I think it’s code for fixing one thing and breaking something else.

Not sure what to make of this bullshit........"substantially improved shifting" implies the old design must be deficient. However, I have two of them and I've never felt a better transmission before. The Range DFM module also improves shifting, whether intended or fortuitous, that's where I'm at!

My 1st to 2nd feels a little off/jerky but every other up or downshift is extremely smooth. I’ve heard others point out the same thing. Too bad we gotta fail before we get the improved crap. All of this really points to either rushed or poorly field tested.
