Hello guys -
I just bought a 1994 Quigley E350 with 278K on it and it sometimes "hunts" for the right gear so I thought I'd change the tranny filter and fluid. It has the 351 so I believe it has the 4eod transmission. After removing the pan and the filter, I noticed that the new filter wasn't quite the same as the new filter. The old filter didn't have the orange "seal" on it like the new filter did. Also, the old filter was a bit thicker than the new filter (the new filter has some "stand-offs" on it.
When I tried to put the new filter in place, it wouldn't easily go up into the tranny. I tried a couple of times and then looked up into where the filter plugs in. I noticed that there was a "seal" (orange) in the hole but it looked damaged a bit (I am assuming from my trying to shove up the new filter) - there were basically little pieces of the "seal" tearing off so I thought I'd remove them before they get torn off and sucked into the tranny.
My questions are - Do I have a 4eod? Can the "seal" that is in the filter hole (where the filter goes in) be replaced? Or did I just cause my self a tranny rebuild? Why are the filters different?
Just being original its just stuck. Pick it out and clean the surfaces of any bits and pieces and install the new filter. Look up the fluid change on the forums. Takes about 18-20 qts.
You MUST remove the old seal or you will cause yourself a rebuild. Right now you don't have a problem, that old seal will be one if you don't get it out.
If you drained the torque converter along with the pan you will need 16-18 quarts. If you didn't drain the torque converter you will need 6-8 quarts.

Thanks, I'll look that up. I'm not sure if its original, but I'll try to pick it out.
Thanks again!

Thanks Mark for the confirmation of the E4OD. I haven't drained the torque converter yet, but I may as well at this point since it's out of service until I get the seal dug out.
I've dealt with this same issue on a 4R70W tranmission---liked to give me fits! This image shows you're almost there getting the old seal out---look to the area circled in green:
Using something like an thing awl gently insert the tip between the seal and the case, carefully try collapsing the seal towards its opening and it should pretty much fall out.
Once its out you'll see there is an upper ridge or lip the seal fits up against to prevent it from being pushed into the transmission.

Hope this helps!
Thanks for the added info, it does help, because I remember the ridge and I thought it was a race or something that was pressed in. Now, I know what that is for.
Also, I looked at the Post about changing the filter and it talked about an o-ring, so far I haven't seen an o-ring, do all transmissions have o-rings for the filters?
Thanks!
Hello guys - Something doesn't seem quite right. I've tried getting the "seal" out and I had to "pick" it out with a few different pick tools. Does someone make a "permanent/lifetime" seal? It looks like the seal was wrapped around a metal "ring" (for lack of a better term). Does anyone know how/if I can clean the remaining seal off and/or remove the metal "ring" that seems to have the seal attached? Or does the filter seal due to the temps just get "glued" to the metal "ring"? Seal attached to "metal ring"?

Reason: Added info/question
The seal stuck inside the case should be pretty much the same as what comes on the new filter. Since the seal is supported internally by the filter's tube and externally by the transmission case there'd be no need for a metal ring or case.
Its not much consolation but those seals can degrade and almost fuse themselves to the case--persistence and patience might be required to fully remove it before installing the replacement filter. Sorry you're having so much trouble--been there, done that sad to say.
Thanks for the reply! It just seems like a horrible design to have it such that it can/does fuse to the case and does not stay on the filter. I do a lot of work on my own vehicles but this is the first time doing any transmission work.
If I would change it sooner is the likely hood that it won't fuse better?

4eod transmission filter?
