U1024 is Data Link Communications error on the TCM. Prolly gonna have to bring it in. You can't erase that code because it is being instantly regenerated because the problem is within the actual system that comunicates with the device to interface with the car.

Could be a loose connection or it could just be a bad TCM. There could even be something with the uprev device that is causing your vehicle to throw the code I suppose.
