ABSTRACT:
A control system for a shiftable multi-speed hydraulically operated transmission system. The transmission includes internal clutches which are selectively operated by the control system to effect shifting in neutral, reverse or forward speed ranges. The transmission system includes a manually operable multi-position speed range selector switch, sensing devices for ascertaining transmission input and output speeds, and other condition responsive switches. The control system includes logic circuits therein for receiving input signal information from the switches and sensing devices and for providing output signals to effect automatic shifting of the transmission to a selected speed range. The electronic controller provides operational safeguards, responds appropriately to system failures, and displays of relevant system information.
