It was a month since my 2010 got the judder transmission recall PCM updated. I am experiencing slightly worse mileage from 21 to 20 mpg (~5%). I don't want to make this a big deal, I just notice because I have been doing the same routines every week. If that's the price to keep the TC healthy, I can live with it. I am just wondering if any others notice the same and what might be the reason behind it. Thanks!
