These codes are generated by the car’s onboard computer (ECU) when it detects a malfunction or irregularity within the transmission. These codes, often displayed as a combination of letters and numbers, provide clues about the nature and location of the problem. Identifying these codes is the first step in efficiently addressing transmission issues.
