I have a '10 Laramie CC 4x4 with 3.92s and know the R/T has a more gear in the rear but the transmission programming on that truck is more aggressive and much more crisp stock vs the slop I have to deal with on mine. I've looked into 545RFE hardware mods but think mine is just sloppy based on the stock programming(and don't get me started on the 2nd/ 2nd Prime ratios).

Any thoughts? Know Diablosport and SuperChips have some ECU code tweaks, have driven one of them and didn't really notice much difference honestly. After 8mos and 6Kmi I still like just about everything on my truck minus this tranny. I'd swap it out in a minute given the chance to try something else...

Any thoughts/feedback appreciated.

 

Here you go.... Your truck will be VERY different.
