I missed that, but not all codes appear on some readers. My 300 read codes, with results on the dash not to be seen on my hand held code reader
I would not call it a phantom limp mode, it is limp mode. I had it on my 300 and it was touchy and then it just stayed in 2nd gear, making it a slow journey to the dealer as it was still under warranty. The 300 had the same basic transmission as the Crossfire.
