The "open circuit" part of the second code and my concern that the two codes are related keeps making think it's an electrical problem with the actuator motor or resistor. I'm a civil engineer and barely passed circuits 101 so I'm always afraid of an electrical problem that I can't deal with myself. I did read about the resistor being matched to the TC at the factory and would prefer not to replace if it's not bad.

I do plan to support the TC and take off the cross member to get to the actuator. Do you know if that is a big hassle in case I need to get back to the actuator if the gear flip or gear replacement doesn't clear the code(s)?

Thanks again for the replies. If it's poor taste to reply all and not quote replies let me know. I'm new here.
