This means there is a general error in the system. The only way you are going to be able to diagnose the problem is pulling the codes from the system. Most of the parts stores can use the code readers to pull the codes from the system for free. I would start with having them pull the codes from the computer so we can find out exactly what is throwing the error code.
I was really hoping to get a code that way I could pinpoint closer to the problem. The Error G means there is a fault in the gearbox. If the system is detecting anything abnormal in the shifting or one of the sensors it will throw out the error. Sometimes if you have a good enough code reader it will give the codes.
You can disconnect the battery for five minutes and touch the cables together than reconnect. But if the codes come back you will need a good enough handheld to scan the codes. It can be wiring issue sensor. I would look around for any damage to the connectors making sure they are good and tight.
They go to the transmission. I will try to look up some pictures tonight.
