 Full throttle downshifts were achieved by the throttle valve which permitted the transmission to stay in low range or be forced into downshifting to speeds between .At speeds under , heavy throttle would delay upshifts, or initiate a forced 'detent touch' kickdown for better performance.When Low Range or Reverse are selected, the apply pressures are not modulated and the full line pressure of the transmission is applied to ensure positive engagement.
