94 2.3L, 5 speed. Checking out the truck during an oil change; I discovered ATF on the Speedo connection to the Transmission. There also an electrical connector right next to speedo connector, which I'm not sure what it's for. What could be the cause of ATF coming from this connection and a possible fix?

 

1994 was last year for speedo cables, the part with wires is the VSS sensor used by computer and Cruise control, they are the same part/unit, speedo cable and wires

Looks like this if you pull it out: https://www.therangerstation.com/tec...s_withgear.JPG

There is a Rubber O-ring that seals the hole and it may need to be replaced, you can see it in both pics
Probably need to hit parts store with unit in hand to find a matching size O-ring

 

Thank you, Ron. I'll check out that O-ring, that makes sense to me!
