Abstract
A gearshift range preconditioning system includes a gearshift device which, when manually-operated to effect a gear-change, initiates a signal to an electronic logic circuit which is coupled to the vehicle to receive vehicle-operating characteristics such as speed and engine RPMs. The electronic logic circuit evaluates this change request and the received operating characteristics in relation to predetermined optimum operating characteristics associated with optimum neutral gear ranges. The electronic logic unit then generates a neutral gear signal which is transmitted to a solenoid-valve-controlled neutral gear cylinder to effect operation of the vehicle transmission into the neutral position best suited for the specific vehicle-operating characteristics. An auxiliary range cylinder can effect selection of active gear positions between a high and a low state to achieve a doubling of possible active gear positions.
