JF017E Overhaul Kit 2012-14, new and ready to install. Fits the JF017E. Ships fast from the USA.
This kit is aimed at the first production years of the JF017E, the chain-drive CVT that Nissan bolted behind the 3.5L V6. If you are tearing down a 2013 or 2014 Altima 3.5, a 2013 or 2014 Pathfinder, or a 2014 Infiniti QX60 because it leaks, hesitates before it grabs Drive or Reverse on a cold start, or slips once the mileage has worn the seals out, this is the gasket and seal set the rebuild is built around. The photo shows the kit sealed in a Precision International bag, and the listing labels it for 2012-14 units.
The JF017E is a close relative of the older JF011E, but it drops the stepper motor, adds an input speed sensor, and swaps the push belt for a steel chain to handle the torque of the V6. None of that changes the basic rule of a CVT: everything runs on oil pressure. The pump feeds the primary and secondary pulleys, and the pressure on their sliding halves is what clamps the chain so it can carry power without slipping. The same oil applies the forward clutch for Drive and the reverse brake for Reverse, and it locks the torque converter clutch on the highway.
Each of those circuits has to cross from a stationary part to a moving one, or from the valve body into the case, and every crossing has a seal. The overhaul kit supplies those soft parts: pan and cover gaskets, piston lip seals for the clutch and brake, sealing rings for the rotating shafts, and the O-rings at the valve body, solenoids and sensors. When those harden, pressure that should hold the pulleys or apply a clutch leaks back into the pan, and the computer cannot command its way around it.
Low pressure is not always a leak on this unit. Sonnax ties worn bores at the pump flow control valve and the main pressure regulator to delayed engagement, low baseline pressure and slip, so a tired valve body can look like a unit with bad seals. Start with a scan for stored codes and live pressure data, then check the fluid for metal. Glitter in the pan means the chain or pulleys are wearing, and seals alone will not save the transmission. GEARS also notes that the speed sensor connectors on the JF017E look identical, so make sure a previous repair did not swap them before you chase a ratio complaint. Our Jatco CVT problems and fixes guide walks through the common Nissan failures, and CVT harsh or delayed shifts covers engagement timing checks.
The listing covers the JF017E for 2012-14. Read that range as the kit maker's catalog window for early units rather than a model-year promise. In North America, GEARS lists the JF017E starting with the 2013 Altima and Pathfinder and the 2014 QX60, all with the 3.5L. A 2012 Altima 3.5 or Murano uses the earlier JF010E, which takes different seals, such as our JF010E master rebuild kit. Later 2015-up units, when the Murano and Quest joined the lineup, are better matched with our JF017E 2015-up overhaul kit. Confirm the Jatco tag on the case, and if you are not sure, send us your year and VIN before you order. You can browse every CVT part we carry on the CVT transmission page.
Check the label on the bag against your teardown so you know exactly which pieces are included, and keep the old gaskets until the new ones are matched up.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Probably not. In North America the JF017E starts with the 2013 Altima 3.5 and Pathfinder. A 2012 Altima 3.5 uses the JF010E CVT, which needs a different kit. Check the Jatco tag on the case or send us the VIN.
An overhaul kit is the gaskets and seals. A master rebuild kit adds frictions, steels and usually a filter. If the forward clutch or reverse brake packs are worn or burned, buy the master kit instead of reusing old plates.
No. Whine with metal usually means chain or pulley wear, or bearing damage. Seals restore pressure but cannot repair worn hard parts, so inspect the chain, pulleys and bearings before you commit to a reseal.
The JF017E takes Nissan NS-3 CVT fluid. Do not use a universal fluid or the older NS-2, and check the level at operating temperature.
Yes. After a teardown, clear codes and let the transmission complete its learning process with a scan tool that supports Nissan CVTs, then road test it gently until it has adapted.
