ABSTRACT:
A multiple speed ratio power transmission mechanism for an automotive vehicle adapted to be mounted in a transverse position with respect to the fore and aft axis of the vehicle includes a torque input shaft having input gearing fixed thereto. A first countershaft has gearing journalled thereon meshing with the torque input gear and synchronizer clutches adapted to produce a driving connection between the input shaft and the countershaft. A second countershaft has a fifth forward speed gear in meshing engagement with a gear on the input shaft and a synchronizer clutch to produce a driving connection between the input shaft and the second countershaft. A one-way clutch supported on the input shaft produces a one-way driving connection between that shaft and the gear wheel. Rotatably supported on the shaft is a gear that is in continuous meshing engagement with fourth and fifth speed pinions, each pinion carried on one of the countershafts.
