Many Chrysler's have what they call a "Limp-in" mode where the computers (control modules) will hold the transmission in 3rd or 4th gear. This allows the customer to be able to make it to a dealer/shop/home while minimizing possible damage to components. With your check engine light on, you'll need to have the computer scanned for trouble codes. There is a service bulletin for a surging problem between 40-50mph but I'm not sure that is the symptom you're describing here.
