Not all GM transmissions go that far without troubles. You got one trans that has an issue but what about the thousands of others that have no problems. Just because a bulletin was issued doesn't mean every trans is bad. It just means they have seem that arise in some transmissions and the update can sometimes help but not every time.
Do you think that because they didnt do the quicklearn after the update that its a slight possibility thats why the update didnt help initially, or do you think the trans is still bad? I just hate it if its bad because it does so well right now, and even before the quicklearn, it upshifted through the gears perfect, smooth, didnt slip, no delayed engagements...just the harsh 4-3 downshift..
