ABSTRACT:
A transmission system for a vehicle such as a farm tractor comprises a solenoid-operated reversible multispeed transmission (twelve speeds forward and four reverse); an electronic control circuit for operating solenoids in the transmission to effect shifting; and a single lever control device including a manually operable control lever movable from neutral to forward or reverse positions and between upshift and downshift directions when in each position to operate electric switches which are connected to the electronic control circuit to effect desired shifting of the transmission.
