I looked around a bit, but even my manual doesn't say what the capacity of the TC is. I have a 2011 Rubicon if that makes a difference. Also, I have recently switched my motor oil to Amsoil, and I would like to use that in the TC and diffs as well. On Amsoil's site, there appears to be a few different choices. So I guess my question is, what is Amsoil's ATF+4 equivalent?
