THE OUTPUT OF THE PLANETARY GEAR SET IS THROUGH AN OUTPUT GEAR THAT IS LOCATED CONCENTRICALLY AROUND THE INPUT SHAFTS AND IS POSITIONED BETWEEN THE TORQUE CONVERTER AND THE PLANETARY GEAR SET. A PLURALITY OF FORWARD DRIVE GEAR RATIOS AND A REVERSE RATIO IS OBTAINED BY SELECTIVELY ENGAGING THE CLUTCH MEANS POSITIONED BETWEEN THE ENGINE AND THE TORQUE CONVERTER, AS WELL AS ADDITIONAL FRICTION ENGAGING DEVICES POSITIONED RADIALLY OUTWARDLY FROM THE PLANETARY GEAR SET.
