I have some issues on my 06 limited. Scanner gives transmission control low voltage code, engine light comes on then driving for a while during a good rain it goes out comes back on after a few days. Some weird vibration comes and goes, sometimes, along with that. I bought a used PCM from a seller on ebay. Salvage yard I think but don't know. They did ask for VIN, Mileage, existing PCM p/n. I'm wondering is there any risk to swapping the ebay one with my current one? Anything I need to be aware of? I doubt there would be any risk but am looking for any tips etc.
