Getting the modulator to hold vacuum is only the first step. Now that it does, you can tune the VCV. Don't give up the ghost now. Hopefully, additional vacuum to the modulator will soften the shifts.
Adjust the VCV so that it puts out 15-16" to the trans at idle. Then drive it and observe any differences.
If the modulator is working properly, the change in vacuum must affect the shifts.
