Hey Jeff,

I'm dealing with the same exact issue. Six and I have been corresponding about this issue just recently.

So your shifts are soft, that's good. No adjustment needed on the vac modulator

Shift points are primarily adjusted by the bowden cable nut (which I broke 2 days ago)

The accelerator cable nut (just above the bowden) tightens/loosen the cable. tightening it (iirc) will make shifts crisper.

However, my shifts from 2 to 3 still slip and shift around 4k at WOT (not good, esp on freeway). it doesnt flare and kick me into 3rd as it used to because i've softened it w/ the trans modulator (turning Ccw). I've read just about every trans shifting, bowden cable thread and i have read 2 or 3 guys say that their K2 valve springs were busted and by replacing it, the shifting returned to normal.
