Assuming you don't have a part throttle kickdown setup you usually have to pretty much mat the pedal to get it to downshift.

Have an assistant hold the gas pedal to the floor for you. Crawl underneath and look at the TP lever on the tranny. Disconnect the cable and make sure that the lever has no motion left WOT. If there is any free motion left, adjust your cable. Check to make sure it doesn't bind/interfere with WOT afterwards.
