2013 SHO +pp
2013 pp SHO, I am looking to replace the rear differential fluid wanted recommendations and if it requires friction modifiers added, if so which part number. My 35,500 mile car is currently getting a new PTU so that should be good for a year or two. I will take car to my repair guy who will flush and fill trans. He only uses synthetic but is there a recommendation for synthetic trans fluid too? Thanks for all replys.
