So I do not have an extended warranty right now. The PO did. Sorry for the confusion. I could have transferred it but it only had a month or so left. I was offered one through my bank, but it was an extra $45 a month so I decided against it. Kicking myself right now. But this being my 5th BMW, it would have never paid off before (I did blow a motor in one of my M3's, but it was supercharged, doubt warranty would of paid for that, lol). It's a shame this has been less reliable than any of my M cars in just a matter of 2 months.

So I don't feel paying BMW 7 or 8K for a new transmission, I'm not going to pay almost half of what I paid for the truck. I'm trying to just figure out worst case scenario if the tranny is bad, what is the typical rebuild cost you guys are paying?

And yes I will try changing the fluid and filter first to see if that helps. And will be getting it checked out by a transmission shop if the fluid doesn't work. It would be nice if it was the valve body, because I think I could handle doing that myself.
