Help please,throttle lever

Have you unhooked the throttle pressure linkage from it to see if it's in the lever or the linkage?

thanks badsport for the reply,the linkage has been disconnected and removed, I was planning to use the lokar cable set-up, would the engine have to be running in order for the throttle lever to move even tho nothing is hooked up to it? Also, there is only about 8 pints of fluid in the trans right now, had to make new cooler lines, didn't want to fill it up yet due to possible leaks.
