JF017E Master Rebuild Kit, remanufactured and ready to install. Fits the JF017E. Ships fast from the USA.
When a 3.5L Nissan Altima or Pathfinder CVT whines, slips, flares RPM under load or leaves metal in the pan, the chain and pulleys are usually what wore out, and a kit of frictions and seals alone will not fix it. This JF017E master rebuild kit is built for that job. It ships with a complete 30-tooth pulley set with the drive chain, interchange number 901096, plus a set of clutch plates for the clutch packs, as pictured. It is an aftermarket kit for the Jatco JF017E, known at Nissan as the RE0F10E, and it is meant for a shop or experienced rebuilder with the unit already on the bench.
The JF017E is the heavy-duty CVT8, built for the 3.5L V6. Instead of the push belt used in smaller Jatco CVTs, it runs a steel chain between a primary pulley on the input side and a secondary pulley on the output side. Each pulley has a sliding sheave that hydraulic pressure squeezes against the chain. Moving one sheave in while the other moves out changes the ratio continuously. Clamping pressure has to stay high enough that the chain never slips; once it does, the chain polishes and scores the sheave faces, and the damage builds on itself. Ahead of the pulleys, the forward clutch and reverse brake, applied by the select solenoid circuit, pick the direction of travel. Their plates wear like those in any automatic, which is why they come in this kit.
Pull a fluid sample and drop the pan. Fine metal on the magnet with a whine that tracks road speed points at the chain, pulleys or their bearings. Scan the TCM for ratio and pressure sensor codes, and check that the primary, input and secondary speed sensor plugs are on the right sensors; GEARS points out the connectors are identical and swapping them sets codes that look like a mechanical failure. If the noise and slip are real, the unit has to come out. Our CVT slipping under load guide and the CVT failure patterns guide help you decide between a rebuild and a replacement unit.
The kit is listed under JF017E, RE0F10E and 901096 for the 2012-14 Nissan Altima 3.5, the 2013-14 Pathfinder 3.5 and the 2014 Murano, along with export models such as the Teana and Elgrand and the Renault Latitude. It is a 30-tooth set, and pulley and chain parts were revised within the JF017E run, so count the teeth on your old pulley, compare the parts side by side with the photos, and check the code on your transmission tag. You can also send us your year and VIN and we will check it. The four-cylinder JF016E is a different, smaller unit and this kit does not fit it.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A 30-tooth CVT pulley set with the drive chain (interchange 901096) and a set of clutch plates, as shown in the photos. Instructions are not included. Check the photos for any seals or gaskets you will also need.
No. Those use the smaller JF016E. This kit is for the 3.5L V6 JF017E (RE0F10E), such as the 2012-14 Altima 3.5 and 2013-14 Pathfinder.
Usually not. A slipping chain scores the pulley sheave faces, and a new chain on damaged sheaves will slip again. That is why this kit replaces the chain and pulleys together.
Low or unstable pulley clamping pressure from worn valve body bores is a common reason the chain slipped in the first place. Sonnax links worn pulley reducing valves in this family to pulley fracture and slipping, so new pulleys need correct pressure to last.
Fill with Nissan NS-3 CVT fluid, check the level at the specified temperature, then clear codes and run the CVT relearn with a scan tool that supports Nissan before the road test.
