Abstract:
1. A vehicle transmission comprising: a stationary member; a differential gearset having first, second, third, fourth, and fifth coaxial gear elements operatively interconnected with one another; an input shaft being operatively connected to the first gear element; a first selectively engageable torque transmitting device mounted to the stationary member and operatively connected to the second gear element; a second selectively engageable torque transmitting device mounted to the stationary member and operatively connected to the third gear element; and an output shaft; wherein the differential gearset is configured such that the rotational speeds of two of the gear elements may be independently established and determine the rotational speeds of the other three gear elements; and wherein the fourth gear element is selectively operatively connectable to the output shaft at at least one speed ratio, and wherein the fifth gear element is selectively operatively connectable to the output shaft at two or more speed ratios.
