Hello, the only code definition that seems to be coming up is "Secondary Air Injection system air flow/pressure sensor circuit Low (Bank 2). Are you using just a basic OBD 2 scan tool that only reads engine trouble codes? There might be a different code stored in another module if you can do a full system scan. I dont think the secondary air injection would cause a transmission or transfer case issues. Ill take a look for any technical bulletins or recalls. But are you getting any code definition on your scan tool?
