ABSTRACT:
A throttle pressure adjustment valve is fluidly inteposed between a throttle valve and the shift valves and arranged to boost the level of throttle pressure under low engine load to a predetermined level. While the governor pressure is either very low or non- existent the elevated throttle pressure suitably modifies the shift charactertics of the transmission and obviates the generation of backlash noise and shifting in rapid succession under such conditions.
