I cracked my tranny case once on the bottom kinda by the filler screw and i put jb weld over it and it fixed for like a month and then again it happened but it seemed like it blew a hole out, the transmision was rebuilt 3,000 miles ago so i took it back to the place and they said it was just a stress crack because i just put a type r motor in my integra but when i ask other mechanics they say the tranny is junk. What should i do replace the tranny or just try replacing the case, thanks
