Ok so putting final touches on 56 chevy.....5.3 on3 7875 th400.
Question is can I just hook up vaccum line that goes to trans modulator as normal? I dont expect it to be able to shift under boost /full throttle but girlfriend does drive it and she just likes to put it in drive and go....( will probally never see positive pressure with her driving)
Or am I stuck showing her how to shift it like a manual valve body? Lol

TransGo makes a check valve for the modulator.

I have just hooked them up to a vac source and not had a problem. But your prob
better off using the Transgo style valve, just make sure its vertical.

So I hooked up the trans go t/valve last night it's just a simple ball and seat.....any way wont it have a boost leak with that set up?
Or is it not enough to matter?

Tiny leak. Nothing to worry about.
