Very exciting. Now to fight with the dealer to convince them that it exists. Haha

Got mine done today since I happened to be getting some service done. I can tell the difference especially when downshifting coming to a stop. It is a lot smoother than before. All shift feel smoother and more refined in auto mode.

I have not tested out the differences in other modes yet, will advise.

@Jbjones85 , Westgate didn't give me much hassle, just told them there was a fix for rough shifting in the transmission and provided the TSB#.

Re: Flash: Transmission Shift Enhancements - 2014 SRT

Got mine done yesterday. Very noticeable difference on both down and upshifting. Much smoother when coming to a stop now. It will be interesting to see how or if it changes when it re-learns my driving.

Re: Flash: Transmission Shift Enhancements - 2014 SRT

Probably prolongs tranny life. Doubtful they'd give us anything useful..
