Hi, I just bought a 2011 Chevy Cruze with a bad transmission and will be replacing it with one out of a salvage yard. I am only finding so far that the filter is replaced on a rebuild and that it is located someplace behind the transmission pump. It looks like Oreillys has a filter with a gasket. Can anyone tell me what I need to do to change the filter before I install the used transmission? Also how much Dex 6 am I going to need? thanks for any help you can give me on this!
