Do you (or anyone) know the effect of too much vacuum at the VCV and modulator?

My gauge shows >15” at idle, and the vcv works beautifully taking it to zero.

But it’s >15.

So I sort of see two situations here... one where there’s too much vac, and the other where I know the modulator is leaky (have a genuine cap on order, as changing the rubber fitting didn’t help and the modulator looks good...).

The issue is that I still have a clunk in the final downshift from 2-1 when coming to a stop. My reading is that this is a sign of vacuum issues to the transmission, but it’s not clear which issue it might be for me.
