Complete JF015E / RE0F11A CVT overhaul: drive and driven pulleys with a 30-tooth primary, steel belt, frictions, filter and seals for Nissan and Mitsubishi.
When a JF015E comes apart with a scored belt or chewed pulley faces, a soft-parts kit is not enough. This master rebuild kit is built for that job on the 30-tooth version of the Jatco JF015E (Nissan RE0F11A): it pairs a new drive and driven pulley set and steel push belt with the frictions, gaskets, seals and filter for a full overhaul. It is listed for the 2009-2014 Nissan Cube 1.8L, 2011-2017 Juke 1.6L Turbo, 2013-2019 Sentra 1.8L, 2012-2019 Versa sedan 1.6L, 2014-2019 Versa Note 1.6L and 2014-2021 Mitsubishi Mirage and Mirage G4 1.2L, the cars most often towed in with RPM flare, shudder and P17F0 or P0746.
In this CVT the pulleys and belt carry all of the engine torque. Gears Magazine reports pulley apply pressures as high as 850 PSI, and that load lands on the sheave faces and on the balls and rollers inside each pulley that let the sheave slide while keeping it from spinning on its shaft. Those internals wear even when the faces look clean. The same article describes the primary pulley piston working loose and going egg-shaped, which creates a crossleak, and the speed sensor reluctor on the secondary pulley coming loose. Replacing the pulley pair and belt together removes all of those wear points at once, while the friction and seal set renews the forward and reverse clutches and the sub-gearbox.
Check the pan magnet and the fluid first. Fine paste is normal on this unit; bright flakes or a burnt smell point to belt and sheave damage. Our guide to CVT slipping under load explains how to tell belt slip from a hydraulic pressure fault on a scan tool. Gears also reminds builders to pull the pump flow control valve and check its bore, since a worn flow valve causes the same pressure codes; if that is your only fault, a JF015E oil pump assembly is a far cheaper fix than pulleys.
Reference numbers for this kit are JF015E, RE0F11A, 901068 and 33710S-1. The Mitsubishi version of this unit is called F1CJB. The critical check is the primary pulley tooth count: this kit uses a 30-tooth primary and will not work with the 29-tooth design. Count the teeth on your old primary pulley before ordering. If you count 29, use the 29-tooth master kit instead. If you are unsure which version your car has, send us the year and VIN. All JF015E parts are on our CVT transmission parts page.
Install the pulley set and belt as a matched assembly and do not mix in an old belt. Inspect every bearing for pitting, clean the case and pull each valve from the valve body to clean and check for bore wear, since metal from the failure will be trapped there. A sticking valve body is a common reason a fresh rebuild still flares; the JF015E valve body with solenoids is a sensible add when bores are worn. Fit the new filter, flush or replace the cooler, fill with Nissan NS-3 CVT fluid and set the level hot. Finish with the scan tool resets, ending with the Clutch Point Relearn. Professional installation is recommended.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Count the teeth on the primary pulley in your unit. This kit is the 30-tooth version and does not interchange with the 29-tooth set. If you cannot inspect the pulley yet, send us the year and VIN.
Yes, it is listed for the 2014-2021 Mirage and Mirage G4 1.2L, which use this Jatco unit under the name F1CJB. The tooth count check still applies.
Inspect the oil pump flow control valve and the valve body bores. Many builders replace the valve body and clean or replace the cooler, because debris from a belt failure collects in both.
Fill with Nissan NS-3 CVT fluid and check the level hot. Afterward run the scan tool resets for your model and finish with the Clutch Point Relearn, which takes about 30 minutes.
It is a full transmission overhaul that requires removing the unit, bench work and scan tool relearns. Professional installation is recommended.
