Anyone else here ever had any problems with cracking a stock powerglide case? Mine has developed a leak in the front, and I at first thought it was the pan but after closer inspection its about a half inch in front of the pan on the passenger side. I'm pulling it out tonight to see if I can have it Tig welded. Don't really want to buy a new one since this one works perfectly fine and has quite a bit of work done to it. Is it age or is it a common problem with these things?
