How to Use This Section

This section provides the following information:

• General diagnosis information on transmissions
• Procedures for diagnosing the transmission

When you diagnose any condition of the transmission, begin with DIAGNOSTIC STARTING POINT - AUTOMATIC TRANSMISSION . This procedure indicates the proper path of diagnosing the transmission by describing the basic checks. This procedure will then refer you to the locations of specific checks. After you have determined the cause of a condition, refer to REPAIR INSTRUCTIONS  for repair procedures. If the faulty component is not serviceable without removing the transmission from the vehicle, refer to Unit Repair for repair information.
