A vehicle powertrain includes an engine, transmission, differential mechanism, and a gearing mechanism to control speed relationships. The gearing mechanism includes a plurality of intermeshing gears, two of which are selectively interconnectible by a torque-transmitting mechanism. The gear mechanism is arranged to control the speed differential between two members of the differential mechanism and therefore to control the speed relationship between the output gears or side gears of the differential mechanism.
