Just a thought to save MPG... can the TOD be disengaged from the rear tires with some sort of mechanical disengagement device on the rear drive shaft? Or would the lack of torque to the rear wheels completely screw up the transmission system?

Probably, you'd have to completely change out the transmission, drive axles, rear differential, computer system, etc...

Just wondering, as the TOD is what makes our lovely cars so gas hungry
