I just recently put a new flexplate and converter in my stang... it ran fine for probly 100 miles... but now whenever i gas it revs up real high before it starts going... its a roadrunner 2800 stall... if im at a stop... and hammer it... it revved up to 5500 so i finally let go... that car didnt move... and even when im cruisin if i let go of the pedal and push back down it revs up again even at 50 mph... do you think my converters defective or maybe the tranny cant handle the stall??? HELP PLEASE!!!
