Automatic transmission Acura MDX 2011 User Guide

To shift up or down, use the＋
(right) or －(left) paddle shifter on
either side of the steering wheel.
Each time you pull ＋(right), the
transmission shifts to a higher gear.
Pull －(left) to downshift. You will
see the selected gear number on the
instrument panel.When you pull either paddle shifter,
the gear position indicator shows you
the selected gear number. The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as in
normal driving, the system judges
that you are driving at a constant
cruising speed without using the
paddle shifters. Under these
conditions, D-paddle shift mode is
canceled, and the transmission
automatically returns to drive mode
(D).
Hold the
＋(right) paddle shifter for
2 seconds to return to drive mode
(D).
When the transmission returns to
drive mode (D), the displayed gear
number goes out.
The transmission remains in the
selected gear if you do not
accelerate. Each time you pull either paddle
shifter, the transmission shifts one
gear up or down. If you want to shift
up or down more than two gears, pull
the paddle shifter twice, pause, and
then pull it again.
The automatic transmission will not
allow you to shift up or down if:
●
You downshift before the engine
speed reaches the highest
threshold of the lower gear.
If you try to do this, the gear
position indicator will flash the
number of the lower gear several
times, then return to a higher gear.
●
You upshift before the engine
speed reaches the lowest
threshold of the higher gear.
●
You press both paddle shifters at
the same time.

●
You press one of the two paddle
shifters while another paddle
shifter is being pressed.
●
You are trying to downshift from
second to first with the accelerator
pedal off. This will only work when
the accelerator pedal is applied
deeply.
The transmission downshifts to first
gear and returns to drive mode (D)
when the vehicle comes to a
complete stop and the vehicle speed
is about 6 mph (9 km/h).
If there is a problem in the
transmission while you are driving
with the paddle shifters, the D
indicator flashes, the D-paddle shift
mode is canceled, and the
transmission returns to drive mode
(D). Using the Paddle Shifters in the S
position (Sequential Shift Mode)
With the shift lever in the S position,
you can select the sequential shift
mode to shift gears; much like a
manual transmission using the
paddle shifters, but without a clutch
pedal.
To enter the sequential shift mode,
press the release button on the front
of the shift lever, move the lever to
the S position, then pull either paddle
shifter. To cancel the sequential shift
mode and return to the ordinary
automatic transmission, move the
shift lever from S position. When
moving the shift lever, be careful not
to operate incorrectly. While you are
driving in the sequential shift mode,
the transmission will not
automatically return to ordinary
automatic transmission.
When you move the shift lever from
‘‘
D ’’to ‘‘S ’’ position and pull either
paddle shifter, the gear position
indicator displays the selected gear
number.
Shifting between first and second
gears may occur automatically.
Downshifting from second to first
with the accelerator pedal off is not
allowed.

To upshift, pull the＋(right) paddle
shifter. To downshift, pull the －
(left) paddle shifter.
When you accelerate from a stop, the
transmission starts in first gear, and
shifts from first to second
automatically. You must manually
upshift between second and sixth
gears. Make sure you upshift before
the engine speed reaches the
tachometer's red zone.
The transmission remains in the
selected gear (6, 5, 4, 3, or 2). There
is no automatic downshift when you
push the accelerator pedal to the
floor.
When you are driving, the
transmission downshifts to the lower
gear under the following conditions:●
The vehicle slows down to a
certain speed.
●
You press the brake pedal. Downshifting with the paddle shifter
allows you to increase the engine
braking when going down steep or
long hills, and provides more power
when climbing uphills. You can
upshift the transmission manually to
reduce the rpm.
The transmission also shifts
automatically as the vehicle comes to
a complete stop. It downshifts to first
gear when the vehicle speed reaches
6 mph (9 km/h) or less.
The automatic transmission will not
allow you to shift up or down if:
●
You downshift before the engine
speed reaches the highest
threshold of the lower gear.
If you try to do this, the gear
position indicator will flash the
number of the lower gear several
times, then return to a higher gear.
●
You cannot upshift with the paddle
shifter before the engine speed
reaches the lowest threshold of the
higher gear.
●
You try to shift to third or a higher
gear when the vehicle is
stationary.
●
You press both paddle shifters at
the same time.
●
You press one of the two paddle
shifters while another paddle
shifter is being pressed.
●
The vehicle detects that you are
driving uphill or downhill.

Towing Speeds and GearsDrive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D position when towing a
trailer on level roads. See‘‘
Driving on
Hills
’’ for additional gear information.
When towing a fixed-sided trailer (e.
g., camper), do not exceed 55 mph
(88 km/h). At higher speeds, the
trailer may sway or affect vehicle
handling. If the automatic transmission fluid
temperature increases and exceeds
the specified limit, the A/T
temperature indicator comes on (see
page 70). You will also see a
‘‘A/T
TEMP HIGH ’’message on the multi-
information display.
Making Turns and BrakingMake turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses.
Allow more time and distance for
braking. Do not brake or turn
suddenly as this could cause the
trailer to jackknife or turn over.
Driving on HillsWhen climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shift down to S
position, or use the paddle shifters to
lower gear (3 or 2) in the S position.
When towing a trailer, do not ‘‘ride ’’
the brakes, and remember, it takes
longer to slow down and stop when
towing a trailer.

Check the fluid level with the engine
at normal operating temperature.1. Park the vehicle on level ground. Start the engine, let it run until the
radiator fan comes on, then shut
off the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) before
doing step 2.
2. Remove the dipstick (yellow loop)from the transmission, and wipe it
with a clean cloth.
3. Insert the dipstick all the way intothe transmission securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should be between
the upper and lower marks.

5. If the level is below the lowermark, add fluid into the dipstick
hole to bring it to the level
between the upper and lower
marks.
Pour the fluid slowly and carefully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment.
Always use Acura ATF DW-1
(automatic transmission fluid.)
6. Insert the dipstick all the way back into the transmission securely as
shown in the illustration.
Make sure the rubber cap on the
dipstick fits in the dipstick guide
and that you push the dipstick in
all the way. The transmission should be drained
and refilled with new fluid when this
service is shown on a maintenance
message on the multi-information
display.
If you are not sure how to add fluid,
contact your dealer.
Use only Acura ATF DW-1 (automatic
transmission fluid). Do not mix with
other transmission fluids.
Using transmission fluid other than
Acura ATF DW-1 may cause
deterioration in transmission operation
and durability, and could result in
damage to the transmission.
Damage resulting from the use of
transmission fluid other than Acura
ATF DW-1 is not covered by the Acura
new vehicle warranty.
