CPO Transmission Replacement

[SWATH]

So I took my X in for the "usual" transmission slamming about nine months ago. I have a CPO warranty through this year and the dealer "reset" things and loaded the latest software update. Things ran well for about seven months and then started to get bad again. After one particularily hard slam (wife's knees hit the dashboard!), the transmission started to "skip" when I take my foot off the gas to slow down, even slightly.

Finally get tired of it after another slam. After lots of research and discussion with my Indie, I go ehad and take it to the dealer to see if anything comes up since I have never gotten any error codes when this happens.

Now you might think being the dealer this would be a really short story. However, after a couple hours, the service manager calls and says they have opened an engineering case with BMW. Less than an hour later, he calls again and says BMW has determined it needs a new transmission and it will go in tomorrow.

So should I be worried? Months of no error codes, then a short visit and a new transmission without even a peep from the dealer about it.

We'll see what tomorrow brings with a new transmission and I'll post an update.
