1993 U225 5.9 Cummins/643 Allison Speedometer Sensor

My speedometer sensor shows 1/2 speed (30mph at 60mph). I suspected it would go bad when I noticed the speedometer needle moving too much.

My mechanic friend lost the ability to work on vehicles after shoulder surgery so he can't help me.... and I am not sure what is plugged into the Allison 643. I can spot the gear change selector and that's it. But my abilities to crawl around under the coach have declined...

I'd call FT and ask them but I heard that they no longer give information to FT owners unless they are members of their special club.

So, barring that, does anyone have a clue where I can buy a new speedometer sensor?

Best,
