727 No forward or reverse

The pump looks okay. No scores in the pocket and the gears look good. I agree with you on the converter. I grew up buying all our parts at NAPA. Unfortunately, the one where I live now seems to keep getting things wrong. They have given me wrong or bad parts multiple times. I bought the converter there. It was "rebuilt" by someone in town. Can a transmission shop test the convertor or pump? I have never had issues with one before. I will take your advice on pulling apart the valve body. One other factor. I rebuilt it around 5 years ago, it has been sitting with fluid in it since then without ever running. I don't know if this is causing an issue. I will replace the filter while it is out. Thanks again for your responses.
