My 93 Ramcharger won't shift from first gear. I noticed it was holding on to first gear longer that i liked for a couple days, now it won't shift from first at all. I changed the fluid and filter, but it didn't seem to help. Still won't shift. It also doesn't like to shift to park. I have to shift it to park real fast, otherwise it just goes to reverse and stays there. It did all this at the same time in just a couple days. Is something out of adjustment? It is a 4x4, 4 speed auto, behind a Magnum 318, if that helps.
