How To Troubleshoot a Ford Transmission Computer
- 1). Locate the open OBD port on the left side of the Ford's fuse panel in the driver's-side foot well.
- 2). Plug the OBD tool into the open port (there is only one that is large enough).
- 3). Turn the ignition to the "II" position and wait for the scan tool to retrieve the error code. This numeric code can then be used to determine what is wrong with your Ford's transmission. You will need your Ford vehicle's service manual to translate the code.
