The thing must have flexed just enough and the converter hub spun across the top of the pump gear. I have also seen the turbine spline break a weld inside the torque converter. The first thing I would check is to see if the pump is pumping fluid. You could just take out the pressure plug on the drivers side or break a cooler line. If you have good pressure, the problem is the converter and the transmission is probably OK. If there is no pressure, the pump is damaged and will need to be repaired. One other thought; If you are using front mounts on your engine, you may want to change to a center mount on the engine because with the 200-4R it makes a real long span between mounts. These vehicles originally had bell housing mounts on the transmission. If you are using a mid plate mount between the engine & transmission, make sure you don't have too much space between the flex plate & converter.
