JF017E Solenoid Kit 2016-2019, new and ready to install. Fits the JF017E. Ships fast from the USA.
A 3.5L Murano, Pathfinder, Altima V6 or Infiniti QX60 from the later JF017E years that flares between ratios, slams into Drive, or drops into fail-safe with a pressure solenoid code usually has a control problem, not a chain problem. This new JF017E solenoid kit for 2016-2019 is built for that repair. As pictured, it arrives as a complete valve body with the solenoids, both pressure sensors and the internal wiring harness already mounted, including the long harness lead that runs to the case connector. That means one bolt-in assembly instead of hunting down which solenoid or which worn bore is causing the fault, and it is backed by a 1-year warranty.
The JF017E is Jatco's heavy-duty CVT8 variant built for 3.5L engines, and it drives the pulleys with a chain instead of a push belt. It dropped the stepper motor and ratio control arm used on the older JF011E, so every ratio change is made purely with hydraulic pressure. Three identical linear solenoids handle line pressure, primary pulley pressure and secondary pulley pressure. A separate select solenoid controls the forward clutch and reverse brake for engagement, and a pulse-width TCC solenoid controls converter lockup slip. Two pressure sensors on top of the valve body tell the TCM what the pulleys are actually getting. When any of those drift, the chain is clamped harder or softer than the TCM asked for and the computer reacts.
Scan the TCM, not just the engine computer, and compare commanded and actual primary and secondary pressure in live data. Then look at the fluid: if it is black, smells burnt or carries metal, the chain or pulleys are already damaged and a valve body alone will not save the unit. On this transmission, one quick check can save the purchase: all of the speed sensor plugs are the same style, and if the primary and secondary connectors were swapped during earlier work, the TCM will set pressure solenoid and ratio codes on a good valve body. Our CVT limp mode diagnosis guide lays out the codes-first approach, and the Jatco CVT problems and fixes guide explains when the damage has gone past the controls.
This assembly is listed for the JF017E in the 2016-2019 range. The JF017E sits only behind the 3.5L V6: Altima V6 and Pathfinder, Murano and Quest, and the Infiniti QX60. Four-cylinder Altimas and Rogues use the smaller JF016E, and that valve body will not interchange. Because the late-production units changed pressure sensors and calibrations, compare the casting shape, the harness connector and the sensor colors on your old valve body with the photos, or send us your year and VIN and we will confirm it before it ships. More 3.5L CVT parts are on our CVT parts page.
Low line pressure after a valve body swap often traces back to the oil pump, so if pressure stays weak, the JF017E pump for 2014-2020 is the next part to check. If your codes point to a single failed solenoid and the valve body bores are healthy, the 7-piece JF017E solenoid set is the lower-cost route. A unit that has already slipped hard may need a JF017E clutch drum as well.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
As pictured, it is a complete valve body with the solenoids, both pressure sensors and the internal harness installed. If you only want the loose solenoids, look at the 7-piece solenoid set instead.
No. Four-cylinder Altima and Rogue models use the JF016E, which has a different valve body. This assembly is for the JF017E behind the 3.5L V6.
Nissan NS-3 CVT fluid. Do not use a universal CVT fluid or a regular ATF, and check the level at the temperature given in the service manual.
Yes. Clear the codes and perform the TCM learning and pressure sensor procedures. Without them the transmission can engage harshly or set codes again even with a good valve body.
On the JF017E, swapped primary and secondary speed sensor plugs can set pressure and ratio codes. A worn oil pump that cannot make line pressure, or a damaged chain and pulleys, will also keep a new valve body from fixing the problem.
