2010 JEEP COMMANDER clutch

•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” later in this section.
During cold temperature operation you may notice de-
layed upshifts, depending on engine and transmission
temperature. This feature improves the warmup time of
the engine and transmission.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “TRANSMISSION OVER TEMP” message may display, and the transmis-
sion may downshift out of Overdrive until the transmis-
sion cools down. After cool down, the transmission will
resume normal operation.
In high ambient temperatures with sustained high engine
speed and load, an upshift, followed shortly thereafter by
a downshift, may occur. The “TOW/HAUL Indicator
Light” will turn off. This is a normal part of the overheat
protection strategy when operating in the “TOW/
HAUL” mode.
The transmission will downshift from Overdrive, to the
most desirable gear, if the accelerator pedal is fully
pressed at vehicle speeds above approximately 35 mph
(56 km/h).
When To Use TOW/HAUL Mode — If Equipped
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the “TOW/HAUL” switch. This will improve
252 STARTING AND OPERATING

3. Turn the engine off, and be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.
If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only 2nd gear (3.7L engine) or 3rd gear (5.7L engine)
will be available in the DRIVE position. Have the trans-
mission checked at your authorized dealer as soon as
possible.
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 automati-
cally, at a calibrated speed, at light throttle. It engages athigher speeds under heavier acceleration. This may re-
sult in a slightly different feeling or response during
normal operation in high gear. When the vehicle speed
drops below a calibrated speed, or during acceleration,
the clutch automatically and smoothly disengages. The
feature is operational in Overdrive and in DRIVE.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 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. Manually shifting (using the ERS shift
control) between 4 (direct gear) and 5/D (Overdrive
gear) positions will demonstrate that the transmission
is able to shift into and out of Overdrive. For vehicles
with 5.7L engines (which have two Overdrive gears),
254 STARTING AND OPERATING

“4WD LOW” indicator light in the instrument cluster
will flash and go out when the shift is complete. Release
the T-handle.
NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“CHECK SHIFT PROCEDURES” message will flash
from the Electronic Vehicle Information Center (EVIC).
Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.
•Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being prop-
erly aligned. Several attempts may be required for
clutch teeth alignment and shift completion to occur.
The preferred method is with the vehicle rolling 0 to3 mph (0 to 5 km/h). If the vehicle is moving faster
than 3 mph (5 km/h), the transfer case will not allow
the shift.
NEUTRAL Shift Procedure
1. Key ON, engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a pen,
etc.) for four seconds until the LED light by the switch
starts to blink indicating shift in progress. The light will
stop blinking (stay on solid) when the NEUTRAL shift is
complete. A “4WD SYSTEM IN NEUTRAL” message will
display on the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Information Center
(EVIC)” in Section 4 of this manual.
