NP241 seal and gasket (now with picture)

Does anyone know where I could find a rear seal (where the yoke goes in) for a NP241 t-case for a dodge? Also, the gasket between the main t-case housing and the a$$-end?

Thanks

I'm in desperate need of these, and yes, I did a search

there is no seal between the 2 parts of the case they are sealed with a RTV type sealant, the output shaft seal is (chicago rawhide part #18662) available at any parts store.

I am With Stupid There is no seal between the t-case and tranny mating surfaces. If you have fluid coming out of there, you have a rear tranny seal leaking.

Check the Dodge forum on my tranny write up...I showed how the tranny seal is replaced.

The output seal should be able to find at most any autoparts store.

Autozone was useless. Didn't have it.
What do you mean there is no gasket between the main housing and the rear end of a t-case? I was told I can't put silicone there cause ATF will eat through silicone.

MADD, are you talking about a transmission seal?

EDIT: I went and read that thread. I'm not talking about that. My tranny is solid. I need to make a gasket between the tranny and the extension housing, but other than that I'm good. All my real problems are on the transfer case.

If you guys say I should be able to find the output seal, I'll keep looking, but it's kinda hard when your neurologist says you can't drive for a few months...I'm epileptic, and I had two seizures in four months. Bang Head ROTFL

Go to carquest or napa and give them that part number, or let me know, I'll get you one (shipping would suck though).

first thing like madd said, tranny fluid should not be in that area anyway so theres no reason for it to eat through the silicon... if your getting fluid there you have to fix the other seals.

second there are sealants that work fine with transmission fluid, i use an orange stuff from the toyota dealership made for transaxles which works great.

You sure? All my friends say the transfer case needs ATF...but then again my friend Bobby said gearlube.

Ok, say I put ATF. I should be able to get away with silicone between the main t-case housing and the a$$end, right? SalvageExpert, it's the rearend you sent me. What, like 3 months ago? I'm still on it... ROTFL

You guys forced me to whip out Adobe Photoshop...don't worry, I'll leave any "talent" at home Thumbs Up!

the np241 is MADE TO RUN with ATF, gear lube can be used on extremely worn to cases to help keep them quite.

the adapter peice between the transmission and transfer case has no gasket available. never was a gasket even from the factory. it was sealed with silicone

the rear output housing has a gasket but i dont know where to find that, i use silicone on that as well.

and the output seal is available at advance auto, parts america and autozone. chicago rawhide #18662 or National seal #3946

Oops! My bad! I meant to put "say I put ATF." I fixed it. Sorry.

and ATF will not eat through silicone, right?

Autozone (at least the one near me) does not have the seal. They're useless. But the O'Reilly's does Thumbs Up! . So silicone between...
the tranny and extension,
the extension and t-case,
and the t-case and it's rearend?

And just go buy that seal, right?

yes but use a RTV sealant that is resistant to gasoline and solvents...

like i said i use an orange goo from the toyota dealer made for transaxles. i think permatex makes a good sealant that works the same but i forget what its called.
