I am wondering if a 6r80 transmission can fit into our bird since there is now controllers to run this transmission? I think that the first gear and a better spread would work great for a 4.6 2 valve. The big question is it too large to fit into the transmission tunnel?

BTW I am taking my Thunderbird to have the trunk floor modified to add a 16 gallon fuel cell.

That's a beefy looking trans.
