The invention relates to a dual motor hydraulic hybrid transmission. The transmission comprises a power source, a hydraulic circuit including a pump drivingly engaged with the power source and two displacement units, a hydraulic accumulator assembly including high and low pressure accumulators, one or more control valves, and an output shaft drivingly engaged with the first hydraulic displacement unit. The displacement units are in fluid communication with the hydraulic pump. The accumulators are in fluid communication with the hydraulic circuit. The second hydraulic displacement unit is drivingly engaged with the output shaft. The control valves are configured to selectively fluidly connect the hydraulic pump to the first hydraulic displacement unit while fluidly disconnecting the hydraulic pump from the second hydraulic displacement unit; and, simultaneously, fluidly connect the hydraulic accumulator assembly to the second hydraulic displacement unit while fluidly disconnecting the hydraulic accumulator assembly from first hydraulic displacement unit.
