sorry I can't give exact vehicle info, probably early 2000's F-150 rwd.

Here is the used trans my coworker was about to install; [trans]

here is the weird crack I noticed; [trans crack]

(so he swapped tail housings).

I saw in a youtube video that these are prone to cracking down by the mount, if the truck lives in the rust belt, but this odd crack looks like porosity/defect to me, and is on top.

Just sharing....aloha!
