Transmission light came and "d" blinking but when I hooked computer to check code. Says "passed no code found" any one know what's wrong? I have tsx 06 automatic.

 

You might want to post in the 1G Section. This section is for the 2G TSX.

Anywho, you might want to start with checking your transmission's fluid level.

 

Standard OBDII code readers will read standard engine codes. I don't think transmission codes are includes in the OBD specs. In my old civics and accords, I was able to jump a couple of connectors to make the light blink the code. You need to check the service manual for your car. (Easier is to take it to the dealer to have the codes retrieved).

 

So I'm going to bump this thread as I have a 09 TSX with 140k on it and a new Flashing 'D' on the dash.

The car drives/shifts fine so I'm thinking its sensor related. I have an OBD II reader but no luck pulling the codes. I really do not want to pay dealer diagnostic fees just to see what the codes are.

Does anyone know or can anyone help me figure out how I may go about pulling my own codes?

Thanks in advance for any advice
