JF017E Overhaul Kit 2015, new and ready to install. Fits the JF017E. Ships fast from the USA.
If you have a 2015 or newer Nissan with the 3.5L V6 and its CVT is leaking, slow to pick up Drive on a cold morning, or slipping because internal pressure has bled away, this is the reseal kit for that unit. The box pictured is a TSS overhaul kit, number S82900E, labeled for the RE0F10E (JF017E) and 2015/up. That later-design label is the reason this listing exists separately from our earlier JF017E kits: it is catalogued for the second half of the production run, which is when the Murano and Quest joined the Altima, Pathfinder and Infiniti QX60 on this transmission.
The JF017E is the heavy-duty member of the Jatco CVT8 family, and it is hydraulic almost everywhere you look. A steel chain runs between a primary and a secondary pulley, and oil pressure clamps the sliding sheaves of both pulleys so the chain never slips. The select solenoid sends oil to the forward clutch and the reverse brake, the TCC circuit locks the converter, and a single pump with a flow control valve feeds all of it. Each of those paths depends on a seal: the pan and cover gaskets, the piston seals in the clutch and brake, the sealing rings on the rotating shafts, and the O-rings where the valve body and sensors meet the case. An overhaul kit is that soft-parts set. It does not include frictions, steels, a chain or pulleys, so it is the base you build a rebuild on, not the whole rebuild.
Low pressure on a JF017E is not always a leak. Sonnax lists low baseline pressure, belt or chain slip and delayed engagement as symptoms its oversized main pressure regulator and pump flow control valve parts are made to cure, so a worn valve body bore can look exactly like a unit leaking internally. GEARS also warns that the three speed sensor connectors on this unit are identical, and swapping the primary and secondary plugs sets pressure solenoid and ratio codes that can send you chasing the wrong problem. Check those plugs, read live pressure sensor data, and look at the fluid before the case comes apart. Our CVT harsh or delayed shifts walkthrough covers engagement timing, and the JATCO CVT problems and fixes guide sorts the common Nissan failures by cause.
This listing is for the JF017E, Nissan RE0F10E, with the kit labeled 2015/up. GEARS lists the JF017E behind the 3.5L only: Altima 2013-18, Pathfinder 2013-18, Murano 2015-18, Quest 2015-18 and Infiniti QX60 2014-18. For a 2015 or later vehicle in that list, this is the kit to start with. If your vehicle is a 2013 or 2014, look at the JF017E overhaul kit for 2012-14 instead, since kit makers split the run by year. The 2.5L four-cylinder models use the belt-drive JF016E and a different set of seals. Read the tag on your case before ordering, compare the old gaskets to the new ones on the bench, or send us your year and VIN and we will check it. Everything else for this family is on our CVT parts page.
Done this way, the kit restores the pressure every clutch and pulley in the JF017E needs, and it keeps a new chain, pulley or valve body from failing early on old seals.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 2015-18 Murano 3.5 uses the JF017E (RE0F10E), and this kit is labeled 2015/up for that unit, so it is the right starting point. Confirm the transmission tag reads RE0F10E or JF017E, or send us your VIN and we will check it before it ships.
No. An overhaul kit is the gaskets, piston seals, sealing rings and O-rings. Frictions, steels and the filter come in banner and master kits, and the chain and pulleys are sold separately, so add those if your teardown shows wear.
Not always. A pan or cover leak with no slip or delayed engagement can often be fixed with that one gasket. Buy the full overhaul kit when the unit is coming apart or when pressure loss is causing slip and slow engagement.
Nissan specifies NS-3 CVT fluid for this transmission. Do not use a universal multi-vehicle fluid, and check the level hot with a scan tool that reads fluid temperature.
A seal kit by itself does not change any electronics, but clear the stored codes and follow Nissan service information for any TCM learning steps your vehicle calls for, especially if the valve body or solenoids were replaced at the same time.
