AODE HELP PLEASE

I was driving today and the tranny started to act funny...I would have to push the accelerator down more and more to get the gears to change. Now it will go through 4th and then when it is supposed to go into O/D it just revs up real high like it is not in gear...When I put the O/D Off it ran fine just without O/D of course...I have no idea what is wrong with it since I have never had a problem like this before. I am at a friends house and do not have my chiltons so i cannot look it up either. I tried searching the forums for this but there was not much I could find. Any help would be greatly appreciated because I am stuck in Maine and have to drive back to New Hampshire and do not want to drive before this gets fixed. Thanks before hand for the help, everyone here has helped me quite a bit. Thanks.

I had this problem with my AOD, except that it happened to me on the 1st to 2nd shift. Check your fluid, if it is low or dirty, it will cause this to happen. I also bought a bottle of lucas transmission seal/slip fix, and it solved my problem. Hope this helps a little.
