The present invention relates to a hydraulic hybrid transmission including a control function of a hydraulic motor. The hydraulic hybrid transmission outputs power using the hydraulic motor when a vehicle drives at low speed. The hydraulic hybrid transmission enables the vehicle to drive at high speeds using a torque converter. The hydraulic hybrid transmission reduces fuel consumption and improves driving performance of the low speed. To achieve the purpose of the present invention, according to the present invention, the hydraulic hybrid transmission including the control function of the hydraulic motor includes: a hydraulic pump connected to a rotation shaft of an engine of the vehicle; the torque converter rotating as oil pressure is supplied from the hydraulic pump; a transmission clutch unit comprising a front clutch assembly and a rear clutch assembly as the power is transferred from an output shaft of the torque converter; a driving gear unit including a driving gear unit and the hydraulic motor, wherein the driving gear unit outputs the power transferred from the transmission clutch unit and the hydraulic motor rotates the driving gear unit by the oil pressure by being connected to the driving gear unit; and a control unit selectively controlling a motion of the hydraulic motor, the torque converter, and the hydraulic pump.
