Just clarification for anyone looking, 5155177 is the SRT version so it will be preloaded with the 3.06 ratio. 5153332 is the 5.7 version preloaded for 2.82. Easily changed with a tuner. GLWS.

Benefits to This? Assume it will work in my 2011 Pursuit?

1. It will not, in fact these pretty much won't work with anything after 2007.
2. The part they left out with the "optimized" shift schedule is that lockup happens in 2nd gear...in an 05-07 it somewhat changes the nature of the car even without a cam.
3. For anything 08-14 (and later Pursuits) a custom tuned TCM would be required.
What I have noticed is that maybe the exception of the hold in gear autostick feature, my 2012 SRT TCM acts very similar to the MTCM I had in my 06 R/T. If you wanted to try something like that I'd find a 12-14 SRT TCM and swap it in (NAG1 TCM's are swappable within car families without any kind of VIN update or programming required).

well this was on a 2009 challenfger SRT 6.1, i looked on another site that was talking about 5155177 these are good for 2006-2010 6.1, but but some are also swearing they work on the r/t models as well

I've heard an equal amount of people say it worked on their newer vehicle and didn't. There was a CAN bus change in 2008, the Challengers were born with it. It's hit or miss 08-10. Only one way to find out!

AND THEN i also heard anyone with a NAG-1 5spd tranny. and basically it is for a NAG 1 5spd.

Always wondered if it would work in other NAG1 applications.
