My 2008 town and country wont go in drive or reverse.

I was driving it on the free way I head the cruise on and try to pass someone with out turning cruise off and all of a sudden it slowed way down and I hit the gas pedal and all it did was rev up the motor when I stopped I tried it in reverse and got nothing did the same thing just reved up student move so now all I can drop is put it in drive or reverse and it just revs up no movement I replaced the speed sensors and it didn't help it what should I do
