I am new to this site and have an extremely limited knowledge of the GP.....however, a friend of mine was having a similar problem with his dodge truck and a local transmission company told him the same thing. Same outcome as yours. In the end, it was a faulty transmission module (brain) that was the culprit. Hope this helps.

First things first, check your tranny fluid.
jamal313,
It is difficult to say. A few suggestions are an issue with the valve box in the transmission; another could be the mass airflow sensor. These are just suggestions, it is not a diagnosis. It would be best to take the vehicle in to be inspected by a certified technician.
Please keep us posted.
If you have additional questions, please feel free to contact me.

are your motor and trans mount in good shape? all the bolts went back in when you swapped it?
or is more of a slip and bang into gear?
so did they put another trans in it or what happende in this sitution?
Please keep one thing in one thread. Making multiple threads makes it tougher for those that help you to keep track of everything relating to the one problem.
