Thanks for the Part Numbers and Vid I bet you were needen a smoke around 5:16 in the video Huh

 

Do you still run the toilet paper as well?

2006 F350 4X4

 

I put one back in when I did my swap -- only because I had bought a couple b4 deciding to do the upgrade. Mark K. says it is optional as the internal filter does such a good job. So when I run out of TP filters I'll leave the canister empty.

I don't know if I have this right: IIRC the earliest '08s had the external filter moved to right near the trans and "might" have also had the new internal one too. But the external one quickly went away and all the newer trans have only the internal...

 

I updated the original post with current prices from Autonation Whitebearlake Ford. You can get the filter cheaper elsewhere.

 

TKS--good to know.

 

The newer internal filter is slightly better than the external filter. I forget the micron ratings, it's been too long. The external filter only sees 10% of what's going through the coolers, and when the trans is below about 165F the flow to the coolers is cut by 90%. So once you have the newer internal filter there isn't a need for the external filter.

The external filter went away the at the same time the internal filter was upgraded. It was an either/or, they never ran both.

 

That might bring questions about the E4OD as well I would think.

The Derale pan appears to hold more fluid over the OEM pans..........
Would it also be possible to use the FT-180 filter in an E4OD to preclude using an external filter too?

 

The Derale pan does hold more fluid. The thing I don't understand is why you would want more fluid. I don't see any benefit. And I flat out don't believe the pan will lower fluid temperatures.

 

If he installs the 6.0 trans cooler in at the same time it might!!! Yes, I am joking around. But it IS much better than the one in the 7.3's.

 

Ok but excuse my ignorance. Why are we changing a perfectly good oil pan? Does my 06' F250 have an internal transmission filter? I just thought there was just the one on the frame? Bruce

 

I fixed the typo..
Short answers.. the 08 internal filter filters all the trans fluid. The 'toilet paper' external filter only gets a small % of the fluid.
Ford decided to upgrade to the internal filters in '08 - THAT should say something..
This will provide all the reasons..

Yes and in that thread, skip pages 3 - 6 as it gets ugly for no real good reason -- the pertinent info starts again on page 7...

 

There is some benefit in having a "lot" of fluid in that the more mass you have to heat, (and cool) the smaller and slower the temp excursions will be.

The downside is too much fluid would take longer (or too long for normal driving) to heat to normal/optimum operating temp.

The pan *could* be a heat exchanger in and of itself, but I think it would either need more "tubes" and forced air through them, and/or cooling fins on the bottom.

It would be easy to calculate the area and size of the fins needed to be effective, but it's unlikely the area of the bottom of the pan is large enough to be a "stand alone" heat exchanger.

And it's hanging down in an area where it could get "whacked"! Not a really good place to place a heat exchanger for a critical component.....

And has anyone considered that the air around the trans pan is HOT? You can't cool the trans with hot air, cooling fins tubes or not.

 

Wouldn't either one work like a radiator? Where the air hitting it is usually fresh.
