Transmission Help?

[ZeRo 91]

Have a quick question for you guys that I desperately need help/guidance with. I have a 02 Altima 2.5 (automatic) that I can't get to engage in gear. Here is what happened: last week went to put my car in reverse, which it went into fine, then put it into Drive which was also ok but then when I accelerated the car moved maybe a couple feet and then just stopped as if it were in neutral. I can here something just spinning (transmission trying to engage?) but nothing happening. I am able to move the shifter through the various gears but nothing is happening. Any help on maybe what I should look for or listen for or what to check would be greatly appreciated as trasmissions are not something I am all that familiar with.

Thanks
