Being in Australia and wanting Xfire SRT6 service could be a big issue. There are even less of them down there than in the States... I have found ONE dealership with 2 good techs in my area...a suburban area of 3 million people of Northern California... So, I have a bit more to choose from... You might have better luck finding a solution on this board and then just telling a competent mechanic. There is a download somewhere on this board that has the full service manual though. Start with that as a reference and put it on a CD to deliver to the technician you ultimately choose.
