I had the tranny software updated a few years back to deal with this issue. It still happens from time to time but MUCH less often and very infrequently.

I'm still suffering from the tranny slam and it seems to be getting worse. According to the dealer I have the latest software update.

same here, i've got the software update and it didn't do squat. the only upside to the whole issue is that i've been forced to come to a complete stop at every stop sign and that keeps the police happy.

The only thing that seems to help is to make an appointment with the dealer. It never fails that the tranny behaves better the day of the appointment and the dealer says there's nothing wrong.

Hmmmm. Mine isnt all that bad. i might just try and get the adaptations reset and see if that helps.

Software update was done two years ago on mine and very infrequently does it "only upon start with cold engine/trany", no issues during stopping though.

Hopefully I might have the same luck :-)

The only thing that helped me was to replace the trans. Fortunately, the dealer did it under CPO warranty.

So many mixed responses around this. I'm a little nervous about having the update, but if it make it better I dont want to miss out!

Likewise, since my trans was replace under CPO back in June, I've not had a single bang. (crosses fingers)
