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 am sorry. I need the seal for that Speedo cable attaches to the Automatic transmission

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...

The seal I need is like the seal on the right

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

Great. Thank you

The speedometer cables are the same. If you don’t know or haven’t heard, Go to “CarPartsManual.com”.

Thanks for that. I will.

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.

Here are a few pics that are puzzling. The connection of the speedometer cable looks dry. The cable has a drip on it and the floor show fluid.

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.
