I have a 48 TE20 that was my grandfathers and we have dug it out and started working it on our deer lease. It has the aluminum trans case and has started corroding from the inside out. I?m looking into welding an aluminum patch over the entire bottom side. Has anyone else had this happen? What would cause this?
 
This will give you a little more info. I don't think it is aluminum or aluminium.

Welding to the Electron alloy is fraught with difficulty . One of the major problems is that in some circumstances it is prone to catching alight due to its high Magnesium content . Do you remember science classes and burning Magnesium ribbon ? It's much the same as that . TE20 tractors caught in bushfires here almost invariably have nothing but the engine, guards and rear transmission casing left , the rest does not melt but burns away .
 
If the corrosion isn't so deep as to weaken the case too badly I would probably repair it by pouring epoxy to build it up. It will need to be very clean for the epoxy to stick but then it won't corrode.
 
I'm more of a Ford guy,but if you don't care about originally, wouldn't a TO20 trans bolt up or try to find a good TE trans.
