1995 Dodge Intrepid 3.3 automatic won't shift out of 1st gear sometimes. check engine light comes on. have gotten code 33, 22, and 21 but some of the codes may be old and just need to be reset...any suggestions? The main problem is being at a stop light and car won't seem to shift from first. rpms go to 3000-4000 and sometimes a little over, but sometimes it shifts ok.
