Trans suggestions for 2nd gen Ls3 Firebird ...

[cpd004]

I'd like opinions on running an auto trans behind my 2010 Corvette Ls3 in my 71 Firebird. I'd love to go 6L80e like I have in my G8 but I understand it requires some mods (although there is at least one person running one stating he didn't need to do any cutting).

The main purpose of this car is for Power Tour, car shows and all around reliable daily driving. I prefer a firmer shifting car and I'm currently running a 3.42 rear. The engine is stock other than a tune and headers.



Interested in opinions for a donor car. I already have a PSI harness (15 pin) and trans controller. Seems to be a bunch of options out there and have no idea where to start.
