Diagnostic Strategy: Notes
NOTE:
Do not take short cuts or assume that critical checks or adjustments have already been made.
Troubleshooting an electronically-controlled automatic transmission is simplified by using the proven method of diagnosis. One of the most important things to remember is that there is a definite procedure to follow.
Follow the procedures as written to avoid missing critical components or steps.
To diagnose a concern correctly, the technician should have the following publications available:
- Technical Service Bulletins (TSBs).
- Wiring Diagram.
These publications provide the information required when diagnosing transmission concerns.
