1999 Dodge Intrepid stuck in second gear

99 dodge intrepid, 170k miles.
symptoms: speedometer stopped working, and on the next turn as I slowed down the car stalled. I put it in park, restarted, and drove away. I realized that the engine was racing, the car was seemi. Ngly stuck in second gear. I drove it towards home and the first couple of times that I slowed down it stalled, after a few miles it allowed me to idle without stalling. It still races and is seemingly stuck in second gear.
any ideas?
i checked the fuses and they seem alright, the transmission fluid is normal as well.
