RANGE SHIFT CONTROL BY INPUT GOVERNOR Abstract of the Disclosure A multiratio powershift transmission having automatic shift valves normally operative in response to output speed governor pressure and throttle pressure to automatically upshift the transmission to higher ratios with increasing speed with the upshift at higher speeds with increasing throttle. A back-up governor pressure system having an input governor pressure regulated by a pressure regulator valve to provide a reduced modified governor pressure in first ratio and operative in response to progressively higher ratio signals to progressively increase the reduced pressure to provide a modified input governor pressure varying with output speed similar to output governor pressure which is used instead of output speed governor pressure to provide a similar shift schedule relative to output speed.
