Vacuum modulator is brand new. It appears to be working because I adjusted the shift point last night and it is shifting sooner. The detent cable is disconnected from the carb right now because I thought it was stopping the tranny from shifting. The line out from the vacuum modulator is a rubber line. I have it zipped tied away from the exhaust. I made sure it doesn't have any sharp bends or kinks in it. I know the truck is shifting into 3rd when I let off the gas because i can put it down into 2nd and feel it drop down - same going into 1st. It is just holding in 2nd when I am on the gas - even slightly.
