Torque Converter
INTRODUCTION
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.
COUNTERMEASURE IN PRODUCTION
The countermeasure torque converter was incorporated into production October 1, 2013 starting with
transmission #633208. Remanufactured CVT assemblies with a production date of 12/31/2013 or
later as indicated on the shipping container label include this revised torque converter.
