ABSTRACT:
An improved electronic control system for a vehicle transmission system having a plurality of sequential gear ratios allows the vehicle operator to selectively engage either a normal sequential gear ratio progression or a gear ratio progression that skips or omits certain low gear ratios from the gear ratio shift sequence. The transmission control system includes a microprocessor driven electronic control circuit that governs the transmission operation by selectively actuating, from a plurality of hydraulic clutch solenoid valves, a unique combination of solenoid valves for each gear ratio. Manually operable control means allows the vehicle operator to cause the microprocessor to select a software routine that omits certain solenoid valve combinations so as to progress through the transmission gear ratios during upshifts in the forward control mode at a faster rate, thus improving the acceleration of the vehicle in the low gear ratio range.
