Just had it in for its first oil change. Told my SM about the TSB for the jerking. He said he’d have his trans guy check it out. Sure enough the intermittent jerking happened when he was driving it and he noticed the hard shift into drive and reverse From park, he said there was a TSB for that as well. So after the updates and reflash I drove it today and noticed a marked difference on how it shifts and drives. So far pleased with this update.
