2001 T231 weep hole leak- tranny output or transfer input?

[bagpiper22]

I just replaced the gasket on my transmission pan, and once I filled it back up with fluid I started getting a leak from the transfer case weep hole.

Transfer case also has ATF-4 but wasn’t leaking until the tranny fluid went in.

Does that tell me it’s the transmission output seal, or could it be the Transfer case input seal? If the transfer case seal were bad wouldn’t that leak regardless of the tranny fluid level?

The skid plate is currently off, so I need to disconnect both driveshafts and drop the transfer case, correct? If it’s the transmission output seal, should I drain that first? Will the transmission fluid pour out once I pull the seal?

Found this great write up https://wranglertjforum.com/threads/how-to-replace-leaking-seal-between-32rh-transmission-and-transfer-case.13170/

Any other links to write ups or videos on this job are greatly appreciated!

Thanks for the help!

I don't know that there is a way to tell, but you have to remove the transfer case either way, and you'll probably be able to tell which one it is. I've never done the input seal on the t-case, but I don't think it requires any level of disassembly. I might be inclined to do both seals while I had it apart, but then again whenever I rebuild transmissions I don't ever touch the seals on the t-case. Maybe that's a miss on my part?

Don't forget to lube the seal & t-case input shaft when you mate them back up.

Also, I'm not sure if you'll need to drain the transmission; I'm not sure if the fluid level sits above the bottom of that seal or not. If you have a drain plug on your pan, it's probably worth it to drain the fluid. I'm cheap, so depending on how old that fluid is, I might catch it in a bucket and put it back in. ¯\_(ツ)_/¯

If you don't have a drain plug on your pan, this is your big chance to renew your fluid, replace the filter, use a lube locker gasket, and get the deep pan with the drain plug.

Yes I have a drain plug so I’ll do that. Easy enough. And yes, since the fluid is new I’ll catch it and reuse it. Thanks!
