Oil leak from the rear of the upper oil pan
About 6 months ago my wife nailed a rock and put a hole in the upper oil pan. When I replaced it i made a Bobo..lol. I left the two rear bolts in not knowing that they were there. While I tried to pull the upper pan off I managed to almost tear the bolts out. When I put it back together I tried to straighten it the best I could. I still have a leak and it is getting much worse now. Any suggestions on how to stop the leak without buying a new transmission. That is what the dealership said I needed to do. Any help would be great.. thank you everyone in advance.

I think the post is confusing in general....highlighted by the response above. You had a hole in your oil pan, went to take it off, jacked up 2 bolts, and now dealer is telling you you'd need a new transmission to fix it? LOL. I must be missing something. I think if re-explain it better, you might get more responses. Is the problem that you've jacked up 2 bolts on the oil pan? the threads are jacked so the bolts wont seal the pan properly? If that is the case, you've tried re-tapping the threads? If the problem is different, please elaborate.

The seal
When I originally took the upper pan off I be t the area the bolts go into. Since it is all cast aluminum I can not retread it or get it bent back in place. The part that it is bent is the bottom of the transmission. This is why they are saying to fix the problem I need a new transmission nousing. Sorry for the bad pictures. I hope this explains it better. I don't k ow how else to explain it since u don't know the proper part names.

The picture is mainly to just show where the bolts were. The lower pan bolt that is gone doesn't leak at all. But up in those 2 holes shown in the picture Is where I messed up. I didn't know there were bolts up there so I destroyed the area that the upper pan mounts to.

So the two bolts you damaged. Can you tighten them at all? If so, I would imagine removing the pan and using a little more RTV should seal things back up I would think.

You are referring to circled positions in the attached image, correct?
If so, can you drill and heli-coil the original holes?
Worst case scenario is drilling new mounting holes in the upper pan and transfer punching these into the transmission then drilling/tapping. It may be difficult to access these bolts though as I see current two have access pockets.
