Riddle me this...

So I think I found the source of my problem and I'm a bit worried. As I was messing with my carburetor I checked my Lokar kickdown cable and it was loose at full throttle. It shifted nice and firm at part throttle but at hard throttle is where it was slipping. Now I'm really worried because this is probably why I was turning so many rpm's on the highway. I didn't do it much but I realize I've probably damaged the transmission a bit if it wasn't getting enough pressure from the kickdown. I'm going to readjust the linkage and see what happens but at this point I'm pretty worried. Crap, crap, crap!!! :BangHead:
