Leaking out of that hole. I cropped the photo but it still posted the og screenshot with my weight loss photo.

My man dbowen said there’s supposed to be a 1/2 npt drain plug there. Do the threads look 1/2”

No ideaJust some friendly teasing
what does that hole lead to?
@dbbowen is a smart man, run to the hardware store and pickup a 1/2 npt plug, see if it fits. Worst case you’re out $3
Paging @cruisermatt
To be completely honest, I learned this from @orangefj45 ... @BurntToast im just a dude who forgets to take his OCD meds pretty regularly
but youre supposed to drill that hole out to 23/32 and tap it with a 1/2 npt tap and use a pipe plug slathered in 00295-01281 orange FIPG (AKA Threebond TB1281). At least i think it was 1/2 npt. Its been a while since ive done one. I had to do the same thing in a NV4500 adapter too. I ran out to shoot a pic of my adapter. You can see my plug in that hole there. Its better to drill/tap from the inside so the metal shavings dont get into your fluid.
You could figure out what the threads are on that hole already and get a really short bolt and just plug it from the outside. Just use 00295-01281 orange FIPG (AKA Threebond TB1281) and it "should" be ok until you do your next t case rebuild.
What id be more concerned of is how much ATF is leaking out. You probably need a new 4l60e square type O ring seal that goes on the back of the trans where it mates up to the hex part of the adapter. And you could do well with applying a very liberal amount of 00295-01281 orange FIPG (AKA Threebond TB1281) to the splines of the spud shaft. You shouldnt be getting any ATF in your Tcase and your fluid shouldnt be red at all if you do the drill/tap and plug, o ring, and RTV the next time your Tcase is apart.

Yup. You need to tap that hole to 1/2” pipe and plug it.
Super simple “fix”.
