P0717 Input/Turbine Speed Sensor Circuit No Signal
The system uses a reluctor wheel and a magnetic sensor to aide in shift patterns. If the sensor wiring, sensor or wheel inside the transmission become damaged, it can trigger this code. This should be looked at by a trusted transmission tech in your area. Cadillac does some wierd thing things when it comes to placement, wiring and repiar. Get someone who knows Cadillac to get this done for you. It will save you a lot of heart ache and cursing at the car. Hopefully it will just be a bad sensor, and you will be back out on the road in just a afternoon. Let me know if you need anything else or wish to tackle it yourself. I think I can find some instructions.
