Speedometer Freak out

(2008 LS4 GXP) So i'm in drive at a stop light, brake on and my speedometer jumps up to 35 then to 50 then down to 12 and so on. If I put it in park, it quits. But ill be sittin there and it jumps around then, when i go to drive while the speedometer is jumping around it almost feels like the tranny is slipping. I told dealership about it, I still have warrenty, and they said it didnt throw any codes so they have no idea. does anyone have any clue whats up with my car?
 


thats what im getting from reading up but thats on older models, havent found any ls4 with the same prob. im droppin it back off tongiht. Its getting worse, and im pretty sure its affecting my tranny, would a speed sensor make it slip?
 
The speed sensor is on the trans. I had my settings wrong for my speed sensor in my tune and my tranny felt horrible. It would get ready to shift, then lag for a couple seconds then slam into gear.
