TCM failure codes refer to diagnostic trouble codes (DTCs) related to the Transmission Control Module (TCM) in a vehicle. These codes indicate malfunctions or issues within the transmission system, which can affect shifting performance, fuel efficiency, and overall drivability. When a TCM failure code is triggered, it often requires diagnostic tools to read the code, followed by troubleshooting to identify and address the underlying problem.

Most likely: 1) You are wrong and it is in second gear and you are driving a Chrysler.If so, you probably have a TCM code (often caused by a bad VSS or OSS or solenoid pack) or a bad TCM putting the trans into limp-in mode.To fix this, verify that you can use a scan tool to communicate with the TCM. If not, diagnose for communication bus problem or inoperative TCM. If Communication is fine, read codes, diagnose, then correct and then clear codes.
Both codes indicate a problem within the Transmission Control Module or TCM. Take it to a transmission shop, they can pull any additional code from the TCM.
