Where in the world can I buy or does anyone have a fix for a speedo cable leaking where it screws into the transmission on a 72 automatic transmission

Thank you

I bought the seal from Nissan, p/n 32709-14600 if that's the one you need. Mine is a manual but the speedo housing should be the same. There's some more info in this thread.

Here's some for sale...

From the thread, "That little Top Hat in the pictures only comes with a new Speedo cable.

However all is not lost. It is just a secondary seal. You can go to home depot and get a flat rubber washer that will do the same thing.  They come in various sizes and have approx a 1/8" dia inner hole." @Chickenman

Chances are it’s leaking on the speedometer housing itself. It’s been a minute but if it’s like the manual transmission there’s an O’ring and a seal like @siteunseen mentioned.

I really don't know about auto transmissions but seems like my auto Camaro I had to check hot and in gear with the E-brake on if I'm not mistaken. Have you recently put fluid in? Could just be slight over fill? Good luck with it no matter what.
