IF when you purchased your car you didn't set your own personal code you will have to take this to your local GM dealer and they can pull the code that is set at the factory and unlock your radio.THe proceedure for setting your own code then unlocking radio is in your owners manual.The dealership I worked for did this for free.

You need the trouble code (DTC) to troubleshoot exactly what's wrong - you can use a code reader to see this. If you have the road sensing suspension option, it's usually one of the four wheel vertical motion sensors, and if that's the problem, GM sells a replacement sensor kit that you should be able to install.

The TCC solenoid is located inside the transmission. Replacing the solenoid usually does not fix the problem when it comes to a P0741 code. It is usually due to debris getting caught in the TCC regulator valve or the tubine shaft seals being worn out. This usually results in a transmission overhaul.
