Trouble Code Definitions
NOTE:
Only transmission-related trouble codes are listed. For engine-related DTCs, see appropriate TESTS W/CODES
article in the ENGINE PERFORMANCE section. Engine-related DTCs must be repaired first, as engine performance and related component signals will affect transmission operation and diagnosis.
