speed sensor
 

Thanks for the info Aredubjay, just what I needed to know.

Starship. There's a much better description in section 3-2, Page 74 of the manuals.

Vehicle Speed Sensor #1:
Mounted to the transmission extension case (from the outside of the case).

Its to the rear of the transmission, passenger's side (if you're not RHD).

Vehicle Speed Sensor #2:
Mounted to the torque converter case (from the outside of the case).

It's on the passenger's side (again, if you're not RHD) near where the tranny bolts up to the engine.

Took me a while, but I found it. I love "treasure hunts." :D (Hasn't FHI ever heard of an "index?" Geez!)
