What I pictured was his mityvac connection to the tranny being directly to the line down to it. Proper TS procedure would be taking a reading at the line exiting the vcv before moving on to the hard plastic line to AT. I would start by correctly adjusting the vcv before pronouncing its demise. It could be that the linkage is set to where it is actually leaking out and never passing any vacuum. Then check the hard plastic vac line dropping down to side of tranny. Pull vac on it to see if it holds. Be prepared to replace rubber fitting at modulator, you'll understand when you get there. Think constant bombardment from anything escaping the engine bay and also anyything kicked up from the road along with the usual suspects, heat and age and whatnot.

NCKMSN - Did you at least read through the first link above. If this clicks the rest is icing.
