Family of five-speed transmission mechanisms having a fixed stationary member

A multi-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 first, second and third members;
• said input shaft being continuously interconnected with a member of the third planetary gear set, said output shaft being continuously interconnected with another member of the third planetary gear set;
• a first interconnecting member continuously interconnecting said first member of said first planetary gear set with said first member of said second planetary gear set;
• a second interconnecting member continuously interconnecting said second member of said first planetary gear set with said second member of said second planetary gear set;
• a transmission housing continuously interconnected with said third member of said first planetary gear set;
• and
• four selectively engageable clutches for selectively interconnecting said members of said planetary gear sets in combinations of two to establish at least five forward speed ratios and one reverse speed ratio between said input shaft and said output shaft.
