By definition, a transition can't operate on one frame. If that's what you really want, I think you'd need to use a key-framed volume control.
If you can live with a change over 2 frames or more, go into Trim mode ("t"), select all the clips, then move the transition into the clip "out" position with "U". Then Shift+t. If you're doing a lot of them, it would probably be easier to change the default transition to the number of desired frames, first.
