A hydraulic transmission system includes the use of a geared cone 12 having geared rings 46-52 which mesh with respective clutches 30-36 of a drive shaft 16. The clutches 30-36 individually engage by use of hydraulic pressure directed by an input chamber 102. Engagement is accomplished when an internal parted disc 62 separates as a result of hydraulic fluid pressure and engages upon an, otherwise free-wheeling, internal surface of the clutch's external dish 60. When engagement occurs, work is transferred from the input shaft 18, through the gear cone 12, to the dish 60, through the engaged disc 62 and to the drive shaft 16.
