JF015E / RE0F11A CVT master rebuild kit with a 29-tooth drive and driven pulley set, steel belt, frictions, seals and both filters.
This is the overhaul kit for the 29-tooth JF015E. It is aimed at the rebuilder who has a Nissan or Mitsubishi CVT on the bench with a marked belt or scored sheaves and wants every hard and soft part in one order. Inside is a remanufactured drive and driven pulley set with its steel push belt, a master kit of frictions, steels, gaskets and seals, plus both the internal filter and the external cooler filter. If you have been searching for a fix for RPM flare, shudder from a stop, limp mode or a P17F0 or P0746 that keeps coming back on a Versa, Sentra, Note, Juke or Mirage, start by confirming your tooth count.
The JF015E (Nissan RE0F11A) was built with two primary pulley designs. The 29-tooth and 30-tooth sets look close but do not interchange, and the wrong one will not assemble into a working transmission. This kit is the 29-tooth version only. Pull the unit, count the teeth on the primary pulley and match it before ordering. If you count 30, we list the 30-tooth master kit separately.
The primary pulley is driven by the engine through the torque converter and the secondary pulley drives the sub-gearbox and final drive. Oil pressure from the valve body moves one sheave of each pulley in or out, changing the diameter the belt rides on. Gears Magazine notes pulley pressure on this unit can reach 850 PSI, so a belt that has slipped once tends to keep slipping as the sheave faces glaze. The ATRA bench notes also flag wear points that are invisible from outside: the balls and rollers inside the pulleys, a primary piston that loosens and leaks, and a secondary speed sensor reluctor that walks off its press fit. A remanufactured pair addresses all of them.
Not every flare is a belt. Gears Magazine lists the pump flow control valve as the most common Jatco CVT failure, and worn valve body bores produce the same pressure codes. If the belt and sheaves are clean, a JF015E valve body with filter kit may solve it. Our CVT failure patterns guide and Jatco CVT problems guide lay out the order to check things in.
Reference numbers: JF015E, RE0F11A, 901068 and 33710S-1. The JF015E family covers small Nissan models including the Versa, Versa Note, Sentra, Juke and Cube, and the Mitsubishi Mirage, but the 29-tooth or 30-tooth pulley design is what decides fitment for this kit, not the badge on the car. Confirm the tooth count, or send us your year and VIN and we will help you match it. Browse every JF015E part on the CVT transmission parts page.
Clean the case and every valve body bore thoroughly, since debris from the old belt hides there. Fit the new frictions and seals, install the pulley set and belt together as one assembly, and replace both the internal and external filters. Inspect the pump flow valve and bearings while the unit is open; a JF015E oil pump assembly is worth adding if the bore is worn. Fill with Nissan NS-3 CVT fluid, check the level hot and run the CVT learning procedure with a scan tool, finishing with the Clutch Point Relearn. Professional installation is recommended. Note the shipping weight is about 35.9 lb because of the pulley set.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This is the 29-tooth kit and the two pulley designs do not interchange. Count the teeth on your primary pulley first; the 30-tooth master kit is listed separately.
The drive and driven pulley set in this kit is remanufactured and comes with the steel push belt.
Both the internal filter and the external cooler filter are included, along with the frictions, steels, gaskets and seals.
Nissan NS-3 CVT fluid. Set the level hot, then run the scan tool resets and the Clutch Point Relearn so the TCM learns the new pulleys and clutches.
Maybe not. A worn pump flow control valve or valve body bores cause similar flare and pressure codes. Inspect those first; if the belt and sheaves are clean, a valve body or pump may be the real fix.
