Why would software that worked for 35k miles suddenly not be adequate? I guess my 09 has the first fix by virtue of its build date, and has had a tranny burp just once, about a year ago and nothing since. Self healing software maybe? My money is on a mechanical/sensor glitch.

My build date is 11/08. I may be wrong, but I assumed the better shifting upgrade or whatever it was had been installed at the factory.
