    Just bought nbs 2007 2500hd. i am hearing rumors that the trans is made by allision, just has a different sticker on it. Switched from the 03 to this, and does it ever shift different. Any one else feel that way too?

    Yaa no not even close to the same tranny. The only thing common between them is they are both available in a GM truck, oh and both spec Dextron VI
