thanks for all kind words buddy, there is no way to mount or match or whatever old stock 3 or 4speed trannies on such a modern and different engine like 3.6 lfx ... i bought all engine and trans(6t70 6speed) complete pullout.Cyrus, congratulations. This is the first time I am reading your thread. Top work! I used to own a 1992 Ciera (loved that car), so it is nice to see someone trying to keep one alive with a heart transplant. My own personal bias would have been to see you install a supercharged 3.8L, but the 3.6 will do nicely for you.
Dumb question: did you install the 6-speed transmission as well, or did you keep the 4 speed from the Olds? (sorry if I may have missed it in your posts)
