what transmission to use

[ADentice]

You can get a trans out of a 2000- 2006 2 wheel drive truck but lq4s usually use 4l80s. You would have to build a 4l60 to handle what you want, a stock 4l80 will last a lot longer without needing a rebuild

You could go with the transmission your car is supposed to have...a 200 4R. A lot of guys have used them behind LS motors and you already know the 200 4R is the factory transmission for a turbo Buick. They can be built relatively cheap, have a desirable gear ratio and will take the abuse. Check out these guys...very popular with the Grand National crowd with many solid reviews.

good links I just confirmed my car does have a 200 r4 but still thinking about going with a 4l80e

Do it, you wont regret it. It'll handle whatever you want to throw at it and thats what is usually behind an lq4. A stock 4l80 will have no problem handling 500hp long term
