ok well i put the car into drive and it goes in hard then i accell slow to 2and and then the rpms drop to 1000 and the tac bounces a couple hundred rpm even when its hot i think the torq converter is locking up so what would cause hard shift and torq converter lock up

sounds like maybe your trans is going into limp mode causing it to lock it up so it doesn't over heat and also shifting hard so it doesn't heat up as well. I could be wrong. We'll wait until someone else.

If you have a tuner.. reset the code. No tuner then pull the battery cables for fifteen minutes to reset code and try again.
