On that style of VB, since the throttle pressure is fixed(and high), the shift itself is basically the same under most conditions.

The difference in the shift feel is that when the converter isn’t locked up, the clunky shift feel is just absorbed in the converter slip.

The tighter the converter is, the smaller the window is to find a sweet spot to get the shifts in before the converter starts to lock up.
