I would say GM has some of the best automatics out there, so much so that foreign competitors have been known to buy units for their vehicles. Much, if not all of the Mustangs fuel economy benefits come from the new (finally-efficient-enough-to-justify-DOHC) engine and other fuel-saving changes like the EPSA. Not the transmission.

I disagree. They had to use AFM or else be subject to the gas guzzler tax on the automatic V8's. There is no point in having AFM at all if they could do it without beating that tax.
