JF017E Pump, new and ready to install. Fits the JF017E. Ships fast from the USA.
A JF017E with a tired oil pump sets up a slow chain of damage: engagement into Drive gets lazy when the fluid is hot, then the chain begins to slip on the pulleys under load, and eventually the pulley faces are scored. This new JF017E pump is for the rebuilder or shop that has found the pump to be the weak link in a 3.5L Nissan Altima, Pathfinder, Murano, Quest or Infiniti QX60 and wants to fix it before it takes the pulleys with it.
The JF017E is the chain-drive Jatco CVT built for the 3.5L V6. Its pump is driven by the engine through the torque converter hub, so it only produces flow while the engine runs. Everything downstream depends on that flow. The line pressure solenoid and pressure regulator valve shape pump output into line pressure; the primary and secondary reducing valves then turn line pressure into the clamping force that grips the chain; the select solenoid feeds the forward clutch and reverse brake. In a conventional automatic, low pump output means soft shifts. In a CVT it means the chain cannot be held, and that is expensive.
Inside the pump body sits a flow control valve. GEARS Magazine singles it out as a part that wears and sticks on Jatco CVTs, and Sonnax lists replacement and oversized versions of that valve for the JF017E because the bore wears from constant valve movement and lets pressure bleed back to the suction side.
Low pressure can also come from a worn valve body or a weak pressure solenoid, so rule those out. GEARS gives a 5.5 to 8.5 ohm range for the JF017E linear solenoids; check yours. Compare commanded and actual pressure with a scan tool, and use our CVT harsh or delayed shifts walkthrough for a step-by-step order. If the unit is out, vacuum test the flow control valve bore. A pump body that will not hold vacuum at that bore, or gears with visible scoring, is the case for a new pump. A judder that only shows up at light throttle is more often a pulley or calibration issue; Nissan bulletin NTB15-014C covers that separately.
This pump is listed for the JF017E transmission without a year limit. GEARS places the JF017E in the 2013-2018 Altima and Pathfinder, 2015-2018 Murano and Quest and 2014-2018 QX60, all with the 3.5L. Jatco revised the unit during its run, and pump assemblies were not always carried over between revisions, so compare the pump in your hand against this one before installing: bolt pattern, gear set and valve layout should match. Send us your year and VIN if you want us to check. If your vehicle is a 2014 or later build, also compare the JF017E pump for 2014-2020, and see the full range on the CVT parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if low pump output is the cause. Light-throttle judder on 3.5L models is often a calibration or pulley issue covered by Nissan bulletin NTB15-014C, so scan and pressure test first.
No. The pump sits behind the torque converter, so the transmission has to come out and the converter has to come off first.
Compare the bolt pattern, gears and valve layout of your old pump against this one, or send us your year and VIN. Builds from 2014 on should also be compared with our 2014-2020 pump.
A new front seal and pump O-rings at minimum, plus the filter and pan gasket. Inspect the chain and pulleys while the unit is apart.
Nissan NS-3 CVT fluid. Do not use a universal CVT fluid in this unit, and reset the fluid degradation counter after the service.
