Replacement 901063 steel push belt for the JF010E (RE0F09A/RE0F09B) CVT in V6 Nissan Murano, Maxima and Altima. For a full pulley-side rebuild.
When a 3.5L Nissan Murano, Maxima or Altima flares RPM on acceleration or judders pulling away from a stop, and the teardown shows a scored or stretched belt, this is the part you need. It is the 901063 steel push belt for the Jatco JF010E CVT, Nissan code RE0F09A and RE0F09B. The unit is remanufactured and is meant for a pulley-side rebuild, not a quick in-car fix.
The JF010E has no fixed gears for forward ratios. Instead, a belt made of hundreds of thin steel elements stacked on nested steel bands runs between a primary pulley on the engine side and a secondary pulley on the output side. Hydraulic pressure moves the pulley halves closer or farther apart, the belt rides higher or lower on each, and the ratio changes smoothly. Unlike an ordinary rubber belt, this one pushes rather than pulls: the elements transmit torque by compressing against each other. That only works when the pulleys clamp hard enough. Sonnax links loss of secondary pulley pressure control on this transmission to chatter on acceleration, push belt slippage and even pulley fracture, which is why a slipping belt and a pressure problem often show up together.
A belt cannot be judged from outside the case, so rule out the cheaper causes first. Scan every module and check battery voltage, since GEARS Magazine documented a hot-takeoff power complaint on an RE0F09B that was not internal at all. Check fluid level and condition, and look at pressure readings if you have the equipment. Our guide to CVT slipping under load walks through the order. If the case is split and you find chipped element edges, broken or worn bands, or step wear on the pulley faces, the belt is done. Never reuse a belt that ran on damaged pulleys, and never fit a new one to scored faces either. The Jatco CVT problems and fixes guide explains why the two wear together.
This belt is listed for the JF010E (RE0F09A, RE0F09B) in V6 Nissan Murano, Maxima and Altima 3.5 models. It is not interchangeable with the belt in the four-cylinder JF011E, and the later JF017E that replaced the JF010E behind the 3.5L uses a different drive element. Confirm the transmission code on the case tag or in your service records before ordering, and if you are unsure, send us your year and VIN. Every CVT part we stock is on our CVT parts page.
A belt job is a good time to reseal the whole unit, so pair it with the JF010E master rebuild kit and the JF010E pan filter. If pressure loss caused the slip, address it with the RE0F09A valve body as well.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This unit is remanufactured. It is sold as a replacement push belt for a JF010E pulley-side rebuild.
No. Four-cylinder models use the JF011E, which takes a different belt. This 901063 belt is for the JF010E (RE0F09A or RE0F09B) behind the 3.5L V6.
Only if the pulley faces are clean and smooth. If they are scored or stepped, a new belt will wear quickly against them, so replace the pulleys in the same job.
Low clamping pressure is a major cause. Sonnax ties secondary pulley control valve wear on this unit to chatter, push belt slippage and pulley damage, so check the valve body when you replace a belt.
Yes. After refilling with Nissan NS-2 CVT fluid and setting the level at temperature, run the CVT learn procedure with a scan tool.
