Diagnosis By Symptom Chart Directions

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

Use the Symptom Chart to select the Concerns and Symptoms that best describes the condition.
Refer to the routine indicated in the DIAGNOSIS BY SYMPTOM CHART .
Always begin diagnosis of a symptom with:
- preliminary inspections.
- verification of conditions.
- checking transmission fluid levels.
- carrying out other test procedures as directed.
NOTE: Not all concerns and conditions with electrical components set a DTC. Be aware that the components listed may still be the cause. Verify correct function of these components prior to proceeding to the hydraulic/mechanical components listed.

NOTE: When the battery is disconnected or a new battery is installed, certain transmission operating parameters can be lost. The PCM must relearn these parameters. During this learning process, slightly firm shifts, delayed or early shifts may be experienced. This operation is considered normal and will not affect the function of the transmission. Normal operation will return once these parameters are stored by the PCM.

Follow the reference or action statements. Always carry out the On-Board Diagnostic (OBD) tests as necessary. Never skip steps. Repair as necessary. If the concern is still present after the electrical components have been diagnosed, proceed to the hydraulic/mechanical components listed.
The list contains only possible hydraulic or mechanical components that may cause or contribute to the concern. These components are listed in the removal sequence and by most probable cause. Inspect the components listed to make sure the repair is correct.
