Liquid welds on the tranny case, JB Weld, Permatex Gear Oil RTV Gasket Maker, ?? Options

[Hank914]

I have a tranny case leak that needs a repair. Here is a pic of the leak, which when warmed up is about one large drop a second.




I figure that I should do a real weld for the permanent fix, but would like to do a temp fix so I can drive over to my welder brother-in law about a 100 miles away.

So, what is the best liquid weld goop for this type of a hole (about 1-2 mm in diameter)?

Every one of these solutions, except maybe drilling and tapping, requires a CLEAN surface wherever the glue will have to stick. That means removing EVERY trace of gear oil from the area involved. As the hole is on the bottom, that means pulling the gear cluster and cleaning the inside of the case, flushing the hole/crack with a good solvent, turning it upside down, and heating the area to "sweat" any remaining contaminant from the problem area. With the case still warm, apply the JB Weld or other appropriate epoxy to the affected area and give it 24 hours to dry. DO NOT use the quick cure stuff, as you sacrifice a good part of the effectiveness of the repair in exchange for the speedy cure time.

Edit: I would certainly try to determine the thickness of the affected area before I chose a tapered pipe plug. If it's as thin as I think it may be, there might not be enough metal to ensure a good seal.
