Your are in what is called Limp Mode. Which the vehicle goes into when there is a problem with something to do with the tranny, a sensor, selonoid or the computer, so you can get it somewhere to be looked at.
Is your check engine light on? If so have codes pulled, your local auto zone will do it free.
I will say in my experience with this situation it has been either the Input and/or the Output speed sensors or the Tranny Computer.
Post codes here.
