just wondering what the cost is and the PITA in changing out the PCM involved in going from 6 speed to an A4? thanks
Cheapest way to do it is to find another F-body willing to swap for little or no money. Interested in coming down to Houston? I've been considering switching to a stick (don't drag race this convertible much...it's too nice).
If you don't have a donor car, it can be quite expensive. Some others members can chime in.

I just completed this swap last month , I had someone wanting to go to a M6 so the money wasn't to bad , $450 to have my computer reprogrammed , $175 for the harness that goes to the tranny and a ton of man hours !!! Im very happy with my results , but to be honest I would NOT do it again !!! Just trade it in for a A4 !!!! If you decide to do it , I will help you any way I can !!!
