NOTE:
Only transmission-related trouble codes are listed. For engine-related DTC definitions, see TROUBLE CODE DEFINITIONS in appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. For engine-related DTC diagnosis, see BASIC TESTING article in the ENGINE PERFORMANCE. These DTCs pertain to engine performance and must be repaired first, as engine performance and related component signals will affect transmission operation and diagnosis.
