Part of the motive power is converted to hydraulic power by hydraulic pump motors to obtain infinitely variable speed ratios. The transmission includes a hydraulic pressure control system that operates by the use of electrically controlled solenoid valves.

When the speed ratio is greater than the mode converting speed ratio, a second solenoid valve is operated to engage a second clutch. The engagement of the clutches is timed so that both clutches are not coincidentally disengaged.
