Blower + Auto
I have a 4x2 '79 f100, 351C,C6,9".
I am looking at blowing the cleveland.
From my limited understanding of auto's they use the manifold vacuum to sense when to change gear.(there is a kick down as well)
If the manifold is under constant positive pressure I assume the auto won't function.
Is there a magic trick to having a blown "auto" auto or will I have to lock it up and shift manually?
Thanks
Mike
