But for this money must be paid so that even a small clutch slip under load such pads will lose their properties, charred from the friction. You will find that under load will "pop up" the transfer – and then simply will not be able to control the process, and at this stage "box" is simply necessary to "treat".

What will this repair – it depends on what exactly the problem. If the control unit suffered a hydraulic system, it needs to be changed. In the event that struck the spools, it's not so scary: they are replaced and the box was washed thoroughly. It should be noted that mechanical breakdowns Auto BMW's extremely rare, since the planetary gear and the torque converter boxes that have a large stock of strength. So that a mechanical problem diagnosis "automatic" bmw reveals extremely rare. Problem might be except that a number of planetary overdrive transmission – in the case where a driver over "reckless driver" on turns and high speeds. From the foregoing it is clear that the automatic transmission bmw are among the most reliable "machine".
Provided that the driver will faithfully comply with all recommendations of the manufacturer's manual machine and will not ignore the prescribed dates of service, you can spend on a trip without a single complication of thousands of 200 – 300 kilometers. Yes, and then repair "machine" will need to level, as already mentioned, the replacement clutch linings and preventive cleaning the hydraulic system, and then you expect the same trouble-free operation of automatic transmission for an additional 200 – 300 miles. And keep track of the symptoms of wear on clutch and adhesion (for a timely appeal to the service) is simple.
