Just a question, but doesn't the cable drive gear and cable still need to function to drive that device too??? If your tail shaft speedo drive gear isn't secured to the shaft and turning the cable drive gear, your signal box isn't going to provide any output to use.

Have you pulled the cable drive gear and looked at both gears to determine whats broke? Could be the driven gear that connects to the cable may have the teeth stripped and the main drive gear may be still intact.
