Abstract
A power transmission has a compound input gearset, a Ravigneaux gearset, five friction type torque-transmitting mechanisms, and a one-way type torque-transmitting mechanism selectively engageable to provide at least six forward speed ratios and one reverse speed ratio for the transmission. The input gearset includes a planet carrier, which is stationary within a transmission housing and connected with a stationary portion of the transmission housing. The planet carrier also includes a central support member which provides nonrotatable housings for the apply pistons for three of the friction type torque-transmitting mechanisms.
