Ok so since my 284 swap was a fail and i have to convert the car back to Auto. I am thinking about a 4t80e swap. I have read through what is listed here on the thread. But am looking for more in detail help.

This will be bolted to an L32 in a 2004 grand prix. Car is daily driven so i want the trans to be controlled as factory if even possible. What axles do i need? Pretty sure ill need headers cut/rewelded for the bigger trans. Mounts i can fab. Is there going to need to be any body modifications done to fit the trans?

Trying to collect as much useful information as possible.
