A hydraulic transmission control circuit for modulating the controls of a loader includes an accumulator connected to the reverse speed clutch. The accumulator, which has a free sliding piston, has one end communicating with the reverse speed clutch, while the other end of the accumulator has an inlet communicating with the discharge port of a torque converter for charging the accumulator and an outlet communicating with a fluid reservoir through a check valve. A directional control valve may be utilized to selectively connect the accumulator with the reverse speed clutch or a forward speed clutch for respective loader or bulldozer applications.
