When I had my R24 recall done (end of October) I asked the service manager if they did all of the updates, he assured me they did. I suspected they didnt. So I took my car to a different dealer this morning, one closer to home where we just purchased my wife's 2016 Cherokee, and had them plug it in to check for updates. They confirmed there is a PCM and TCM update and that I'd have to schedule about 3 hours to account for the learn process.
I have a 2015 V6 FWD and I'm noticing a harder shift from 2-3. My wife's 2016 Cherokee ZF9 is smooth as butter.
Has anyone had these updates and regretted getting them?
