If there is future software update, I wonder if this occurs remotely or if it will require a visit to the dealership. A friend with a new Tundra told me he had his truck into the toyota dealership (no shifting issues)for routine service maintenance and they "reflashed" his transmission software due to an update.
One thing I do miss coming from an F-150 to my GX is the ability to monitor software update status, know when they're available, and in some cases flash them myself.
