Im looking to pull the t56 out of my 99 SRA cobra and go auto instead of building t56 only to go auto down the road anyways. First off I plan on going fmvb with a trans brake so It won't need to be automatically controlled, so what will I need to make the swap. Also I'm currently running 4.10 gears on a 100-150 shot and plan to go turbo in the near future. Doing some reading it's made to seem as though it'll be tough making a full 1/4 mile pass with 4.10s and staying out of o/d which you're not supposed to use under WOT. I am planning on having freddy brown do the transmission. Sorry for any obvious or stupid questions, I'm new to the auto thing.
