Had a shop in Albuquerque, NM build up a C4 for me and guy says, “just use a good synthetic ATF and your good to go”. So I buy a case of Mobil 1 and a few thousand miles down the road I start looking closer at what other folks with C4s are using and it’s all over the map. And to top it all off, everyone I talk to has a different opinion, including the transmission shops. So here’s the poll: What ATF are you using in your C4?
