Rallysnake/Jarendall/anyone else..

I Took out the speedo cable again today. Existing black 20 tooth gear o.d was the same dimensionally as the new ones I purchased. However, I greased eveything up real well including the reverse mechanisim on the speedo, put on the new gear and carefully re-ran the cable.
No luck..Still not working.

I tried runnning the speedo with an electric drill from the trans end and it worked very well with no jumping or any other abnormal behavior.

I took off the speedo end of the cable and the cable turns while the other end is in the trans. This can't be right. Should be locked.

Ran the car with speedo end off and trans end connected into trans and found cable does not rotate inside sheath at speedo end.

I also reconnected the cable and ran it with the rear wheels still off the ground just to cover all bases. Still nothing.

Either the Tremec uses a special speedo gear or somthing is not engaging in the trans, although the speedo did work for the first 150 miles when I got the car.

Some more confusion also because John's Mustang shows 2 different gears depending on the year of the trans and my rear ratio (3.55) 23 teeth(white) for 90-98 trans or 20 teeth (black) for 83-89 trans with 3.55 rear.

The 23 tooth would be a little bigger in diameter. Maybe thats it?If I tried the 23 tooth might I damage anything further?

How does one know which trans year he actually has? (I was assuming 83-89 because the gear that was in the car was black and Rockland originally told me last time I called the trans was a 83-93 version)

Going to call Rockland Standard Gear again tommorow to try to get some solid tech. support.

Any other ideas from anyone would be appreciated before I go crazy and pull the trans for repair..Thanks ...getting desperate....ox_ford_guy
