What is leaking?

[thatryan]

Hey all! So I have a 1967 C20 to work on, may even get to buy it

 

I believe it has a turbo 400 trans in it, and wondering if there is a notorious leak spot? Definitely good drip, but underside is so filthy hard to pinpoint, thought I would check before I go to power wash the underside ha.

 

Some pics, if helps...thank you!

You wanted to know "notorious" leak spots...................

My son has a '69 with the same problem....not sure what he's gonna do though.Like you said clean it up and run it to see where the leak is.

Sometimes the seals will quit leaking by just driving it once in while.

So its definitely the speedo gear and housing. Pulled it out tonight finally, seals destroyed, housing has crack, yeah. Initially I brake-cleaned the whole area, then saw drips forming out of the cable lol.

 

Now, where the heck can I find a complete assembly? Housing, gear, and all o-rings/seals. LMC and rockauto have nothing that I can find.

 

I know it is 45 tooth gear, and housing is labeled 40,41,42, and 43.

 

Thank you!
