  Summary

  CVT Transmissions only. This bulletin announces the availability of a countermeasure torque converter assembly to address a customer concern of very low engine RPM when coming to a stop. The condition is similar to coming to a stop in a manual transmission equipped vehicle without depressing the clutch pedal. Thrust washer wear inside the torque converter can cause restriction of the oil passage used to bleed off lock-up clutch application pressure. The result is either a delayed (momentary low engine rpm) or no lock-up pressure release. The thrust washer has been changed from a solid bushing-type to a needle bearing type.

  Summary

  Post launch conditions may occur where certain combinations of inputs result in undesirable outputs. As such it is critical to gather all the details surrounding these events to allow SBR and Harman the ability to duplicate and then evaluate what is needed and then improve the system accordingly to prevent the undesired outcome in the future.
