Abstract
A power-assisted transmission with a gear shift suppressing arrangement in which the transmission is controlled so that the gears can only be changed when the clutch is completely disengaged. An electrical sensor senses and measures the movement of the clutch. The sensor is connected to an electronic evaluating circuit which controls the selection and the engagement of the gears. The evaluating circuit causes the disengagement of an old gear and initiates a serch for a newly selected gear when the clutch is depressed approximately two-thirds (2/3) of its full stroke. When the full clutch stroke has been reached, the newly selected gear is completely engaged. If the clutch is reengaged before the engagement of the newly selected gear, the transmission is shifted to the neutral position.
