A three-speed gearbox assembly for an electric drive vehicle includes four planetary gear sets connected to an electric motor output. A first clutch is configured to selectively couple the motor output to the first planetary gear set. A second clutch is configured to selectively ground a first portion of the first planetary gear set and a portion of the second planetary gear set to a housing. A selectable one-way clutch (SOWC) is configured to selectively ground a second portion of the first planetary gear set. The gearbox assembly is selectively switchable between (i) a first gear where the SOWC is engaged and the first and second clutches are disengaged, (ii) a second gear where the second clutch is engaged and the first clutch and the SOWC are disengaged, and (iii) a third gear where the first clutch is engaged and the second clutch and the SOWC are disengaged.
