ABSTRACT:
A power transmission, for a vehicle, provides seven forward speeds and a reverse speed. The transmission has three planetary gearsets and has one sun gear member, which is held stationary for six of forward speeds and the reverse speed. The sun gear member is connected through a shaft to a torque-transmitting mechanism, which is disposed forward of an oil distribution snout and rearward of the vehicle engine.
