c4 vs. AOD

[Rev]

It's an add on over drive unit that repaces the stock Tail shaft unit. It is longer than stock, so drive shaft work has to be done. I think there's a recent article in Mustangs and Fords on this. It does give either an automatic (tail shaft speed) or a manual push button operated over drive. It's supposed to be hellaciously strong (up to 600 lb/ft). They are expensive, $2000 or more. I bet they have a web site. Anyone know? Check Gear Venders.
