A transmission gearshifting arrangement in which the gearshift lever is provided with a normal shift position and a fast shift position, the latter resulting in relative motion between the gearshift lever and a cam plate. This relative motion produces closure of a fast shift switch to signal the electronic evaluation circuit of the desired fast shift. In the absence of a signal, a normal shift speed is indicated. A pressure control valve capable of producing a bilevel rate or pressure is controlled by the evaluation circuit to cause a power cylinder to effect the gearshifting at either a normal or a fast speed. |
