The speed retarder control system includes a plurality of solenoid valves and reducing valves so arranged to receive pressure influenced hydraulic fluid and release the hydraulic fluid to a hydraulic fluid responsive vehicle retarder at a substantially lower pressure. The fluid pressure experienced by the retarder can be incrementially varied to result in varying degrees of vehicle retardation.
