A8 reflash
15 Z51 A8 build date 10/14. Don't perceive any major shift problems. But occasional first hard cold shift and hard downshift also before up to operating temp. I don't have any reference on how good this tranie can behave so I'm wondering if I should it re flashed. Does reflash actually improve function? I will say my wife's 14 ATS has a much smoother and crisp shift point thru the gears than the vette.

You guys who've had the reflash done, how long did it take them to complete it? It's a two-step process: Reflash and "fast learn" procedures. The latter step requires the tranny fluid to be between 167° and 185° before the scan tool will start the process, and I've seen my car exceed 167° only once since I've owned it. It usually peaks at around 150° even in these 100° day we've been having lately. I'm wondering how the dealers are getting the trannies up to temp, but I suspect the techs are taking them out for an extended joy ride. I think mine would take at least 20 miles of spirited driving to get it up that high.
