I was driving around last night when out of nowhere I noticed my truck felt like it was stuck in first gear... I plugged in my superchips amd I got this b2215 fcm internal code.. I disconnected my negative battery cable for a little bit to see if that would help but once I turned my lights on the issue came back.. I thought it was a short in my hid harness but I checked amd they are fine.. Any ideas what's wrong or how to fix it?? I have an 07 1500 5.7 if that helps..

Take it to the dealer, I think there are TSBs for this. Dealer will fix free.
