Service Bulletin \- Torque converters may not have been manufactured to proper specifications. As a result, the torque converter lock\-up clutch cannot provide adequate holding force due to pressure bleeding down through a crack in the lock\-up piston. The reduced lock\-up clutch capacity results in DTC P0741 Torque Converter Clutch Circuit Performance or Stuck OFF.
