Can a hairline crack in the transmission bell housing be repaired?

Hi,

It likely could be welded. However, it is aluminum, and you will need someone that can TIG weld. Please keep in mind that I'm not sure where it is leaking other than the lower left. Are you certain it is the bell housing and not a pan leak? I ask because it's odd that it would leak faster when running unless it is in a pressurized section.

Let me know.

Hi,

No problem whatsoever. The bell housing is what attaches to the engine. What you described sounds like the transmission housing.

It's interesting that it's worse when it runs because if it is at the fill port, the fluid is at its highest point with the engine off. When started, it drops to the fill port level.

Because of the location, it may need to be removed to have it tig welded. They make products that may help temporarily. Actually, it may last the life of the vehicle, but I can't be sure. Take a look at the pic below.

If you decided to use something like this (there are other brands), the area needing repair must be clean and dry. I would recommend using something like a brake cleaner to remove any oil and dirt from the transmission. If you have access and the area needs to be repaired and it's flat and smooth, take sandpaper and rough the area so it has a better chance to stick tightly.

Let me know your thoughts.

Take care and let me know if you have questions.

Hi,

It will certainly slow things down. I believe the resin can be porous and still allow it to seep. See what he thinks of the product I mentioned above.

All in all, the most important thing is to have the part for repair to be clean and dry so what you use has a chance to adhere properly.

Let me know.

Hi,

You are very welcome. If you get a chance, could you let me know how it turns out for you? I'm interested in knowing if that takes care of the issue.

Let me know. If you can't, I understand.

Take care,

Joe
