Re: Trans Update
Regarding the ECM/TCM update, they just did my ECM at my first oil change. Afterwards, my odometer racked up over 3 miles for every mile. They did the ECM and TCM together at my next visit and now it's back to calculating normally. If they do one and not the other, I'd keep a close eye on your odometer. My service tech said the error was caused by doing one update and not the other. I'm guessing they have either fixed this issue, or are always doing both updates together.
Regarding the knocking sound, I'm getting it as well -- within a block or two of leaving my driveway. I was thinking it had to do with the door locks automatically locking at a certain speed or after a certain amount of time like my jeep used to do. But I'm not so sure since I think that happens the Outlook when it's taken out of park.
