There is a whole pack of Durango, Ram and Dakota owners who would dispute that.
As a Dodge tech I have seen zero failures in the field of the overdrive unit. I'd be more concerned with "904" related failures.
I'm amazed how many people tell me that "904 SUCK DUDE GET A 727" ignoring the legions of racers running them behind everything from 408 strokers to full blown Hemis without fail.
