Torque converter Trouble

I have repeated this time and time again and no body seems to listen or follow my advice. So once again. Look in the pump and u will see the two tangs. Turn them to the 12 and 6 o’clock positions with a small screw driver. What this does is Center the pump so the converter can slip right in. The pump gears are on an eccentric so if any other position u have great difficulty installing the converter. There is a trick for the flexplate to converter match up also. There is a tiny hole about an eight inch just below the bolt circle where the flexplate bolts to the crank. Line up the drain plug with it then ur converter will bolt right up or maybe I’m wrong there and it is opposite the drain plug. Kim
