I found Appliance Parts Pros while researching the drain pump. The videos accompanying the part search helped identifying what it would require to replace. Decided to change several other parts since I was gong to have disassemble the Washer quiet a bit in order to replace the pump. Replaced the pump, but also replaced the Door Gasket, pump hose, pump case, and filter assembly because of concerns with lingering odor in washer (even though the door is always left open). Glad I did as I did find slime and crud built up on walls and crevices of all previously ID'd parts. In all, it took about 3 hours to replace all the parts - the Videos were a great help and I used them as reference as needed throughout. I would estimate that I saved at least $500 on a service call.
