LS-9 transmission ?
 

Which one can you use?

a 6l90e will work. my father in law ran one for a while in his chevy II, but it was huge and you have to run low numeric gear ratio because of the gearing in the tranny. a 3.89 was too much imo. ended up taking it out and going t56 magnum. so much more enjoyable!!

Thanks for the info.

What did u end up going with. I have a ls9 and want to run an automatic

So ur ls3 with the charger. Has more power than a ls9. I have a 1969 camaro

I'm running a T-56 modified by D&D Performance and it has work great.

My LS9 in now 427 CID and makes 830 ft*lbs.

yeah, but you baby your stuff. :lol:

Anyone try Rockland Standard Gear's Tranzilla? They claim it will take 1,200 hp and 1,000 ft/lbs.

My new engine should hit 900 ft*lbs. I'm using a TR6060 this time.

D&D Perf built it and I'm sure it will work great.
