I had another look and noticed off the manifold pressure sensor there is the top line that goes to the brake booster and underneath there is a small vac fitting as well.
I am going to run off this lower fitting and see how it goes, worst comes to worst my trans will be shifting hard as anything with full line pressure if I dont get manifold vacuum to it.
