Check Emission + Transmission Sign

What is your question?

I have Acura RDX (2008) with 58K miles. Last night after filling the gas and draw few mile and "Check Emission" sign came. I stopped the car checked the gas cap and closed it again with three clicks. After driving few miles "Check Transmission" sign came up with "D" Blinking. I stopped the car and waited few minutes. Check transmission sign went away while "Check Emission" sign continued. This morning, "Check Transmission" sign with blinking "D" came again. I checked Transmission oil as recommend in the owners manual and looks good. Manual tells to take it to the dealership. Any suggestion before I head out to dealership?
