I just picked up a 95 formula and in order for it to shift out of first gear you have to be doing about 25-30mph and let up completely off the gas and it shifts right away. All the other gears appear to be fine. So far I replaced all 4 shift solenoids, pan gasket, filter and fresh fluid. After that it got a little better but still does it so I did more reading and people say to check the tps so I replaced that also and once again better but still not how it should be. My next step is the 1-2 shift accumulator I guess the springs can break or be wore out. Any other suggestions? I'm stumped and am trying to avoid getting a rebuild done but I will if I have too.
