A multiple speed ratio manually controlled transmission mounted transversely with respect to the fore and aft axis of the automotive vehicle in which it operates includes a power input shaft having four forward drive gears and a reverse drive gear formed integrally therewith. A fourth speed ratio gear of the input shaft is continuously engaged with a fourth speed pinion journalled on a countershaft and a fifth speed pinion journalled on an auxiliary countershaft. The first, second and third forward speed gears of the input shaft are continuously engaged with corresponding pinions journalled on the countershaft. A first final drive gear fixed to the countershaft and a second final drive gear fixed to the auxiliary countershaft are each continuously engaged with a final drive gear that transmits power to the differential.
