Would it be of any use to try the varied levels of vacuum supplied to the modulator? I used ~ 14 mm Hg, but I could also try to make separate runs with 12.5, 13, and 13.5 to see if there's any sensitivity in shift quality to that level...
I think I don't want to adjust the modulator blindly - I'll have to rig up the gauge contraption described in the Wiki and get some numbers out of it.
I had my car at the Benz dealer this week, and they told me the tranny is leaking around the B1 band. Could that have any bearing on the internal tranny pressure and shift quality?
