Kickdown Linkage

Trans lever cloder? I am still a little confused. I will be looking at my car from underside this weekend as I finally have access to lift. What confuses me was if it is just a simple adjustment why trans shop could not do it, or did not when they had it as I asked them to check it out. They just told me it wasnt functioning properly. I havr the 65 service manual and it only talks about adjusting cable from the top? It seems to be correct when compared to picture in service manual at carbside? I am smart enough to adjust carb linkage but beyond that I am somewhat clueless. I seems the two cables must counterbalace themselves to adjust properly? I see both move freely at carb end, but do not know what to look for at other end? I have always had trans shop deal with such things, it makes me feel stupid to some degree as I cannot picture corrrect set up in my mind or see one on paper. Service manual does not show this?
