This jerky transmission thing is a serious mystery because my 2022 ES 350 F sport is smooth as butter, even when accelerating from a very slow crawl. The only time I feel the shifts is when I first start the car and it hasn’t warmed up but as soon as the car is up to temperature, it’s butter smooth.

Why isn't there a TSB or some corrective action taken? This is now almost 5 years but I must say that I'm not surprised at the lack of service on this and other ongoing issues such as the dash material that mars easily starting with the 2019 M.Y. In my opinion Lexus does whatever they can to avoid fixing what they deem "minor issues" or issues that would cost $$$ to rectify. This, IMO, is one area that Lexus fails at...

Everyone with 2019 - 2021 who has felt the harness from the transmission should ask for the "update" in your next service from Lexus to see if it help and let us know. I think there are only a small portions of 2019+ Lexus ES 350 that have this issue and it should be fixable by software... there is no way Toyota/Lexus make this horrible tranny at first place
