I have just bought a 4r75w used transmission case to replace mine. I cracked it so needs to be replaced. The used case i have has three holes towards the end of it. They are chips in it and was wondering if anything goes into those holes and if they are used. Any help with it would be more than helpful if you need pictures of it let me know. I can produce them.

 

Pics would be nice

 

I am hoping this will download the image for the problem. It is a straight shot toward the back of the transmission

 

Those holes are supposed to be in the cases, I admit yours look chipped but I don't see any issues with it.

Nothing goes in the holes.
