I just replaced the Transmission in my 2008 Outback Wagon. All codes were cleared but Now the Cruise Control light is Flashing and the Check Engine light is Solid. When I try to start the Car in the AM and I Press on Had pedal Cat had no Power at All. If I **** it off and reset Gas Cap it Starts up. I managed to get check engine light off for a Day as Well as the Cruise Control light but they are back on again and Car having trouble starting. Once I fiddle with Gas Cap I am able to get Car started. Is this a Gas Cap Issue? Do Codes need to be reset? They were after I put in new transmission? Can I reset codes myself by disconnecting Battery Positive Cable? So Confused.
