Had the transmission fluid changed 11 weeks ago and the guy forgot to reattach a vacuum hose causing CEL lights to keep reappearing, fixed by changing air filter etc till this last time I discovered the hose. While working on it I think I dislodged something as it wont shift out of 2nd I think (or 3rd), almost like the hold switch is stuck on. It won't drop to 1st unless you manualy shift it there, starts out in 2nd and stays there. I had dropped a clamp on top of the tranny when I was checking out the air intake and put a rod down there to dislodge it. Did I unplug something? Seems to be electrical, but I've read on here about oxygen sensors, did prolonged bad air/fuel mess up, or is this all some weird coincidence and tranny has problem. CEL went out (had guy clear) but shift problem still exists. Any help appreciated.
