Prior to torque converter installation, all diagnostic procedures must be followed. This is to prevent the unnecessary installation of new or remanufactured torque converters. Only after a complete diagnostic evaluation can the decision be made to install a new or remanufactured torque converter.

Begin with the normal diagnostic procedures as follows:

  1. Preliminary inspection
  2. Know and understand the customer concern
  3. Verify the concern - carry out the Torque Converter Clutch (TCC) Operation Test
  4. Carry out diagnostic procedures:
    • Run On-Board Diagnostic (OBD). Refer to DIAGNOSTICS .
      • Repair all non-transmission related DTCs first.
      • Repair all transmission DTCs.
      • Rerun OBD to verify repair.
      • Carry out Line Pressure Test. Refer to SPECIAL TESTING PROCEDURES .
      • Carry out Stall Speed Test. Refer to SPECIAL TESTING PROCEDURES .
      • Carry out diagnostic routines. Refer to DIAGNOSIS BY SYMPTOM .
      • Use the DIAGNOSIS BY SYMPTOM INDEX  to locate the appropriate routine that best describes the symptom(s). The routine will list all possible components that may cause or contribute to the symptom. Check each component listed, diagnose and repair as required, before installing a new torque converter.
