727 throttle pressure adjustment

Whats happening is the lever, when disconnected from the cable, that is adjusted to WOT, will continue approx. 1/4 inch to the idle position. I did put a spring to be sure the lever returned to its furthest travel to idle. I belive I will try the adjusment as to shift speed. It seems to hold second until the the throttle is let up, the shifts. Thanks !!
