It's amazing.
We're talking about welding by argon?







How is this possible without removing the transmission?
Inside the transmission fluid, it will not allow to warm up the metal to the desired temperature. No right temperature - not the quality seam.
If you reheat the metal for a long time, then the liquid will boil and will be expanded. It will seek exit and find him, you can believe me. Where this will hit the boiling stream? In addition, high temperatures will likely damage the transmission stuffing.
Another aspect - fire safety. On the surface of aggregates of oil stains. Near the fuel lines and plastic parts. Hazardous work welding machine near flammable materials.
I can admit that welded "ears", fixing the transmission housing. Another option ... You can unscrew the pan, remove the filter, drain all fluid from the transmission. But the danger of overheating transmission stuffing remains.
Perhaps you can solder a small crack on the periphery with a soldering iron and a mixture of lead and tin, which is used by installers of radio.
However, argon! ..
Americans! You or virtuosos, or nihilists. And the first and second deserves respect.

 

Actually MIG welding would be preferable.
Low weld heat is one of the great benefits of using the pulsed MIG weld transfer mode on aluminum..

 

agree with you.
Low-temperature welding - a solution to most problems. except the wet walls of the crack.
But what is "MIG welding"? I search the web

 

MIG = metal inert gas

"MIG welding" - in Russian is called "Automat". But it's 3000 degrees Celsius and more!
In other matters, I will not argue. Sleeper, judging by your picture - you are an expert in this case. I believe your word.

 

"Expert" ? well those are big shoes to fill...

I'll just say I do some welding........

 

But it's you sitting on the left, and welding the motorcycle fork?
If this is you, then you know how to weld at least that - then.
I can imagine how the work Automat. Short pulses, is heated by a very small space for a short time. Thus, we can "close up" the gap in outside through the wire, as the patch. For a small - narrow! crack it was enough. But will not be able to brew a gap at full depth.

 

Just out of curiosity, did you have the trans fluid flushed, or just drained and refilled what came out?

 

no. I have not tried to set fire trans fluid. Not sure of its ability to burn.

 

Considering the total amount of miles on the vehicle, I believe I would have tried slightly widening the crack and using JB Weld. If it still leaked you're not out anything as the crack would have to be widened to do a proper weld repair regardless. JMO
