Done the facts and figures myself last year,and decided no way!! The AOD is only beneficial if you're running 3.8's or lower diff ratios. If you're running 2.7's or even 3's then fuel economy should be decent enough.Even if you ran 4.11's and drove highway all the time I reckon it would be a few years before it pays itself off. From a performance point of view (again with 3.8's or lower) I'd offer a cautious maybe because of the better 1st and 2nd ratios of the AOD,that's of course if you have a bottomless pocket. Almost forgot $700 for a used EB Falcon auto from the wreckers,don't forget they're over 10 years old,approx $150 to get the drive shaft shortened, almost $100 to adapt the old speedo cable to the electronic output and don't forget the farting around with the linkages.The only good news it bolts straight up without the need for an adaptor plate.Still want an AOD?
