Patent ID: 6910986

Claim:
A seven-speed transmission comprising: an input shaft; an output shaft; a planetary gear arrangement having first, second and third planetary gear sets, each planetary gear set having a ring gear member, sun gear member and planet carrier assembly member; said input shaft being continuously interconnected with said sun gear member of the second planetary gear set, said output shaft being continuously interconnected with said planet carrier assembly member of the third planetary gear set; a first interconnecting member continuously connecting said ring gear member of said first planetary gear set with said planet carrier assembly member of said third planetary gear set; a second interconnecting member continuously connecting said planet carrier assembly member of said first planetary gear set with said ring gear member of said second planetary gear set; a third interconnecting member continuously connecting said planet carrier assembly member of said second planetary gear set with said ring gear member of said third planetary gear set; a first brake selectively interconnecting a transmission housing with said planet carrier assembly member of the first planetary gear set; a second brake selectively interconnecting said transmission housing with said sun gear member of the first planetary gear set; a third brake selectively interconnecting said transmission housing with said sun gear member of the third planetary gear set; a first clutch selectively interconnecting said sun gear member of the first planetary gear set with said sun gear member of the second planetary gear set; a second clutch selectively interconnecting said planet carrier assembly member of the first planetary gear set with said sun gear member of the second planetary gear set; a third clutch selectively interconnecting said sun gear member of the second planetary gear set with said sun gear member of the third planetary gear set; and said first, second and third brakes, and first, second and third clutches being engaged in combinations of two to establish seven forward speed ratios and a reverse speed ratio between said input shaft and said output shaft.
