Abstract

The subject of the invention provides a transmission protection system (1) for motor vehicles equipped with low range of ratios and high range of ratios comprising a device for shifting gears LRC (2) operating in 'H' letter array. The gear shifting device (2) is connected to an electro pneumatic valve EPV (20)acting axially on a gear selection shaft (5) so that it counteracts accidental positioning of the gear selection shaft (5) in position of the gears 1 2 within the low range of ratios orin position of the gears 5 6 within the high range of ratios.
