Torque Converter Contamination Inspection

1. A new or remanufactured torque converter must be installed if one or more of the following statements is true:
   • A torque converter malfunction has been determined based on complete diagnostic procedures.
   • The torque converter stud or studs, impeller hub or bushing are damaged.
   • The torque converter exhibits external discoloration (due to overheating).
   • There is evidence of transmission assembly or fluid contamination due to the following transmission or converter failure modes.
     • Major metallic failure
     • Multiple clutch plates or band failures
     • Sufficient component wear which results in metallic contamination
     • Water or antifreeze contamination

2. If none of the above conditions are present, continue with the following fluid inspection.

3. Pour a small amount of transmission fluid from the torque converter onto an absorbent white tissue or through a paper filter.

4. Examine the fluid for contaminants, color and smell. The fluid must be free of contaminants, red in color and not have a burnt smell.

5. NOTICE: Do not use water-based cleaners or mineral spirits to clean or flush the torque converter or transmission damage will occur.

   If the fluid passed inspection:
   • drain the remaining fluid from the torque converter.
   • using only the recommended transmission fluid, add 1.9L (2 qt) of clean fluid into the converter and agitate by hand.
   • thoroughly drain the fluid.
