Default Vacumn source
Those of you running T-400 trannys, where did you source the vacumn for the modulator?
TIA

You didn't volunteer what engine you have, but your vacuum source needs to come from the manifold after the TB or carb.

As stated manifold vacuum as long as not a turbo or super charged car or truck, In those situations special things need to be considered such as a one way check valve to avoid positive pressure to the modulator
