Ican Anyne Help Me

I know you all are really good with transmission problems,but I'm terrible.Can anyone tell me what they think happend or if my transmission is completly shot(hopefully not).I was test driving my 98 dodge ram 2500 aotomatic,so I could tell a mechanic what my transmission was doing.What happens is when you take off the transmission will shift from 1st to second,but for some reason it will not go into the next gear.I tried it with overdrive on and off.The only time it would go to the next gear was when I tried to put in to nutral while driving and then put into drive,but while driving it I had to go up a hill,and when I tried, it went about 50 feet and then then you herd a loud noise.You could fell it to.It sounded like and felt like while going up the hill.It felt like it just sapped and would no longer go foward.It was like it went from drive to nutral.I let it role back on the level street and then tried to put it in drive again and it will not move,but it will work in reverse.Can anyone help me out with what this is or what might of happend

thanks everyone

Check the trans fluid level. Let us know what color it is if you find any.
