2001 Explorer Sport shift problem!!!

[xplodersprt]

I have a 2001 explorer sport. i was driving some firends around one day, and all of a sudden, when it was supposed to shift into 3rd, the engine revved up and OD light started flashing. I stopped, shut the car off, and started it up again.. only to my suprise that it did it again. It starts at about 25mph and wont shift at all. I have to drive around in 2nd gear, just because i cant drive in DRIVE!!! I dont have $2500 laying around for a new tranny.. so thats out of the pic. Any Ideas?!?!?!

I'm having that same problem with mine and can't figure out why it won't shift. Have you figured out what the problem is with it yet?
