Just an idea. Although I want to do it soo bad. Would the 6 speed auto they put in the 12-14 w impala bolt up to my 3800? I know that trans is only used with the 3.6 but I figured instead of going crazy and doing a manual swap this would be (slightly) more straightforward. I don't expect it to just drop in but I could run it off a standalone computer couldn't I? Interested to hear what you guys have to say..
