Jatco JF010E

Transmission general data

The constantly variable transmission (CVT) RE0F09A/B (also named as JF010E – according to Jatco classification) is designed on the basis of famous RE0F06A, but for higher torque of Nissan engine with capacity equal to 3.5 liters V6 and since 2002 it has been used on Nissan Murano, and later (2007) modification for rare Maxima, Pressage, and for some time past installed on Teana of the Russian assembly.

Technical issues and repair guidelines

The delicate usage with a long oil heat-up and frequent oil change (NS-2) accompanied by the torque converter repair is the best way for a car owner to preserve CVT during the first years of operation.

Typical problems of “old” CVTs RE0F09A:

In general, this CVT family is one of the most reliable in the world and these transmissions have been a standard in the world of transmission manufacturers for a long period of time. But this CVT lost competition on the market of 3-4 liter cars to automatic gearboxes and even to DSG. The typical overhaul of this CVT requires the torque converter repair. Common problems of “old” CVTs are related to the pressure control valve (of the pump) wedging caused by overheating and contamination in summer time. The valve can wedge and switch-on after a heat-up, that leads to the dynamic load on transmission components and rapidly damages the belt and cones.

The long-term operation with contaminated oil wears out valves and plungers of the valve body. The most popular spare part for JF010E is a driving belt. The first reason of rapid belt wear-out is related to insufficiently warmed up transmission in winter time. The second reason of the belt damage is the driving at low speeds in traffic jams with harsh accelerations. The most common reason of damage for surfaces of the belt and shafts is related to the oil cleanness.

- Forward Clutch is exposed to burning in most cases. It is also common to replace Reverse clutches.

- Sometimes orders for repair include the step-motor which has quite limited operational life in overheated oil ( as in JF011).

The main factor for operational durability of this transmission is related to the state of shafts (input and output) which are unique in terms of design. The surface of cones is the main resource of this transmission. All other units of this gearbox are much cheaper or easily operate during two service lives of this CVT.
