question on kick down linkage........

My 67 has a 340 not sure what year and a 727 trans. On the kick down linkage is there just 1 adjustment on the horizontal linkage that goes to the carburetor (part #12 in my manual) or is there another 1 on the linkage that goes to the trans pivot arm? I have 1 on the vertical rod that goes to the lower bellcrank, but I was told that there should be one on the rod that goes to the trans. Any help is appreciated,thx.
