Check vacuum lines. I had a similar situation in a Ford Fairmont and it was a tiny pebble in one of the vacuum lines blocking it.

Sounds to me like it won't downshift after it warms up. Have you tried pulling the shifter down to 1st?

That pretty much confirms it then you got a computer problem.

how do you know its in 1st for sure, from your discription it sounds like its taking off in 2nd. Check linkage from colum to trans. ?
mystery - so when you get going you can shift from 1st through all the gears? what speed and rpms can you get taking of in 1st

well truth be know i dont really know but i do know once it does go it shifts through all gears and you can put it in 1st and it will do the same thing.......now what are the possibility that a wiring problem could be causeing it because the computer wont communicate with my scanner even after changing the computer so that points me to maybe a broken wire between the pcm and the eec connector or at least thats my thinking anyway
