i am not sure i follow what kind of tranny are you putting in there? a 2wd ss tranny is the same as the awd ss tranny except the 2wd has a tailhousing bolted to the end instead of a tcase. if your putting a different tranny then the 4L70e in your suv then you may need a custom crossmember and driveshaft. do to differnces in size and shape and crossmember bolt holes
