Remanufactured JF017E (RE0F10D) CVT valve body with solenoids, filter and gasket for Nissan Altima, Maxima, Murano, Pathfinder, Quest and Infiniti QX60 3.5L.
This is a remanufactured JF017E CVT valve body for the Nissan 3.5L V6, with the filter and pan gasket included so the whole hydraulic service gets done in one pan drop. Buyers usually find it after a Pathfinder or QX60 starts shaking pulling a load, a Quest flares on the highway, or a Murano or Maxima sets a P0776, P0778 or P17F1 that a fluid change did not clear.
The JF017E is the high-torque member of Jatco's CVT8 family, the same design as the four-cylinder JF016E but rated for V6 torque. In a CVT the valve body does more than pick a gear. It sets how hard the primary and secondary pulleys clamp the steel belt at every moment, it shifts the ratio by moving oil into one pulley and out of the other, and it controls apply and release of the torque converter lockup clutch. The pressure control solenoids bolted to it turn TCM commands into those pressures. A solenoid and the bore it feeds wear together, and on a heavy V6 that pulls a trailer or a full minivan, losing a little clamping pressure turns into belt slip and judder quickly. That is why a calibrated assembly is the usual repair rather than one solenoid.
Nissan's judder bulletin for the related four-cylinder Altima and Rogue unit shows the logic: a felt judder plus P17F1 means pull the valve body, look at the belt, and replace the valve body if the belt is clean. P17F0, or a belt with slip marks, means the transmission itself has to be replaced. The bulletin does not formally cover the V6 cars, but the same reasoning applies. A judder code with a clean belt and pulleys points at hydraulics. Metal paste in the pan or a marked belt points at a unit. Our Jatco CVT Nissan problems and fixes guide covers this split in more detail. If the main complaint is a delayed engagement, see the harsh or delayed engagement guide first.
Listed for the 3.5L V6 in the 2013-2018 Nissan Altima, 2016-2019 Maxima, 2015-2019 Murano, 2013-2018 Pathfinder, 2015-2017 Quest and 2014-2016 Infiniti QX60. Reference numbers include 31705-29X6D, 31705-29X0A, 31705-29X0B, 31705-29X0E, 31705-29X1A, 31705-29X1B, 31705-29X1E, 31728-29X0D and 31397-1XF0D. Nissan revised this assembly several times, so look up the number on your old valve body or send us the year and VIN. A 2.5L car with the same model name has the smaller JF016E, which will not take this part. The CVT parts collection lists the other CVT8 hard parts.
Drain the fluid, pull the pan, unplug the harness connector, and remove only the valve body bolts. Nissan marks them on the four-cylinder sister unit, so check the service manual for your bolt pattern. Install the new filter and gasket from this kit, torque the bolts evenly, and fill with genuine NS-3 CVT fluid, checking the level at temperature. The step people skip is calibration. Every CVT8 valve body carries its own solenoid calibration data, and the TCM needs that data loaded with a capable scan tool or the shift and lockup control will be off. If the converter clutch is part of the complaint, a JF017E 7-piece solenoid kit is a good spare to keep on hand, and a high-mileage unit getting opened up may also need the JF017E pump to bring line pressure back.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This valve body is for the 3.5L V6 JF017E. The 2.5L Altima and the Rogue use the JF016E, which has a different valve body.
Yes. The TCM needs the calibration data for the new valve body, written with a scan tool that can perform Nissan CVT calibration. Without it, pressure and lockup control will not be correct and judder can come back.
Genuine Nissan NS-3 CVT fluid. Set the level with the fluid at operating temperature, as the service procedure calls for.
Only if the belt and pulleys are still good. A judder code with a clean belt and no metal in the pan points to the valve body. Slip marks on the belt or heavy metal debris mean the transmission needs internal repair or replacement.
The number is stamped or labeled on the valve body itself. Compare it to the reference numbers listed on this page, or send your year and VIN and we will confirm before you order.
