We had two 727s to choose from. The one that was in it and a spare. The first one we filled up through the tube. Putting it in gear it felt like the brakes were locked up. They weren't. It would move but barely at higher rpms. We took it out and it felt like the torque converter wasn't full. We put the other one in, filled it up and it has a crack by the shifting mech. I researched brazing aluminum and it looks pretty easy with Hobart rods. Anybody have any good ideas?
