You are mighty quick to blame the update and the vehicle. Given the almost uniformly negative content to your postings, in this thread and others, I seriously question your objectivity and reliability to dispense advice in a controlled and unbiased manner. Perhaps a simpler explanation, but not one that would give you yet another opportunity to vent your spleen at Chrysler designers and programmers, is that your dealer didn't read the TSB carefully enough and reflexively erased your TCM's memory after the update--the previous recommended protocol--and your Jeep is now relearning your shift points. This would explain what you are observing.
I had the update performed and reminded my dealer not to erase the memory. I have noted improved shifting at lower gears and no discernible mileage declines. I think it is a good and worthwhile update.
You obviously hate your Jeep and want any reason to get rid of it. It is understandable given all of your problems. But in light of your obvious bias, perhaps you aren't the best person to provide advice to people who like me want to keep their Jeeps and are trying to make the best out of their purchases despite some unfortunate issues.
