99 Durango won't shift out of 1st gear

[urfavejerzeygrl]

I have a 99 V8 Durango with 123k mi on it. The trans. fluid was flushed last week and this week when I was driving it wouldn't shift out of first gear. I drove home at 4k rmp and 15mph. Took back to the gar that did the flush and they said 7 comp. codes came up. Reset comp. Govn pressure sensor codes still came up and this was replaced. Car still won't shift. What could be the problem?

i had the same problem only mine only done it when it was low on gas ..like 1/4 tank or less.. and like he said i replaced the speed senser at the rear of tranny and wala problem fixed... it killed me for weeks trying to figure it out i was told 100 times it needed a 2 grand rebuild...it was 18 bucks @ autozone
