Torque converter judder caused by prematurely worn ATF. Software update prevents the ATF from wearing prematurely in the future, the 3x drain and fill gets the worn ATF out of there.

Ask a dealer about it, if your vehicle needs it they can do it.

Are we talking about this bulletin? If so, its not about stopping ATF from premature wear (only way to do that is keep it in Honda bottle), but about reprogramming TC lock up clutch.
