JF017E Pressure Control Solenoid, new and ready to install. Fits the JF017E. Ships fast from the USA.
The JF017E is the heavy-duty CVT8 that Jatco built for Nissan's 3.5-liter V6, and it sits behind the 2013-2018 Pathfinder and Altima V6, the 2015-2018 Murano and Quest, and the 2014-2018 Infiniti QX60. When one of those starts to judder at light throttle, flare on a hard pull, or hold the tach high in limp mode, the pressure controls on top of the valve body are one of the first things a shop checks. The product photo for this item shows a complete set of those controls: four linear solenoids with long ported spools, one bracket-mounted solenoid with a short black nozzle, and two pressure sensors, one with a grey plug and one with a black plug. You get every plug-in electrical part on the valve body in one order.
Gears Magazine's teardown of this unit points out what changed from older Nissan CVTs: there is no stepper motor and no ratio control arm any more. Ratio is controlled entirely by pressure. The line pressure solenoid regulates pump output, and separate primary and secondary pressure solenoids set the clamping force on each pulley so the belt holds while the ratio moves. Those three are the same part, which is why they look identical in the photo. The select solenoid is different and controls forward clutch and reverse brake apply. All of them are normally high, so a coil that loses its signal defaults to high pressure rather than none. The two sensors tell the TCM what primary and secondary pressure actually are. A V6 puts a lot more torque through the belt than the four-cylinder JF016E does, so a lazy solenoid on this unit tends to show up as slip under load before anything else.
On a 2013 JX35 or 2014-2016 QX60 with judder codes, Infiniti bulletin ITB15-012e sets out the inspection order, and Nissan has an equivalent bulletin for the V6 Pathfinder and Altima. Check the speed sensors next: Gears notes that all of the JF017E speed sensor connectors are the same, and swapping the primary and secondary plugs during a repair sets pressure solenoid and ratio codes on a healthy transmission. Then check the coils themselves. The linear solenoids should read 5.5 to 8.5 ohms and the TCC solenoid 6.1 to 7.7 ohms. A coil far outside that range is bad; all coils in range with codes still present points to valve body wear. Our Nissan CVT problems guide and harsh and delayed engagement walkthrough help sort out which you have.
For the JF017E (Nissan RE0F10E) behind the 3.5-liter V6 only. Four-cylinder Altimas and all Rogues use the JF016E; see the rest of our CVT parts collection for that unit. Gears warns that pressure sensor colors vary and recommends staying with the color you removed, so compare your sensors and connectors against the photo before ordering, or send your year and VIN and we will confirm.
Drain the fluid, drop the pan and strainer, disconnect the harness and remove the valve body. All of the solenoid grounds run through the valve body, so clean the mounting surfaces and brackets before fitting the new parts. Use fresh O-rings lubed with fluid, put each sensor back in its original position, and torque the brackets evenly. Refill with Nissan NS-3 CVT fluid such as genuine NS-3 and set the level at the specified temperature with a scan tool. If the bores are worn, a complete JF017E valve body saves a second teardown, and the 7-piece CVT8 solenoid kit is another way to source the same group of parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 3.5-liter V6 versions of the 2013-2018 Altima and Pathfinder, the 2015-2018 Murano and Quest, and the 2014-2018 Infiniti QX60, plus the 2013 JX35.
According to Gears Magazine those three linear solenoids are the same part. The select solenoid and the TCC solenoid are different.
The linear solenoids should read 5.5 to 8.5 ohms and the TCC solenoid 6.1 to 7.7 ohms at the valve body.
Stay with the colors you removed unless the valve body was set up for a different sensor. Mixing them can leave the TCM reading the wrong pressure.
