Yes, you will find that seal stuck in the case. Everyone here has mentioned that. You are the one that says the seal is part of the case. We are telling you that you are wrong. It is a part of the filter and this seal tends to stick in the case when you remove the filter. You must reach in and remove the seal before you install another new filter.
What don't you get? Are you that slow to understand that you are looking at the problem and coming up with the wrong answer.
The conversion has been answered by post 36. I'll challenge your belief on the seal when I find a yard that will allow me to flip an E4OD over and get a few images.
This is funny. It's not about 'BELIEF's.
There are facts, and then there is you that refuses to understand that aluminum is not orange.
This ain't my first rodeo with theE4OD. I've replaced gaskets, seals and filters in many. The pics when posted next week will show what I'm dealing with.
I think it is.
PS. by the way, if you use the clips on the filter, you have the wrong filter.
Sure, here is a single picture of two pumps, one has the seal in it (orange in color), the other picture is with the seal removed. Which the OP refuses to take out the old seal, and insists that it is part of the pump. Maybe the OP does believe in Unicorns, heck swimming unicorns exist, they are called Narwhals.
A couple years ago I did a ‘pan drop’ and fluid/filter replacement on our ‘95 F-53, the orange seal came out with the filter. This summer I did the ‘pan drop’ and fluid/filter replacement on my ‘91 F-350, this time that orange seal stayed stuck in transmission housing, 45 min later, after carefully digging it out, I able to continue on with the procedure. Sometimes those seals come out on their own, sometimes they don’t.

Thanks for posting this picture. I was starting to question my memory, but what you have shown is exactly when I recall.
I replace my ATF every ~60k miles or so and it runs ~150-175F, never had a seal stick. 378k miles and counting.
I repeat. Just because you haven't seen it or experienced it does not in any way mean it doesn't exist. Also, I'm not trolling anybody nor am I wasting time typing crap in this forum just to get your dander up. Simply put. There was an orange-colored coating on a collar or other fixture that is above where the rubber sleeve sits. It's not a seized gasket or an O-ring baked to the pump port. If you don't have any idea what I'm seeing, then ignore the thread.
Constructive criticism is fully accepted but calling me a liar or accusing me of making something up so you have something to jump on is a waste of time.
There is no extra seal listed in any ATSG manuals, FSM, or any other literature. Or any aftermarket pump upgrade kits I’ve seen. For all iterations / revisions of the E4OD.
Ps. When you dig it out, use a plastic pick / hook so you don’t score the surface of the bore, it won’t seal if you score it all up.
I’ve also had them stick inside the bore. Heat is an issue imo. Do you have a trans temp guage?

maybe the filter was changed out like 10 times, and half those times the seal stuck. So over time you got a stack of 5 or more seals all crammed up there welded together.
yup, that’s what it is, multiple seals, not just one.

That's exactly what it is. You don't have a "special/rare" pump, and even if you did, you wouldn't want it. Do you find it interesting, that what you're looking at matches the color of the filter o-ring perfectly? What do you suppose the odds of that are?
E4OD/4100 pumps are all over ebay. Take a look at good clean/reman pumps and you'll see the filter port is support to be clean.
