Diagnosis by Symptom Chart Directions
WARNING: This page is about a different car, the 2008 Lincoln Navigator L and 2008 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
- Using the Diagnosis by Symptom, select the condition that best describes the condition.
- Refer to the routine indicated in the Diagnosis by Symptom Index.
- Always begin diagnosis of a symptom with:
- Preliminary inspections.
- Verifications of condition.
- Checking the fluid levels.
- Carrying out other test procedures as directed.
- Begin with the Routines, if indicated. Follow the reference or action required statements. Always carry out the on-board diagnostic tests as required. Never skip steps. Repair as required. If the concern is still present after electrical diagnosis, then proceed to the Hydraulic/Mechanical Routine 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. All components listed must be inspected to make sure that repairs are complete.
NOTE:
Not all concerns and conditions with electrical components will 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 Routine listed.
NOTE:
When the battery is disconnected or a new battery is installed, certain transmission operating parameters can be lost. The transmission control module (TCM) must relearn these parameters. During this learning process, you may experience slightly firm shifts, delayed or early shifts. 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 TCM.
