I think I've figured it out...

Apparently the consensus is that the Mercon V is the best out there... currently. So... I'll stick with that since there is currently no way to drain the torque converter. Otherwise I would be mixing different types and that usually leads to some type of disaster.

As for the added capacity... +2qts to 14 (13.8qt capacity according to specs) adds roughly 15% volume. Once a tranny is at temp... it's at temp. Cooling isn't a factor of volume but rather of heat transfer... hence a transmission cooler. The added capacity would only be of benefit during a drag/sprint type situation. It takes longer and/or more heat to raise temp of 16qts than it does 14qts. A larger pot of water so to speak. So, since I'm not going to be running 1/4s at the strip... the added expense of fluid and a $200 to $300 pan have no performance benefit and only hit the wallet harder. Greenies that could be better spent/applied elsewhere.

Thanks for the input...

I plan on post w/pics once install is completed. I ordered a drain plug for the stock pan from Jegs so as soon as it arrives I'll make the mess. I'm doing the drain plug to prevent future messes during fluid change intervals.

Thanks again y'all for the thoughts/opinions!
