hair line crack in transmission housing?

Crawling under the jeep today to find an exhaust leak I noticed this hairline crack in my trans case. Any need to be concerned? There's no leak at all. Any preventative maintenance I can do to ensure it doesn't start leaking, or is it about to bite the dust either way. Thank you guys for all your great help.

Auto, manual, where on the trans? No crack is good, but where?

I over tightened my fill bolt and cracked the housing on my ax5. I immediately threw the JB weld on there but it never worked. Crack kept growing. Although my 5th gear was going so it was a great excuse to do the ax15 conversion

Ugh, I'm not sure. Ax-15 I believe. It's actually in the bell housing. Close to where the transmission case and bell housing meets, on the bottom. I've got a clutch replacement coming up soon, hopefully itll hold up.

My brother in laws 79 mustang exploded the clutch
Broke a chunk out of the bell housing

He rode that car trouble free for about 10 more years till a hurricane flooded it

Its actually on the bottom of the bell housing. I saw the crack and panicked and posted before actually observing the issue. Sorry guys.

I'm going to mark it and see if it runs. Maybe see if I can get someone to put a weld on it. Is that a high heat/high pressure point?

If you decide to JB weld it, drill some dimples at both ends of the crack. That will stop it from running. Don't go all the way through, just a dimple with an 1/8" bit.

When I raced r/c cars I used to drill 1/8" holes at the ends of the cracks in the body
The hole would stop the cracks from
Spreading.

Now this was done in plastic but the same principle

Well, it ran to where the housing meets the transmission. Now its leaking there. Looks like I'm going to be spending a few bucks. Anyone know a good jeep mechanic in baton rouge?

I went and had a mechanic look over the crack to be safe. He said there's no fluid in the bell housing, its sealed from the transmission. All the bell housing is holding is my clutch. Does this sound right to y'all?

The bell housing's purpose is to adapt the transmission so it can bolt up to multiple engine types, consider its primary purpose to be an adapter. Its other purpose is to house the clutch mechanism. No lubricant is inside the bell housing itself.

no oil in the bell housing..you could have it welded now where it is but would probably get a better weld if you took it off and cleaned it good first and welded it flat rather than having to do it overhead
