Abstract: A remote control system for an automotive transmission in an earth-moving vehicle which includes a fluidic variable frequency oscillator having a variable feedback loop controlled by a quadrant lever which acts as a gear shift control. When the lever is moved between spaced transmission control positions, the frequency of the signal at the output is swept through the frequencies corresponding to intermediate control positions. The waveform of the output signal is non-symmetrical having a fixed "off" time and an "on" time which varies in length as an inverse function of the frequency. The output signal is fed to a fluidic transmitter, then through a pair of conduits to a fluidic receiver. The "on" output port of the receiver feeds into a manifold developing pressure therein which varies with the degree of dissymmetry of the wave, that is, inversely with frequency.
