Diagnosing an electronically controlled automatic transmission is simplified by using the following
procedures. One of the most important things to remember is that there is a definite procedure to
follow. DO NOT TAKE SHORT CUTS OR ASSUME THAT CRITICAL CHECKS OR ADJUSTMENTS
HAVE ALREADY BEEN MADE. Follow the procedures as written to avoid missing critical components
or steps. By following the diagnostic sequence, the technician will be able to diagnose and repair the
concern the first time.
