My transmission seems to be slipping...torque converter??

By picture I figure you want to see the flakes? I have the linkage set where each button bottoms at the detent on the rooster comb with no binding. The kickdown i do have a question about. Is the pressure switch supposed to be engaging the moment the throttle is pressed or is there supposed to be a little play before engaging? I currently have it set with no play. I will get a pic asap. Thank you for your patience...
