I have an 03 GT and would like to swap out the manual transmission for an automatic. I should have the 3650 tranny and would like to switch to a stock auto, i believe 03's had the 4r70w autos correct? Whats the difference between the 4r70w and the AODE? What parts would i need to make this conversion. talking stock to stock, this is my fiances daily driver and she is having a hard time learning to drive a stick.
