What would it take to put a g8 auto in a 04 GTO got the itch to try something different. I have access to a wrecked G8GT what would it take to convert my 04 auto GTO to a 6 speed auto?

Oh where to start..... First of all gut the interior so you can make the Trans tunnel bigger. The 6 Spd auto is huge. Then use everything from the G8. EVERYTHING... And then the headache will begin. Trust me I did it already.. How much for the G8?

Intake, Exhaust, Headers, 243 heads, a cam and you will be well over 400whp.
That 6 speed swap is going to be difficult from a software standpoint. You would need to swap to a 58x reluctor wheel engine and computer to be able to talk to the trans. It is not compatible with 24x ECMs.
