Should a mod. valve vacuum line be hooked up directly to the intake or to a ported source on the carb? If carb is the answer,which port?
thanks

the modulator valve should be connected to the intake manifold directly, usually there is a vacume tree just behind the carb,ported vacume will give the wrong signal to the tranny

this may be a dumb question, but what does a modulator valve do?
