6.4 trans pan and filter on 6.0

[mcdaniel1991]

I cant seem to find much info in this. I have searched a bit, Im wondering if its worth it to buy the newer style pan and filter and stop using the toilet paper roll bypass filter? From what i see on FORD the service interval for this filter and fluid is 60k instead of 30k. Also i did read that with the newer filter all the fluid is filtered 100% of the time instead of just the bypass filter the 6.0s have up to a certain temp.

I think it's worth it.

the 6.0 converter is a 6 bolt style and the 6.4 converter is a 8 bolt style, there are some internal difference between the two also, the filter is different I believe and the trans pan on the 6.4 is slightly different too.

you cant post your website, you are not a sponsor

What does this have to do with the OPs question?

Yes..... that's the point. The new style pan and filter are better...hince why I would want to upgrade. I already know they work on the 6.0 just curious if it's worth the cost.

This!

Henri Paul in for the 1st post fail


I did the late 08 pan swap and instead of using the late model pan to accommodate the new style filter I used the Derale pan with the OEM reusable gasket I left the toilet paper one in place and made a label for it noting the new style filter in the pan
incase I ever sold it or got to old to remember LOL

i like having the better filtration all the time that the new style provides

Damn that is a deep pan! http://www.ebay.com/itm/New-Derale-...r_Truck_Parts_Accessories&hash=item3cd97edada

I think im just going to go with the stock 6.4 pan. I can get it for $60 but that^ is a nice pan.

Amazon had the Derale fir 130 ish IIRC

definitely not needed
I am in agreement with the school of thought that more fluid is better

not all agree but I am not open to discussion LOL

if the new pan does not come with a Gasket just use your old one it has crush prevention inserts and is OEM approved as reusable

Well it makes sense that more fluid would dissipate heat better/quicker then less fluid..:swordfight:

Can you educate me on that? I don't understand how more fluid will help dissipate heat better. I don't remember anything like that when I studied thermodynamics.

 

[mcdaniel1991]

No I can't...I didn't study thermodynamics. It just seems logical to my untrained brain.

More fluid will simply take longer to heat up and longer to cool down. I think the main benefit is that you will have a lower concentration of contamination with more fluid.

usually by adding more fluid, you're putting on a (larger) aftermarket pan which in theory would give you more surface area to help dissipate heat from the fluid? I could be totally wrong, I'm not an expert, just strikes me as logical.

That makes sense.

It makes sense until you understand how the whole system works. Then it falls apart because it is only wishful thinking, it doesn't work in actual practice.

The main thing that keeps a pan from dissipating heat is that there is very little fluid movement near the inside surface of the pan. In fluid dynamics it's called a boundary layer. This is a layer of fluid that just stays in place. It acts as an insulator. That fluid will cool off some, but not very much. It keeps the really hot fluid from hitting the pan so it can't ever cool.

The other thing that keeps the pan from dissipating heat is the hot air all around the pan. Have you ever measured the air temperature around the pan? I have. It's hot. You have the hot air coming from the engine compartment, including the air that has passed through the radiator. Plus the exhaust is nearby radiating a lot of heat. When the air all around the pan is hot, how will that cool the pan? The answer is that it can't. If you want to cool the ATF get a better cooler. The pan is not the way to do it.

Noted. Sometimes I feel like psa should be paying you Mark.

Sounds good to me!

 

[Zmann]

I know I said I wouldn't debate the larger pan / more fluid theories but this is different LOL

Mark's boundry layer is the best explanation I have ever heard IMHO

interesting the Derale pan puts tubes through the pan I wonder how well these work

at skirting the "boundary layer "

but I agree I wouldn't add an expensive pan and count on a noticeable cooling benefit
however moving down the road at a decent speed I would expect the airflow around the pan to be a lower temp than the internal fluid temps that may all change when you hit a steep grade and are towing ?

It won't make any difference on the boundary layer. And it won't make any difference on the hot air all around the pan.

Remember what I said about wishful thinking?

On the other hand, it doesn't cost me anything if you buy one of these pans.

Thanks for the info. Thats why i ask my questions here:toast:
