    Unlock convertor at 0% throttle?

    Fellas. Quick question. Would it wear out my lockup clutch or have any ill effects if I set the convertor to unlock when I let of the throttle? Cruise mainly. It seems to be much less harsh on the decel with it unlocked. It coasts further and eliminates drivetrain slack noise and at lower speeds it slightly bucks when coasting down I notice it because I?m very critical but most people wouldn?t notice it. I tried it and the only concern is I let off at cruise, it unlocks and then locks back when I press the throttle. I was afraid the added lock unlock cycles would prematurely wear out my lockup clutch?
