Eaton TrueTrac

I'm running a TrueTrac in my Strange 60. Cass (Dr. Diff) recommended it as a good upgrade. Haven't put any real power to it yet as I'm still building my 408. It's got about 500 street miles on it, and I need to get the break in oil out of it. So far, it's been flawless. What do you need to know about it?
