In this case, it often concerns the electronics when something is wrong. As many probably know, the mechatronics consist of mechanics (the labyrinth) and electronics (the TCU). The maximum torque is limited, the mechanical parts wear and the control of the CVT (the mechatronics) sometimes fails. What becomes defective in most cases?Īlthough the 01J Multitronic seems like a wonderful solution, the system is not exactly faultless. Yet, to give the driver the feeling of driving a manual transmission, the system has 6 fixed positions programmed in its memory that are used once the “manual” mode is chosen. CVT stands for Continuously Variable Transmission, meaning that the system is stepless. Well… at least something that looks like changing gears manually. Next to automatic transmission driving, it enables manual transmission. In this case car owner should contact a service center as soon as possible.The O1J Multitronic is a typical modern CVT and uses mechatronics for its control (more about this later). If automatic gearbox breaks down, information about it will appear on the central panel of the car. The point is that the clutches are sold in sets only and require a complete replacement. A common problem is a breakdown of the clutch. This variator is extremely demanding to a lubricant mixture quality and oil pressure in the system. It leads to oil loss and insufficient pressure in a system. Sometimes problems can be caused by leaking oil seals and gaskets. You will need 7.5 liters of the original gear oil to carry out a complete oil change. It also should be noted that the key to trouble-free exploitation of this variator is a regular oil change using high quality spare parts. It can break down in summer heat and winter frost. This element doesn’t have a proper resistance to temperature changes. The weak point of 01J CVT is a control unit. This manual tells how to repair 01J CVT, if it’s broken down. Note, that this transmission gave a good account of itself: it is able to overcome more than 200,000 kilometers without overhaul.
