2005 Chevrolet Cobalt P0700 and P0717 Transmission Codes: What Do They Mean and How Serious Are They?
I recently had my check engine light come on after an oil change, and the OBD2 scanner revealed two transmission-related fault codes: P0700 and P0717. I'm looking for input from mechanics or transmission specialists—how serious are these codes when combined? What do they typically indicate, and what steps should I take to diagnose and fix them?
P0700 is a generic code indicating a transmission control issue or that the transmission warning light has been activated. P0717 specifically points to a problem with the transmission input speed sensor—this could be due to a loose or disconnected sensor wire.
