Default Speedo cable leak at turbo 350

I have a tranny fluid leak at the speedo cable where it threads into the tranny, does this have a o ring some place that may need replaced.The connection where the cable goes into the tranny is tight i cant think of what the fix is.Please advise as to who has been there done that, many thanks for the help.

Remove the speedometer gear housing (bullet) and there should be an o-ring on the outside ,pull the gear out and there may be another inside.
Replacing both should cure the leak.

there is a small bolt and a kinda metal retainer tab that hold the speedo bullet in the tranny (the end of the cable with the speedo drive gear). ther eis an o ring on that bullet. it will leak if that o ring is bad.

There's a little seal inside of that gear drive housing, those will make a nice mess if they need to be replaced. My 70 Monte was leaking there, couldn't find the right seal so I bought the whole assembly from the dealer. It comes with a seal in it, no more leaks.
