99 Avenger ES v6 auto 120K

I was backing out of my parking spot at work and when i put it in drive, nothing happened.  the parking lot was on a hill and when i put it in park, it kept on rolling.  i let it roll back into the spot and turned it off while my foot was on the brake.  i started it back up and when i shift it into any gear, i can hear something happening but the car just keeps on rolling forward and when i put it back into park it sounded like it tried to do it while the car was rolling.

unfortunately i was 45 miles from home so i just had it towed 3 miles down the road to aamco ($75!).  they said it was definately a trans problem and would be $1500 to fix and that may be more or less depending on parts but they didn't look at it unless i wanted them to and that would be 400 if they didn't fix it! so i had it towed to a relatives house 25 miles away for another cool 250 bucks.

i think can rule out a cable cause i can hear something moving when i shift it into gear.

i hear that even when the trans is bad park will still work and i can definately hear park stopping the trans.  i had a torque converter go out in a car before and park still worked so i don't think its that.

i think (read 'hope') that it is a snapped axle. 

any thoughts?

thanks.

no, there was no fluid.  i'm gonna see the car saturday and i'll take a look at the axles and the cable.  the car has had no problems up until now and i really do no want to lose the car because of this.
