YesI believe the P5155177 is for SRT's only.
Most results like myself were on 2005-2007 cars, the 2009 R/T's are still a mystery.There have been real world results posted from 5.7 and 6.1 owners using these TCMs over on LXforums, you guys ought to check it out.
If I was assured the xxxx177 would work on a 2010 5.7, I'd buy one. But I have not read a 5.7 owner use the SRT TCM.
It's kind of like with the Predator, it has no options for a 2010 tranny, cept' firmer shifts.
rofl, overstatement of the year....I have seen this as well.... One of the things that made me think it would work, but then no one has used it...I am still hoping that Hptuners will get done and then it will be no problem!
