JF017E Overhaul Kit 2012, new and ready to install. Fits the JF017E. Ships fast from the USA.
This listing is for the rebuilder working on an early JF017E, the chain-drive CVT Nissan put behind the 3.5L V6 when the redesigned Altima and the unibody Pathfinder arrived. The kit pictured is a Transtec overhaul kit in its Freudenberg-NOK packaging, catalogued from 2012 for this unit. If your 3.5L Nissan CVT is leaking, takes a long pause before it engages Drive or Reverse when cold, or slips once internal leakage has dropped the pressure, a fresh set of seals and gaskets is the foundation of the fix.
Kit makers date their catalog coverage by the start of a transmission family, not by your model year, and the CVT8 family dates from that period. In North America, though, GEARS lists the JF017E starting with the 2013 Altima and Pathfinder. A 2012 model year Altima 3.5 or Murano runs the older JF010E (RE0F09) and needs different seals, such as the JF010E master rebuild kit. Go by the tag on the transmission case, not the year on the title of the vehicle.
Everything that makes a JF017E move is oil under pressure. The pump, controlled by its flow control valve, feeds the primary and secondary pulleys, which squeeze the drive chain hard enough to hold it without slipping. The select solenoid applies the forward clutch or the reverse brake, and the converter clutch is applied through its own circuit. On every one of those paths there is a seal: the gaskets on the pan, covers and housings, the lip seals on the clutch and brake pistons, the sealing rings that carry oil into the spinning shafts, and the O-rings on the valve body, solenoids and sensors. Heat cycles harden them, and pressure that should hold a pulley or apply a clutch leaks back to the pan. The overhaul kit replaces those soft parts. Clutch plates, a filter, the chain and the pulleys are not part of it.
Sonnax ties pump flow control valve wear to delayed engagement and low pump output on this family, and lists its main pressure regulator kit for low baseline pressure and slip, so a tired valve body can produce the same complaints as worn seals. Read the primary and secondary pressure sensors in live data and make sure the three identical speed sensor plugs are on the right sensors before blaming the hard parts. Drop the pan and look at the magnet: a light paste is wear you can rebuild through, while glitter and chunks mean the chain and pulleys need attention. The CVT slipping under load guide and the CVT failure patterns guide walk through that decision.
The JF017E (Nissan RE0F10E) was used only behind the 3.5L. On the early units this kit covers, that means the 2013 and 2014 Altima 3.5 and Pathfinder and the 2014 Infiniti QX60. Later units from 2015, which added the Murano and Quest, are cataloged under a newer kit, our JF017E overhaul kit for 2015-up. Gasket shapes and seal sizes can change within a run, so lay the old pieces next to the new ones before you start, or send us your year and VIN and we will confirm the match. The full lineup for these transmissions is on our CVT parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Probably not. GEARS lists the JF017E from the 2013 Altima on; the 2012 Altima 3.5 used the earlier JF010E (RE0F09) CVT. Check the tag on your transmission case, and if it reads RE0F09 or JF010E, use a JF010E kit instead.
The 3.5L V6 versions of the 2013-14 Nissan Altima and Pathfinder and the 2014 Infiniti QX60. For 2015 and later units, including the Murano and Quest, use the 2015-up kit.
The overhaul kit is the gaskets, piston seals, sealing rings and O-rings. A master kit adds friction and steel plates and usually a filter. Neither includes the chain or pulleys.
No. Whine that rises with road speed, especially with metal in the pan, usually points to chain, pulley or bearing wear. Seals fix leaks and pressure loss, so pair this kit with the hard parts your teardown shows are worn.
Nissan NS-3 CVT fluid. Check the level with the unit at operating temperature using a scan tool that reads fluid temperature.
