IIRC from another thread, you've already had this together and running, right? I'm hoping you didn't force the mounting of the trans-to-block using the bolts. If that was the case, the pump has most likely been trashed. When installing the converter into the trans, there should be 3 distinct "clicks", and with each, there should be some notable rearward movement. For a quick test, you can measure the distance from the block face to the outer edge of the flexplate and subtract that from the distance from the trans mounting face to the converter pads. This should give you 1/8" to 3/16". If the 1st dimension is more that the 2nd, your converter is not seated correctly.
