Will not shift out of 1st

The kickdown probably was too tight... it reached it's full travel before WOT. Also, due to the shifter linkage on the Lokar shifter I'm using, the kickdown lever can't return all the way. It releases far enough so that there's not any tension on the internal spring but it could travel farther forward if the linkage wasn't in the way.

So, would having the cable adjusted too tight or the lever not being able to fully return cause it to not shift (even when I manually put it in 2nd)?
