About the work of CVT company Jatco, a lot of rumors. Someone got lucky with buying a car, and someone after a few tens of thousands forced to change the box under warranty. What affects the endurance of this node? What is actually the resource variable to "Nissan X Trail"?
Since 2007, the company Nissan has decided to equip the SUV "X-Trail" boxes variable speed type. Body T31 of the first generation were equipped with a CVT Jatco RE0F10A (aka CVT-7).
Its capacity is calculated on engine capacity from 1.6 to 2.5 L. These data provided by the dealerships. However, on the website of the company Jatco provided a little more volume from 1.6 to 1.8 L. If CVT-7 is designed for subcompact cars, it becomes clear why he is so hard to work out your life without a break.
Torque car reaches a maximum of 180 Nm, while the engines with a displacement of 2 l and more issue 200 Nm. The CVT can't cope with this load.
Aggressive driving creates a need for a rapid shift between gears, as well as in the design of the variator a lot of rubbing compounds, its wear is accelerated significantly. So a lot depends on how you uses the CVT to "Nissan X Trail" the car owner himself.
From working some of the elements of the CVT to "Nissan X Trail" T31 depends on its service life?
Most of the load when changing gears carry the bearings of the pulleys, the pulleys and belt transmit a rotation from the drive shaft to the slave. The caveat is that these pulleys are completely smooth, and the grip strap is only due to friction.

According to owner reviews, the CVT "Nissan X Trail" generation T31 makes itself felt after only 80 000-100 000 km, although the promised resource - 200 000.
First worn out bearings starting to emit a characteristic hum. Depends on the belt tension. If the bearing is not doing its function of the tensile force of the belt is reduced, it starts to slip, not allowing the shafts of signal transmission. In the first stage malfunction common box to "Nissan X Trail" "troit" (there are jerks). This is because the pulleys, turning idle, deformed, getting scuffs and scrapes.
There is on the hydraulic unit element for regulating the gear ratio is a step motor. He monitors the accelerator pedal position and travel mode. Information transfer is on the moving parts of the pulleys by foot step-motor, which is quite fragile and wear out quickly, which leads to the variator only on one speed.
Repair of a variator to "Nissan X Trail" T31 is problematic: if there are spare parts for replacement, their price will be unpleasantly high. The service can carry out Troubleshooting and an estimate. But if the warranty is still valid, experts recommend replacing the variator on "Nissan X-Trail."
Refine the type of variator to "Nissan X Trail" CVT-8 increased its resource and endurance to aggressive style of driving.
The Weight of the powertrain have reduced, made more compact oil pump. Reduced friction of the belt on the pulleys is 40%, thereby reducing the pressure on them. For fuel economy change in the transmission ratio made speed.
According to the owner reviews on the CVT to "Nissan X Trail" CVT-8, we can assume that it lasts longer. His resource is designed for 250 000 km of operation.
The CVT is fundamentally different from the box "automatic" or "robot". It has no gears, due to which the engine load is reduced.
How to use the CVT to "Nissan X Trail" and what's driving manners stick to the box last longer?
The owner Reviews on the CVT to "Nissan X-Trail", his features are that created this unit for a leisurely drive on smooth roads.
According to the regulations of the manufacturer maintenance of the variator should be done every 60,000 km operation. To be sure, motorists are trying to pass IT more often - after 40 000-50 000.
Change the oil in the variator to "Nissan X Trail" can spend like a HUNDRED, and himself.
To change the transmission fluid in the CVT, you must have:
Based on what CVT stands for "Nissan X Trail", is selected, and transmission fluid. Auto body T31 released oil, NS2, auto body T32 - NS3.
Oil NS3 designed for betraveling speed drives and operate at higher temperatures. It has a low viscosity and, according to developers, is suitable for CVT-8, and for the CVT-7. However, owner reviews on the CVT to "Nissan X Trail" with a box CVT-7 working on NS3, suggests that may appear extraneous noise due to the lack of lubricating oil layer.
To Start the procedure with the warming up of the engine and CVT box to "Nissan X Trail". Then:
A Feature of the CVT-8 that he does not have the factory dipstick. Check the level by filling the new oil, or to call the service station. There is a probe, which is inserted into the neck to fill.
To replace the oil you will need:
As in the case with the oil change on the CVT-7, the machine must be put on the lift or a viewing hole. In this case you will need a helper and diagnostic scanner. If there is no scanner, you can substitute a thermometer (necessarily digital) on the pallet.
To access the bottom, driving the car on a pit or hoist. Further:
A Complete replacement of the transmission fluid held. You can now reset the counter value.
