Why is my D4 light flashing

Hello, my name is Dennis O'Malley. I was hoping you could answer my question about my 02" Accord. Now I dont know why but my check engine light came on and then my D4 light started flashing then it caused my car to start running funny and was hoping you could explain.

Answer this question I have this problem too

Is this a good question?

The D4 light flashing means the engine computer detected a transmission problem. Stop by a parts store like autozone and have them read the codes. You should end up with a code that starts with a "P" and this particular model year had a TCM issue
