The Hydrak is a clutchless system (a vacuum-operated clutch plus fluid coupling, not a separate transmission) that owners either treasure as a rare curiosity or dread. Detractors describe it as unnerving to drive and terrifying to park in reverse, with obsolete parts making failures expensive; defenders love the driving experience and warn against deleting it because so few survive.
