He posted those results not long ago...do a search.... interesting for sure. The ONLY reason I'd change from stock is the rust issue with Ford's fluid containers. Oil, rear end, tranny- it seems they are all rusting pretty quickly! I sprayed mine with Fluid Film and it seems to be working real well!

I know you want to believe it, but science is science. It is true whether you believe it or not.

I look at it like this. It takes X amount of BTU's to raise the temp of one quart of fluid 1 degF. If you add 5 additional quarts, you have essentially added heat carrying capacity. Those same BTU's will not be able to increase the temp to the same level as it did with the single quart.
Another way to look at it on a grander scale. Look at a CNC machine. Imagine if you only had 2 quarts of the cutting fluid, (which is used for cooling.) At some point the fluid would get up to a stable temp. Now increase the capacity of the cutting fluid. The temp will be less as you increase capacity.
Now adding 5 quarts of Mercon SP may not add much, I believe it adds some BTU carrying capacity. Now, add the increased surface area of some pans with fins or tubes. I believe you will see a difference, it may be negligible, I don't know. If nothing else you have a nice drain plug and a boss to add a temp gauge if you like. BTW, I do understand thermodynamics.

I have never seen results of any testing. People are only stating their theory's.

Looks like I may default to my original plan of purchasing an '08-'10 pan and filter.....might be a waste of money for essentially "bling"! Anyone here done the conversion i speak of? Since the newer pan comes with an internal filter is it necessary to use the bypass toilet paper roll filter in the front as well?
Thanks again

The new internal filter is a full flow filter. It is a good thing. I would still keep the external filter, but I have seen posts from folks saying you can leave the external element out of the housing after doing the mod.

So you are comparing your "I want this to be true" to my actual tests that show it is impossible to cool the fluid in the pan? The air around the pan is hotter than the pan, and the fluid doesn't flow around the pan surface very much, so if you understood thermodynamics you would know that the pan doesn't cool the fluid.
I know you want to believe it, but science is science. It is true whether you believe it or not.

Then you should be able to understand that the air around the pan is usually hotter than the pan temperature. If you understand thermodynamics you understand that air that is hotter than the pan CANNOT cool the ATF.
Get a job at Ford in Automatic Transmission Engineering. The data is stored there. The testing and the results belong to Ford. When I left it stayed there. I will not be posting them.

That sounds great guys......I searched on ed parts guy for the part numbers and found some , but Id like some clarification.....dont want to order the wrong stuff...any ideas on the 3 part numbers ('08 pan, filter and gasket) I need to order this stuff?
Thanks again Mark K for the engineering insight and thanks to all for their input

08 transmission pan 8C3Z-7A194-B
08 transmission pan filter 8C3Z-7A098-D
The gasket is re-usable

The air around the trans pan is NOT hotter than the pan on most of our trucks. You can say what you will about exhaust pipes and front air dams. Traveling 45-80mph on an average day in the US, the air across that pan is not hotter.
Its great that you worked with these trannys years ago. It really is. But maybe that's what is keeping YOU so hung up on thinking it is perfect in completely stock form. I preform development testing on turbine engines for a living, so yes, I do know a bit about thermodynamics. Nice how you throw in the higher temp statement while attempting belittle my knowledge. Nice try
If you have no proof of your testing we cant see the test conditions you speak of. So I'm going to tell you that I think you are wrong. I wont continue to argue with you about it.
Moving on now if you can keep it zipped shut???

Apparently I can't.
