I did a drain and fill twice using Mercon SP, she's running real smooth. I did round out the hex hole on the plastic drain plug, I think I will just drop and replace the pan at 60K.
Btw, I found this on another forum regarding Valvoline Maxlife ATF. I think I will use it next time as it is a full synthetic that satisfies Shell M1375.4 spec, among many others.
