A vehicle transmission particularly suitable for an agricultural tractor provides a large number of drive ranges by combining manual selection of any of several speed ranges while the vehicle is stopped with power shifting being available while the vehicle is in motion. The arrangement of the transmission allows the input shaft to be located at the top of the housing, with a plurality of shafts carrying the shift assemblies located immediately below the input shaft. The output shaft is positioned in the lower portion of the housing providing output torque at both ends of the housing, thereby eliminating the need for a transfer case normally required in interconnecting a transmission to both the front and rear wheels of the vehicle.
