FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to gearshift drives in mechanical stepped gearboxes. Proposed drive consists of pneumoelectric actuator. Pneumoelectric actuator comprises two three-position air cylinders for selection and shifting gears. Air cylinders are arranged as-crossed in one case and controlled by normally-closed electromagnetic air-operated valve. Cylinder rods are engaged with gearshift lever outside of working chambers. Lever top end is rigidly engaged with gearshift cylinder rod. Lever lower end is shaped to shank in sliding contact with one of gearbox rods.
