i know its still a little early on the 6l80e/6l90e swaps, just wondering if the trans itself is similar in size to a 4l80e? i will be going with one of the two in the near future, although with the 4.03 first i will have to get rid of the 4.10s and get 2.73s!

What about Manumatic Capability??? This the same tranny that John Heinricy, the former director of GM Performance Division, did his historic sub 8 min run as the fastest production 4 door sedan on the Nürburgring.

Any change in opinion on the 6L90E?? It has been a few more since the intro of the 6L80E/6L90E and I was wondering it there anyone out there has more experience with this transmission and/or change in opinion as to using this tranny in big HP/TQ LSx applications as opposed to the tried and true 4L80E.
This tranny as certainly proven itself in the last couple of years. I read that when John Heinricy made his historic run sub 8 min run at the Nurburgring in 2009 the supercharged Caddy CTS-V he didn't even manually shift it he just put the gear selector in D and went for it.
