well, there are a number of things that could be wrong with your tranny. you say you have 722.422 so it sounds like its the vacuum controlled tranny. what year is your car? i would start by checking your vacuum lines that go from your transmission to the upshift delay switchover vavle and also check the lines that go from the tranny at the modulator to the intake manifold. have you checked your tranny fluid level? is it low? high? is it red? black? i would say that a transmission fluid change is probably a good thing to do at this point anyway if its never been done.
so the transmission is stuck in second and only second? do you have a mode switch for your transmission?
