Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle. A
clutch within the torque converter engages automatically at
calibrated speeds. This may result in a slightly different
feeling or response during normal operation in the upper
gears. When the vehicle speed drops or during some
accelerations, the clutch automatically disengages.
NOTE:
•
The torque converter clutch will not engage, and the
transmission will not shift into the top overdrive gear,
until the transmission fluid and engine coolant are warm
[usually after 1 to 3 miles (2 to 5 km) of driving]. Because
top gear is disabled, and engine speed is higher when the
torque converter clutch is not engaged, it may seem as if
the transmission is not shifting properly when cold. This
is normal. Using the Electronic Range Select (ERS) shift
control, when the transmission is sufficiently warm, will
demonstrate that the transmission is able to shift into and
out of Overdrive.
•
If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the transmis-
sion into gear may seem sluggish. This is due to the fluid
partially draining from the torque converter into the
transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds after starting the engine.
