Hello and welcome to JustAnswer!

If it takes off in second gear and shifts fine other than that then the most likely cause would be the governor transducer. A sticking 1-2 shift valve is possible but not nearly as common as a bad transducer. What usually happens is the transducer will show a lower pressure than it should and it causes governor pressure to remain high at stops when it should go to zero. This holds the 1-2 shift valve in the second gear position.

If you have a scan tool and trans pressure gauge you can check the accuracy of the transducer. Otherwise I would recommend replacing it with a Mopar part.
