STARTING AND OPERATING
185
Over Temperature Mode
NOTE:
The transm ission electronics constantly monitor the
transm ission oil tem peratu re. If the transm ission gets too
hot, the transm ission will change the way it shifts to help
control the cond ition. This may resu lt in a slightly
different feeling or resp onse during norm al operation in
D (Drive) position. If the transm ission becom es hot
enou gh the O/ D OFF ind icator light and TRANS OVER
TEMP warning light in the instru ment cluster may come
on. After the transm ission cools down, it will retu rn to
norm al operation.
• transmThe torquissione converterfluid andcluenginetch wcoolantill not engageare warmuntil(uthesu-
ally after 1–3 miles (1.6–4.8 km) of driving). Because
engine speed is higher when the torqu e converter
clutch is not engaged , it may seem as if the transm is-
sion is not shifting into “Overd rive” when cold. This is
consid ered a norm al cond ition. Pressing the “O/ D
OFF” switch will show that the transm ission is able to 5
shift into and out of “Overd rive.”
•
If the vehicle has not been driven for several days, the
first few second s of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transm ission fluid partially draining from the torqu e
converter into the transm ission. This is consid ered a
norm al cond ition and will not cause damage to the
transm ission. The torqu e converter will refill within 5
second s of shifting from P (Park) into any other gear
position.
Torque Converter Clutch
A featu re designed to improve fuel econom y has been
added to the autom atic transm ission of this vehicle. A
clutch within the torqu e converter engages autom atically
at calibrated speed s. This may resu lt in a slightly differ-
ent feeling or resp onse during norm al operation in high
gear. When the vehicle speed drop s or during accelera-
tion, the clutch autom atically and smoothly disengages.
