If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fourth gear). The transmission will
automatically shift into Overdrive if the following con-
ditions are present:
• the shift lever is in the DRIVE position,
• the transmission fluid has reached an adequate
temperature,
• the engine coolant has reached an adequate
temperature,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the accelerator.
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 until
the transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (2 to 5 km) of driving]. Because the
engine speed is higher when the torque converter clutch is
not engaged, it may seem as if the transmission is not
shifting into Overdrive when cold. This is normal. Shifting
between the DRIVE and 3 ranges, when the transmission is
sufficiently warm, will demonstrate that the transmission is
able to shift into and out of Overdrive.
