Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The code C1201 means there is a code in the engine control system so the code to address first would be the P2757. This code indicates a problem with the Torque Converter Clutch Pressure Control Solenoid Performance (Shift Solenoid Valve SLU). I have enclosed the test steps for this code in the link below, copy and paste the link to your Browser to open and view it.https://dl.dropboxusercontent.com/u/104923897/P2757%20Jan%206.pdf
You may have a bad ECM but that codes indicate other wise. I guess you will find out once you have changed it .
I am not sure at this point but because you have fault codes I would address them first starting with the test steps I sent you.
Not a problem, Im here when you ready. Post back if needed.
Unfortunately due to site policy new topics have to be addressed in a new post. If you want to open a new post we can work from there on the gear box concern. Be sure to list it in the transmission section.
Thank you as well.
