it looks like its time for a tranny flush or change

Well, you have an issue. I wouldn't say that it is the GMS, but it could be. The issues you are seeing could also come from low fuel pressure caused by a number of things from the little filter in the high pressure regulator to issues with the low pressure regulator. The frequency (HZ) thing is a little confusing---all it is saying is that the GMS isn't seeing the amount of requested fuel (requested by the AF ECU) passing through the sensor. If you have a mechanic that can scan the AF ECU, then the thing you want to look at is the requested gas flow v.s. the flow reported by the GMS. These two numbers should track each other. Sometimes the car sets a low frequency code when first trying to start as there just isn't enough NG arriving at the GMS during cranking. In any event, two things. Usually the GMS doesn't cure itself--so if it is running OK one day and not the next--it may be a fuel pressure issue. If you have, or can get a copy of the service manual supplement for any CNG Cavalier from 1999 through 2002, the procedures for checking fuel pressures can be used for your car. It is important to check the intermediate fuel pressures (at the entrance to the low pressure regulator) with the car under load. Also, follow the flow charts in the manual for diagnosis of the codes you received.

I'm sorry to say you will not find an answer online for this.As a mechanic I would have to be there in person, and the problem would have to be happening for me to track down the cause.I will say I did not understand your statement about the gears behind the dash, what you described sounded like a wiring problem or something in one of the electrical components.If the check engine light or the ABS light came on while the engine was running, you could have trouble codes stored in the computer. So it may be worth a visit to a shop or auto parts store to get the computer scanned. The codes would give you a direction to look in.
