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.
^
Converter rivets, impeller hub or bushing are damaged.
^
Discoloration (due to overheating).
^
Evidence of transmission assembly or fluid contamination due to the following transmission or converter failure modes:
-
Major metallic failure.
-
Multiple clutches or clutch plate failures.
-
Sufficient component wear which results in metallic contamination.
-
Internal torque converter contamination present.
Torque Converter Contamination Inspection
Torque Converter Contamination Inspection
CAUTION: Do not use water-based cleaners or mineral spirits to clean or flush the torque converter or transmission, damage will occur. Use
only clean automatic transmission fluid designated for the transmission and converter being serviced.
1. If a new or remanufactured torque converter is not being installed, the following steps must be completed.
2. With the torque converter on a bench, pour a small amount of transmission fluid from the torque converter onto an absorbent white tissue or
through a paper filter and examine the fluid.
3. NOTE: The factory fill fluid is red.
Observe the color and odor of the fluid. The fluid should be red, not brown or black. Odor may indicate an overheating condition such as clutch
disc or band failure.
4. Examine the stain on the tissue for evidence of particles (specks of any kind). Examine the transmission fluid level indicator for signs of antifreeze
(gum or varnish). If particles are present in the transmission fluid, a new torque converter must be installed.
5. If there are no particles or contamination present, drain the remainder of the transmission fluid from the torque converter.
6. Add 1.9L (2 qt) of clean transmission fluid into the converter and agitate by hand.
7. Thoroughly drain the transmission fluid.
Torque Converter Diagnosis
Torque Converter Diagnosis
Prior to torque converter installation, all diagnostic procedures must be followed. This is to prevent the unnecessary installation of good torque
converters. Only after a complete diagnostic evaluation can the decision be made to install a new torque converter.
Begin with the normal diagnostic procedures as follows:
1. Preliminary inspection.
2. Know and understand the customer's concern.
3. Verify the condition - carry out the torque converter operation test. See: 5R55S - Automatic Transaxle/Transmission/Torque Converter Operation
