300m w/100k miles. Trans seems good but shudders in reverse. Any adjustment?

With all the tranny problems, electrical problems ,look on the bright side. Keep note of all the problems your having as Chrysler has finally admitted all 300Ms built before 2008 are under recall due to their faulty ignition switch. Untold thousand upon thousands transmissions have been destroyed while running and key switches failed. This is going to be interesting to those of Us who still own these models. Good Luck and keep an eye out for your recall notice. If you don't get one? Call the dealer and demand to have your name put on a list and notified when they figure it out. I called one and they ask if I received a 2nd notice yet. I thought no not yet but I'm waiting with my $4200.00 dealer bill!
