JF017E Valve Body 2014-2017, remanufactured and ready to install. Fits the JF017E. Ships fast from the USA.
The 2014-2017 Nissan Pathfinder and Infiniti QX60 earned a reputation for CVT judder, and the Murano and Maxima V6 models share the same transmission. If your vehicle vibrates as if driving over rumble strips at 20 to 40 mph, holds high RPM on the highway, or has set a converter clutch code, the JF017E valve body is one of the first parts to suspect. This remanufactured unit, Nissan code RE0F10E, is listed for 2014-2017 vehicles and includes a one-year warranty.
The JF017E was built to handle the torque of Nissan's 3.5 liter V6, with a stronger belt, larger pulleys and a heavier converter than the four-cylinder JF016E. The valve body is bolted to the bottom of the case and controls all of it hydraulically. It regulates line pressure from the pump, sets the pressure applied to each pulley to change ratio and hold the belt, controls forward and reverse engagement, and manages the torque converter. Inside, the lock-up control plunger valve meters converter clutch apply pressure and the converter lube regulator keeps oil flowing through the converter to carry heat away. Both bores wear with mileage, and in a heavy three-row SUV that often tows, they wear faster.
Begin with fluid level and condition. Many judder complaints on these SUVs improve after a correct NS-3 service, so rule that out first. Inspect the pan and magnet: heavy metal means belt, pulley or bearing wear and a bigger repair. With healthy fluid, the next step is a vacuum test of the lock-up and lube regulator bores at the locations published for this valve body family; a bore that fails to hold vacuum confirms the valve body as the cause. Our Jatco CVT problems and fixes guide details the V6 judder pattern, and the CVT failure patterns guide helps you decide whether the damage has spread beyond the valve body.
This valve body is listed for the JF017E in 2014 through 2017 model years, the V6 CVT used in the Nissan Pathfinder, Murano and Maxima and the Infiniti QX60 in that range. It will not fit the four-cylinder JF016E found in the Altima and Rogue. Nissan made running changes to the valve body and solenoid calibration within the JF017E generation, so line up the casting and connector of your old unit with this one, or send us your year, model and VIN for confirmation. Owners of a 2013 or a 2018-2019 vehicle should compare our JF017E valve body for 2014-2019. The full set of parts for this transmission is in the CVT parts collection.
The valve body is reached from below after removing the oil pan. Drain the fluid, clean the pan and magnet, and keep track of the bolt lengths as you remove the old unit. Route the internal harness exactly as it came out and check it for chafing. Torque the bolts to specification in sequence, refill with Nissan NS-3 CVT fluid and check the level hot, then clear codes and complete the TCM relearn with a road test. Owners who tow should strongly consider adding cooling capacity, because heat is what wears these bores. A JF017E filter and gasket kit covers the service items, and if the transmission is coming apart further the JF017E overhaul kit supplies the seals and gaskets.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The V6 Nissan Pathfinder, Murano and Maxima and the Infiniti QX60 in that range use the JF017E. The four-cylinder Altima and Rogue use the JF016E instead.
If the judder comes from wear in the lock-up control or converter lube regulator bores, replacing the valve body addresses the cause. Do a correct NS-3 fluid service first, since some judder complaints improve with fresh fluid.
It is a remanufactured valve body with a one-year warranty.
Yes. The valve body is accessed from below after removing the oil pan, so the transmission stays in the vehicle.
Refill with Nissan NS-3 CVT fluid, check the level at operating temperature, clear codes and run the TCM relearn with a road test.
