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.
