Hello,

It sounds like you have a problem with the transmission control unit. To be sure lets run the codes to see what comes up. here is a guide to help us fix the problem:

if nothing comes up lets do a CAN scan which is the future of car repair. here is a video you can get a CAN scanner from Amazon for about $50.00:
