service assistance. Service should be performed immediately in order to minimize
the potential for damage to the transmission.
When the
CHECK TRANS
light comes on and the ignition switch is turned off,
the transmission will remain in
N
(Neutral) until the condition causing the
CHECK TRANS
light is corrected.
Generally, while the
CHECK TRANS
light is on, upshifts and downshifts will be
restricted and
direction changes will not occur
. Lever and pushbutton shift
selectors
do not respond
to any operator shift requests while the
CHECK
TRANS
light is illuminated. The lockup clutch is disengaged when transmission
shifting is restricted or during any critical transmission malfunction.
DIAGNOSTIC CODES
See detailed information in the DIAGNOSTICS section.
ACCELERATOR CONTROL
WARNING:
To help avoid injury or property damage caused by sudden
movement of the vehicle, do not make shifts from
N
(Neutral) to
D
(Drive) or
R
(Reverse) when the throttle pedal is depressed. If you
shift while the throttle pedal is depressed too far, the transmission will
only engage if the throttle pedal is released in the next three seconds.
This may cause a sudden movement of the vehicle. Leaving the throttle
pedal depressed longer than three seconds causes the transmission to
remain in
N
(Neutral). Avoid this condition by making shifts from
N
(Neutral) to
D
(Drive) or
R
(Reverse) only when the throttle is
closed.
The position of the accelerator pedal in
fl
uences when automatic shifting occurs.
An electronic throttle position signal tells the TCM/ECU how much the operator
has depressed the pedal. When the pedal is fully depressed, upshifts will occur
automatically at high engine speeds. A partially depressed position of the pedal
will cause upshifts to occur at lower engine speeds. Excessive throttle position
affects directional changes—shifts from
N
(Neutral) to
D
(Drive) or
R
(Reverse).
DOWNSHIFT AND DIRECTION CHANGE INHIBITOR
FEATURE
NOTE:
Turn off the vehicle HIGH IDLE switch, if present, before
shifting from
N
(Neutral) to
D
(Drive) or
R
(Reverse). The shift from
N
(Neutral) to
D
(Drive) or
R
(Reverse) is inhibited when engine speed
is above idle.
