Warning lights

You need a scan tool to retrieve the trouble code to understand what is causing the lindicator lights to flash.

What usually causes that?

The hold light flashes when the input or out put sensors go out on the transmission. Can you tell me if the speedometer is working? Also lets check the codes.
