2004 Rancher Code 12 help…

I just got this machine and has a few issues, First was giving code 6, replaced the angle sensor as per the manual and that code went away. Unfortunatly it was replaced with Code 12, I have followed the manual troubleshooting for the shift motor and have ended up with the replace ECU solution. The motor runs very smooth when tested on the bench, The wires to the motor from the ECU check out just fine. The bike is stuck in limp. I never get an N D or R in the display, goes right to blinking code 12. Any Ideas?
