Hey Jason, you are the man, an AOD on a 347, can i ask you how much you paid for it, and did you have to modify your driveshaft?...what is the 4th gear ratio number? with the 3.90 rear, what do you cruise at on the freeway in terms of rpms and speed? What is it like clunkin into that overdrive? Does it do it automatically or do you have to do something? one other question, do you have Fuel injection on your 347? thanks
