How to build an automatic gearbox from Lego Technic on the basis of a differential. 
The box operates on an increased gear and when a load on the shaft appears, the box switches to a lower gear. The box works when the shaft rotates in both directions. It was not possible to apply the box for practical purposes because the switching mechanism based on the differential starts to break its gears  at high loads. 
The following videos were taken as the basis of the design:

Most likely this option from the video

will be practical, because in theory, the mechanism must withstand heavy loads.
