    It sounds like your kick down cable or Throttle Pressure Valve is stuck in the power position. Check to see if there is a vacuum line to your trans, if there is then make sure it is on correctly. Also take it off and make sure no fluid comes out, that is a sign that the Vacuum Transducer is broken and needs replacing. If no vacuum line, then make sure that the kick down cable works well, it is a cable that goes to your throttle body next to the throttle cable but it goes down to the trans. It should operate SMOOTHLY when you pull it. Best of Luck!
