Code Reference Charts

NOTE: In addition to transmission fault codes, engine-related fault codes may be output during QUICK TEST procedure. These fault codes pertain to engine performance and must be repaired first as engine performance will greatly affect transmission operation. For information and testing procedures of engine-related fault codes and components, see appropriate TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section.

NOTE: Trouble code 676 indicates failure of low one-way clutch. Code 677 indicates failure of low intermediate band. For both codes, see TROUBLE SHOOTING procedures in the AUTO TRANS OVERHAUL - FORD AX4S TRANSAXLE article.
