ok ive got a k5 that had a 700r and it died, took it to a shop and decided htat for a whopping $200 more i can get a brand new 400 instead of rebuild the 700 did that. Now this is about 6 months later, i am not ever remembering the trans EVER having any form of kickdown. I was looking around today and inspecting the trans. i know the little spade is for the kickdown there was nothign attached. IS there any possibility that a vacuum siwtch mounted inline of the vacuum to the modulator could do the kickdown? bc there is a vacuum switch that after ive checked it is not openign or closing regardless of vacuum. In other words can a vacuum switch be used to control kickdown to the modulator or is it only electric? and this switch WAs for my lock up converter... Ill try and explain how its set upa nd ill get pictures tomorow. Behind the carb, theres a vacuum port, on hose going to a T one line from manifold in, one to modulator, and one to this switch. On the other side of the switch is a 2 spaded Female plugin. Anybody got a clue as the the 1st question or wtf this swithc is? i went to napa and discount and nobody could give me a straight answer, they enven ran the number. thanks guys i REALLY wanna have the power of kickdown...w/.o spending the $50 for the B&M kit. the switch resembles this one except with 2 female connectors not male.
