I recently installed a b&m deep pan and kept having a leak I couldn't get sealed. I thought it could've been the pan so I was just gonna put the stock one back on. Then we noticed while on the lift the trans had a hairline crack coming from one of the bolt holes for the pan. Is there a way to fix this or will it just get worse over time and start causing worse problems?

 

This just didn't seem like a normal issue to me so any help would be appreciated. Trans is a 4l60e in 98z

 

We just discussed trans pans in this thread:

As mentioned, there have been reports of people hitting things with the extra-deep B&M pan and I would suspect this in your case too.

 

The crack isn't on the pan its on the trans itself coming out of one of the bolt holes. I haven't even drove it enough to hit anything bc of this issue

 

Oh, sorry. That sounds even worse then.
I have no knowledge of how to fix cracks in the case.

 

I don't even know how it would happen in the place its at. It's not a normal situation. I can't even drive the car without carrying extra transmission fluid with me anytime I take it out. It's a pain
