I would be willing to bet a box of doughnuts that swapping the C6 for an AOD would get you from 13-16 to 16-19 mpg, unless you have a really tall rear end gear. The nice part is it is a bolt in, but looking at the numbers, is it worth it?
$3K for a trans swap, yes you can probably do it cheaper, but lets say you buy a nice, new AOD trans from somewhere and a few other pieces and widgets you end up with about $3K into the swap.
The AOD get's you 3 extra mpg on average. At $3 per gallon, it will take about 90,000 miles of driving to pay off the $3K spent on the swap, factor in inflation and net present value over the next 4.5 years that it takes for you to rack up 90K miles, and it probably isn't worth it.
But then again, NONE of the things we do to these old cars on this board are generally worth it from a pure accounting standpoint. It is just for the Fun, and it is arguably better than spending the cash on hookers and blow.
