Ah yeah, I see what you mean Stav thanks. I was thinking of something like a C4 or a TH400 'box? So a fairly simple 'box in an old skool muslce car or whatever...

See what you mean about the change up point, it would vary due to infinite driving condtions/styles etc.

If you fit the manual valve body will it be totally manual? No kickdown etc, just the same as a manual 'box with no clutch? Could you still be gay whack it in drive and let it do it for you?
