Have my cake and eat it too..

You want a built in cellphone with the controls on the steering wheel too?
I hear they have cars like that. :D

Seriously though, a good trans guy could do that with the 904 by simply how it is built.
I don't have a 904 but the same basic design with OD, and at light throttle you can hardly feel the shifts at all but they get much more defined with more throttle.
I mean bark tires on shifts just using more throttle opening, but soft as can be under light throttle.
It's a Transgo Stage 2 kit in a 42RH (A500).
