A multi-speed unit desirably always drives the output members at equal torque levels while imparting multi-speed capability thereto. The multi-speed unit is driven by the input member and drives the remaining third one of the elements of the second planetary set in at least one speed. The multi-speed unit preferably includes a third planetary set, one brake assembly and a clutch assembly, or two brake assemblies connected to pre- selected ones of the ring, sun, and/or carrier elements thereof.
