A three-speed gearbox assembly for an electric drive vehicle includes three planetary gear sets. A first clutch selectively couples the electric motor output to a second portion of the first planetary gear set, a second clutch selectively grounds the second portion of the first planetary gear set, and a third clutch selectively grounds a portion of the third planetary gear set. A fourth clutch is selectively engaged to lock first and second axle shafts to provide a locked differential function. The gearbox assembly is selectively switchable between (i) a first gear where the second and third clutches are engaged and the first and fourth clutches are disengaged, (ii) a second gear where first and third clutches are engaged and the second and fourth clutches are disengaged, and (iii) a third gear where second and fourth clutches are engaged and the first and third clutches are disengaged.
