Abstract
A system for controlling a a transmission (20) of a vehicle includes a sensor (30, 32) for sensing the speed of the engine, a controller (33, 37) connected to the sensor for controlling the output of the transmission dependent upon engine speed, and a threshold circuit (REF) connected to the controller for inhibiting transmission output until the engine speed has attained a predetermined level, above that normally required to drive auxiliary functions of the vehicle. In the system shown, the output of amplifier (33) is fed via reversing switch (37) to a valve (38) controlling displacement of pump (21). <IMAGE>
