Its a brand new motor that just arrived an hour before i stuck it in. To be honest i just heard it running. I didnt really pay too much attention to how it was running. (my cooling fan is wired up directly so i cant really hear over the noise of it.) but when i tried it using a 12v supply on it worked perfect.When you initialized it did the control motor sound smooth when it cycled or kind of rough? Code 11 is for the shift control motor circuit. If the motor is dirty on the inside initializing it will "clean" it just enough for it to work for a while and then give problems again.
