Okay first post but have some questions. I have a 2003 extended cab gmc sierra dually hd3500 6.6l duramax with the zf6 manual. It is old but I am going to do some things to make it better. I bought a 2004 chevy suburban with a nice loaded out interior. I want to swap everything from the front seats forward to get all the features. Does the bcm have anything to do with my manual transmission. And if I take the time to do the swap will I have to get anything reprogrammed by the dealership. I know it will be a big pain but the ending product should be sweet. Also it will have the shifter in the center console. Already have the trucks hoping to find someone who has done it before. Hope this is the right section could not find a post specific to this.
