Got "2nd notice" Anyone had actual experience with the "fix" (before and after)

Ask FCA about effets? HAR..tried that...Nobody knows nothing!

Still holding out on mine. No one has explained if the mpg will increase or decrease.

mpg will decrease. performance will slacken, throttle response will be worse. there are no positive effects to be seen. This is SOP.

I had a Robot call last week about this.

After a couple of months, I can confirm, worse mileage, effed up shifting points in tow mode, near total disable of manual shifting mode, power OK, already poor throttle response seems even more delayed, absolutely sucks down the DEF. Regards, Bill.
