TROUBLE CODE DEFINITIONS
Note. Only transmission-related trouble codes are listed. For engine-related DTCs, see appropriate TESTS W/CODES article in ENGINE PERFORMANCE section. Engine-related DTCs must be repaired first, as engine performance and related component signals will affect transmission operation and diagnosis.
