Transmission / Overdrive: Speedomter cable hook up

[Keithsmcc]

Happy New Year to all. Hope someone can help me figure out what I have, or what I have to do to correct the problem. I have what is supposed to be the right speedometer cable and pinion gear, but they wont fit into the transmission. Any thoughts.

Looks like someone put a plug in the hole, perhaps when the transmission was rebuilt/painted?

[Keithsmcc]

Yes there is a plug in there, but the overall size is too small. The pinion gear won't even begin to go into the hole due to size, and the speedometer cable end just barley fits in there. Guess I should have mentioned the vehicle is 1960 Lark with a V8, and Flight o matic transmission.

Have you pulled the plug out?

Have you pulled the plug out?

No I have not. The plug is aprox 1/2 dia. the pinion gear closer to 5/8., and only the tip of the speedometer cable fits into the hole not even getting close to the o-ring to seal it. I received this Lark from a good friend who passed away estate. He did most of the chassis work I had the body work done. Got most of the vehicle in boxes.

Perhaps you are not understanding us. What you are seeing there on the trans is some manner of plastic plug that is merely stuck into the hole in the casting. Pry it out. Fling it far away in disgust. With a flashlight you will even be able to see the gear that the speedo pinion meshes with. Insert your speedometer cable and pinion; they are the correct size. Move onto the next task.

Hi Keith, I would have to see a side view of the Trans. end of that Cable you bought, to tell if you got the Old Style Cable that uses a Cork Gasket or the New Style that uses a Larger "Bullet shaped End" with Rubber "O" Ring.

I believe it changed in 1958.

Did ask told and .....the whole thing was a plug. I have now moved on to next task.
