Well, I've driven the car another 10- 15,000 miles or so since the post, mainly high speed highway from Fresno to Oakland and back, and for the past 3 months, its only acted up once. (very briefly) I think I'll drain and fill again.
As mentioned above, there isn't a way to "drain" the torque converter. unless you go throught the trans cooler lines, which, in my estimation (as a former 12 year dealer tech (on Dodge) is asking for a can of worms.
An even larger can is the post above in my own opinion. Mixing fluids, and "trying" additives is a risky chance I'm not willing to take, unless the thing is just so bad you can't drive. Its like going from Valvoline to Penzoil. You're gonna get a smoker every time....
OEM fluid is still hard to beat for what ever car you own, and this comes from a tightwad-mechanic..
End result, is that I'm happy with the outcome, and it's not driving me nuts anymore. (upon looking at the Smart Blend mentioned above, it might be something I try, just as an addition to my next drain and fill..)
