Well it looks like I got bite from being lazy. I figured that the pump rub fix was done when the trans was rebuilt, and now I have a leaking rear case. Has anyone tried to repair the cases by Tig weld it? I understand that the case is Magnesium, which I have never welded before, but for 25 bucks worth of filler rod, I would be willing to give it a shot. Anyone try this before and am I crazy for trying?
