Transmission light flashed

Hello, I am Danny.

That might mean you have a transmission code being stored. If you do not have access to a scan tool/code reader many of your local auto parts stores (O'Reilly's,Pep Boys, Autozone) will read the codes for free.If you have this done retain the printed read out of the code number(s) and get back to us. We will be happy to decipher the codes and let you know what is happening. I have attached a code read tutorial for you to look at. Hope this helps and feel free to ask any other questions if needed. Thanks for using 2CarPros.
