Pairs the 30-tooth pulley set and chain belt with a full master rebuild kit for the Jatco JF017E CVT in 2013-2014 Pathfinder, Murano and Altima 3.5L.
If your 3.5L Nissan Pathfinder, Altima or Murano has started to judder pulling away, flares RPM on a light-throttle climb, or came back from the shop with a verdict of scored pulleys, this is the box that puts the CVT back together in one order. It combines a matched 30-tooth pulley set and drive chain with a complete master rebuild kit of frictions, steels, seals and gaskets for the Jatco JF017E, the unit Nissan tags RE0F10E. It is built for the rebuilder who has already torn the unit down and found the hard parts are past saving, not for a fluid-and-filter service.
The JF017E is the heavy-duty member of the Jatco family that sits behind the VQ35 3.5L. Where the smaller JF016E uses a steel push belt, the JF017E runs a chain between a primary (input) pulley and a secondary (output) pulley. Each pulley is two cone halves; hydraulic pressure squeezes the halves together to change the working diameter and set the ratio, and that same clamping force is all that keeps the chain from slipping. The valve body meters it through separate primary and secondary pressure solenoids and two reducing valves. When that clamping falls short, even briefly, the chain skids across the cone faces and leaves a polished, stepped or scored track. Once the faces are marked, a new chain on old cones slips again almost immediately, which is why this kit replaces both together.
The rebuild kit side covers what any overhaul needs: the forward clutch and reverse brake frictions and steels that the select solenoid applies, plus the seals, O-rings and gaskets throughout the case, so the hydraulic circuits that clamp the new pulleys hold pressure.
Judder alone does not condemn the pulleys. Nissan's bulletin first calls for a TCM reprogram on affected builds, and Sonnax ties chatter and slippage to wear in the primary and secondary pulley reducing valve bores, so a worn valve body can cause the same complaint. Scan for codes, check the fluid condition and degradation counter, and read our CVT slipping under load guide for the test order. If the unit is already apart, inspect the cone faces under a light: any step you can catch with a fingernail means the pulleys go. If the cones are clean and only the frictions are worn, the standalone JF017E overhaul kit is the cheaper route.
The listing covers 2012-2014 Nissan Altima 3.5L, 2013-2014 Pathfinder 3.5L, 2014 Murano 2.5L and 3.5L, 2013-2014 Teana 2.5L and 3.5L, 2013-2014 Elgrand 3.5L, 2014 X-Trail 1.6L and 2012-2014 Renault Latitude 2.5L and 3.5L. Several of those are export models. In the US market GEARS Magazine places the JF017E in the Altima starting in 2013, so read the tag on your case and make sure it says JF017E or RE0F10E before ordering.
The bigger catch is tooth count. This pulley set was produced in 25, 27 and 30-tooth versions, and the VIN will not tell you which one your unit has. Count the teeth on the pulley you remove. This kit is the 30-tooth version only. Unsure? Send us the year, VIN and a photo of your tag, or browse every JF016E and JF017E part on the CVT parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Count the teeth on the pulley you remove from your transmission. The tooth count cannot be decoded from the VIN or chassis number, and this kit is the 30-tooth version only.
Not if the cone faces are scored or stepped. A new chain on damaged cones will slip again quickly, which is why this kit pairs the pulleys and chain as a set.
The listing includes it, but most US-market sources show the JF017E arriving in the Altima for 2013. Read the transmission tag; if it says JF017E or RE0F10E, it is the correct unit.
Inspect the valve body at the pulley reducing valve bores and the pump flow control valve. If either is worn, replace it now, or the new pulleys will not get the clamping pressure they need.
Use Nissan NS-3 CVT fluid only. After the unit is in, perform the CVT initialization and clear the belt and fluid degradation counters with a scan tool that supports Nissan CVT functions.
