Abstract: The present invention provides an automatic transmission for a motor vehicle having a compact single mode transfer gear continuously variable transmission (CVT) with a compound planetary gear carrier for use in front wheel drive vehicles. The automatic transmission includes an input shaft, a variator or other, similar device which provides a continuously variable input to output speed ratio over a limited range, a compound planetary gear assembly having a sun gear, a planet gear carrier with compound gear sets and a ring gear, a friction brake, a friction clutch and a plurality of transfer gears and layshafts.
