X428C, 31705-X428E, 31705-X427D and 31705-X427E. Fitment is the Nissan Sentra 2013-2019 1.8L, Versa 2012-2019 1.6L and Versa Note 2014-2019 1.6L. The manual valve is not included, so carry your original one over.

The JF015E valve body is the part that puts these cars on the hook. Worn solenoid bores and a scored separator plate show up as a judder off idle that a fluid and filter service will not clear, a delayed engagement into drive, RPM flare with no matching road speed, or a straight drop into limp with P0746, P0776, P17F0, P17F1 or P0868 stored. Chasing one solenoid at a time on a CVT rarely holds, because by the time one is out of spec the bore it rides in is already worn. Swapping the whole body puts fresh, tested hydraulics back under the TCU.

Bench work on this one is manageable in the car. Drain the CVT fluid, drop the pan and the filter, then unplug the internal harness at the solenoid body and unbolt the valve body from the case. Before the old unit comes clear, note how the manual valve engages the detent lever pin 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 rather than working around the perimeter, reconnect the harness, and fit a new filter and pan gasket.

Refill with genuine Nissan NS-3 CVT fluid only - these units will judder and set codes on the wrong fluid, and NS-2 is not a substitute in a JF015E. After the refill, clear codes and perform the CVT fluid deterioration reset with a scan tool that supports Nissan CVT functions, then check and set fluid level at the specified temperature window. Skipping the deterioration reset leaves the TCU protecting itself off old data and the car will still feel wrong on the road test.
