Abstract
A vehicle transmission system having shift lever control of synchronized couplers for selection of ranges of gears and electro-hydraulic powershift clutches for selection of a gear within the selected range is provided with controls for avoiding unexpected speeds or speed changes under certain conditions. On start-up, if the vehicle is stationary, a microprocessor automatically selects which powershift gear is effective, the selection being such that the start-up speed is as nearly uniform as possible within the limits imposed by the positions of the shift levers.
