JF017E Pump 2014-2020, new and ready to install. Fits the JF017E. Ships fast from the USA.
This new oil pump is listed for 2014-2020 JF017E transmissions, the later run of the chain-drive CVT that Nissan fits behind the 3.5L V6 in the Pathfinder, Murano, Quest, Altima and Infiniti QX60. Owners usually land here after a shop pressure test comes back low, or after a teardown shows a scored pump body: the CVT is slow to pick up Drive on a hot day, flares under load on the highway, and the fluid is dark well before the counter says it should be.
Every pressure in the transmission starts at this pump. It is turned by the torque converter hub, and its output goes to the pressure regulator valve, where the line pressure solenoid sets the base pressure. From there the primary and secondary pulley reducing valves build the clamping pressure that holds the chain, the select solenoid feeds the forward clutch and reverse brake, and the TCC circuit controls lockup. On the 2014-and-later units these demands are higher on tow-rated Pathfinder and QX60 applications, which is why GEARS stresses that cooling and a healthy hydraulic supply matter so much on this heavy-duty CVT.
The wear item in the pump is the flow control valve and its bore. As the bore opens up, pump output leaks back to the inlet side, and the loss shows up first when the fluid is hot and thin. Sonnax sells standard and oversized valves for exactly this repair on the JF017E, but a pump body with gear scoring or a badly worn bore is a replacement job.
Start with the cheap checks: fluid level at temperature, fluid condition and the degradation counter. Then compare commanded against actual line pressure. If pressure is low at hot idle and improves with RPM, the pump or its flow control valve is a strong suspect. If pressure is fine but you have judder at light throttle, look at the TCM calibration and the pulleys first, as Nissan's bulletin NTB15-014C describes. Our CVT slipping under load guide lays out the test sequence, and the Jatco CVT problems and fixes guide covers the other common JF017E failures.
Listed for the JF017E, 2014-2020. That range lines up with the later Pathfinder, Murano, Quest, Altima 3.5L and QX60 builds. Jatco updated the transmission during that span, so match the pump you remove against this one (mounting bolts, gear set and valve arrangement) before installation, or send us your year and VIN to check. Earlier 2013 units should also be compared against the standard JF017E pump. All related parts are on the CVT parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2014-2020 units. A 2013 transmission may use the same pump, but compare your old pump against this one or send us your VIN before ordering.
Hot fluid is thinner, so a worn pump or flow control valve bore leaks more and output drops. That is a classic sign of pump wear, but confirm with a pressure test.
On a high-mileage or towing unit, yes. The transmission has to come out anyway, so inspect the pulleys, chain and valve body and plan an overhaul if they show wear.
Yes. Reset the fluid degradation counter, and check line pressure and the stored codes after the first drive.
No. Use Nissan NS-3 CVT fluid in the JF017E.
