SECTION 307-01: Automatic Transaxle/Transmission — 6R80	2014 Mustang Workshop Manual
DIAGNOSIS AND TESTING	Procedure revision date: 01/07/2013

Diagnosis By Symptom

Diagnosis by Symptom gives the technician diagnostic information and direction, and suggests possible components using a symptom as a starting point. All routines start out with any potential electrical components that can cause or contribute to the symptom described. The routines then list all possible hydraulic or mechanical components that can cause or contribute the symptom described.

Diagnosis by Symptom Chart Directions

Using 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:
1. preliminary inspections.
1. verifications of condition.
1. checking the fluid levels.
1. 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 Routine 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, the vehicle may exhibit slightly firm, delayed or early shifts. This operation is considered normal and will not affect the function of the transmission. Normal operation returns once these parameters are stored by the PCM.
Begin Diagnosis by Symptom with the Routines, if indicated. Follow the reference or action required statements. Always perform the OBD tests as required. Never skip steps. Repair as required. If the concern is still present after electrical diagnosis, 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. Inspect all listed components to make sure that repairs are complete.
