Pairs the 30-tooth primary and secondary pulley set and steel belt with a full master rebuild kit for the Jatco JF011E / RE0F10A CVT.
When a JF011E CVT has slipped long enough to polish the pulley faces, a belt-and-seals job will not hold. This package is for that case: the 30-tooth primary and secondary pulley set with its steel push belt, plus a master rebuild kit of frictions, steels, seals, gaskets and O-rings, so the hard parts that wear together get replaced together. It is aimed at the 2007-2011 Nissan Altima, Sentra and X-Trail, the 2008-2011 Rogue, the Dodge Caliber, the Jeep Compass and Patriot, the Mitsubishi Outlander and the 2010-2011 Suzuki Kizashi, where owners are chasing a whine that climbs with road speed, a takeoff judder, or rpm flare under throttle.
The JF011E has no gear sets for the drive ratio. A primary pulley on the input side and a secondary pulley on the output side are each made of two cone halves, and hydraulic pressure squeezes those cones to move the steel push belt up or down the faces. The secondary pulley also carries a large internal spring that keeps clamp force on the belt. Torque only passes if the belt grips the cone faces, so once those faces are scored or stepped, a new belt rides on damaged steel and slips again. The master kit side of this package reseals every piston and renews the forward clutch and reverse brake packs, which is what restores the pressure that does the clamping.
Start with the pan. A Sonnax technical article in Transmission Digest traces the common JF011E whine to pitted pulley bearing races that flake steel onto the magnet, and that repair already means pulling the unit and splitting the rear cover. Once the pulleys are out, look at both cone faces under good light. A clean, even contact band means a belt-only or soft-parts rebuild such as our JF011E master rebuild kit with filter may be enough. Hard lines, a stepped edge or a glazed band means the cones are done and this set is the repair. If the unit has not come apart yet, our JATCO CVT problems and fixes guide and the CVT slipping under load guide help separate a pressure problem from mechanical wear.
The listing covers 2007-2011 Altima, Sentra, X-Trail, Maxima, Compass, Patriot, Caliber, Galant and Outlander, 2008-2011 Rogue, 2011 RVR and 2010-2011 Kizashi. Be careful with the V6 entries. The JF011E is the four-cylinder CVT; the 3.5L Altima and Maxima use the larger JF010E, and the V6 Galant and Outlander were built with stepped automatics, so confirm your case tag reads JF011E or RE0F10A before ordering. Jatco also built this pulley in more than one tooth count, and this set is the 30-tooth version. Count the teeth on the pulley you remove, or send us your year and VIN and we will check it. Every other part for this unit is in our CVT parts collection.
This is a bench job that needs a press, bearing drivers and a spring compressor for the secondary pulley. Before lifting the belt out, wrap two zip ties around it so the elements stay stacked, and note the direction arrow; Transmission Digest warns that a belt installed backward damages itself and both pulleys. When the valve body comes off, pin the pulley-ratio lever with a 3 mm rod through the access hole beside the filter bracket, and keep the original ROM chip on the internal harness, because it is calibrated to that car's TCM. Soak the new frictions, set clutch clearances as you stack the packs, and flush the cooler and lines. Fill with NS-2 on Nissan models, CVTF+4 on Dodge and Jeep, or the CVT fluid the Mitsubishi or Suzuki manual names. After installation, initialize the CVT and reset belt-slip learned data with a scan tool. If the valve body bores are worn, add our JF011E valve body solenoid kit rather than reusing tired pressure control.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Inspect both pulley cone faces once the unit is apart. If they show an even contact band with no scoring, a soft-parts kit and belt can work. Scored, stepped or glazed faces will wear a new belt quickly, so replace the pulleys with it.
Most 3.5L Altima and Maxima models use the larger JF010E CVT, not the JF011E. Check the transmission case tag. If it does not read JF011E or RE0F10A, this kit is the wrong part.
Count the teeth on the pulley set you remove from the transmission. Jatco built more than one tooth count for this unit, and this package contains the 30-tooth set. If you are unsure, send us your year and VIN before you order.
Nissan models take NS-2 CVT fluid. Dodge Caliber and Jeep Compass and Patriot call for CVTF+4. Mitsubishi and Suzuki owners should use the CVT fluid listed in their owner manual. Never use Dexron or a universal ATF.
Yes. After the rebuilt unit is installed, the CVT has to be initialized and the belt-slip learned data reset with a scan tool. Keep the original ROM chip on the internal harness, because swapping it in a Dodge Caliber sets a calibration mismatch code.
