LS-9 transmission ?

[turboapex]

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!!

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.
