GTR-28GT-R Overview
TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.T�fe GT-R transmission design is different from transmissions used in �bonventional passenger �bars. T�fe GT-R uses a transmission gear
design, lig�ft flyw�feel and a dry sump lubri�bation system to provide maximum ve�fi�ble performan�be. Be�bause t�fe GT-R Transmission design
is different, noises may be louder. W�fen t�fe transmission temperature is �fig�f, rattling, s�faking and jarring noises may be �feard.
.Clattering noises may be �feard w�file s�fifting..Appropriate gaps are provided between gears to a�b�fieve smoot�f gear rotation and steady toot�f surfa�be lubri�bation under t�fe �fig�f-load
driving �bondition. However, t�fis �bauses a rattling noise.
.If t�fe s�fift lever is moved from&Rto&A
F&Mposition, or&A
F&Mto&Rposition before t�fe ve�fi�ble stops, you may not be able to s�fift gear
or it may take longer to s�fift gear. Make sure to depress t�fe brake pedal and �b�fe�bk t�fat t�fe ve�fi�ble �fas stopped before s�fifting.
Multiple dis�b wet �blut�b�f
.W�fen stopping t�fe ve�fi�ble wit�f t�fe s�fift lever in t�fe&Ror&A
F&Mposition, be sure to firmly depress t�fe brake pedal. T�fe ve�fi�ble may
slowly move if t�fe brake pedal is not depressed.
.Avoid depressing t�fe brake and a�b�belerator pedals at t�fe same time. Depressing t�fe brake and a�b�belerator pedals at t�fe same time �bould
�bause t�fe �blut�b�f to over�feat and a�b�belerate deterioration.
.W�fen t�fe ve�fi�ble is stopped on a �fill, do not �fold t�fe ve�fi�ble in pla�be by depressing t�fe a�b�belerator pedal. Doing so may �bause t�fe �blut�b�f
to over�feat and result in transmission damage. Use t�fe brakes to prevent t�fe ve�fi�ble from moving.
Ele�btroni�b oil pressure
�bontrol T�fe following �bonditions are �baused due to �b�fanges in fluid vis�bosity as a result of temperature �b�fanges.
.W�fen t�fe transmission oil is extremely �bold or extremely �fot, t�fe transmission may feel like it is slipping during s�fifts or t�fere may be �fard
s�fifts. T�fis is normal. Transmission s�fifting s�fould return to normal w�fen t�fe transmission oil returns to normal operating temperatures.
.W�fen t�fe transmission oil temperature is extremely �bold, t�fe time required to run a system �b�fe�bk may in�brease. During t�fe system �b�fe�bk,
t�fe s�fift lever must stay in t�fe&Pposition. Move t�fe s�fift lever after turning off t�fe system �b�fe�bk display. Also, it is normal to �fear �bli�bking
noises during t�fe transmission systems �b�fe�bk.
C�fanging modes
.T�fe �fig�fer s�fift speeds in t�fe&Mposition may result in s�fift s�fo�bk and jerkiness w�fen starting or s�fifting..T�fe qui�bkest s�fifting in t�fe R mode wit�f t�fe transmission in t�fe&Mposition is available w�fen t�fe engine speed is �fig�f. However, t�fe
transmission may s�fift more slowly w�fen t�fe engine speed is low.
Me�b�fani�bal Limited Slip
Differential (LSD) If t�fe ve�fi�ble a�b�belerates from a stop wit�f t�fe steering w�feel turned �falf a turn in �bold temperatures, t�fe inner w�feel tire may slip and some
noise or vibration may be �feard. T�fis p�fenomenon o�b�burs be�bause t�fe vis�bosity of t�fe differential oil be�bomes t�fi�bker and t�fe Limited Slip
Differential (LSD) operates wit�f in�breasing load. W�fen t�fe steering w�feel is returned to t�fe straig�ft a�fead position or t�fe differential oil warms
up, t�fe noise and vibration de�brease.

1. Check the positions of the accele\fato\f pedal
*1and b\fake pedal*2. Ad\bust the stee\fing
wheel and seat positions so that the co\f\fect
d\fiving postu\fe is achieved. (
“F\font
seats” page 1-3)
2. Check that the pa\fking b\fake is engaged.
3. Check that the shift leve\f is in the
&Po\f&N
position. (&Pis \fecommended.)
4. Fi\fmly dep\fess the b\fake pedal. Without dep\fessing the accele\fato\f pedal, push the
ignition switch once to sta\ft the engine.
5. To stop the engine, move the shift leve\f to the
&Pposition, and push the ignition switch
to the OFF position. NOTE:
.
Care should be taken to avoid situa-
tions that can lead to potential battery
discharge and potential no-start condi-
tions such as:
a. Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
b. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
. If the engine is difficult to start, de-
press the accelerator pedal all the way
to the floor and hold it. Push the
ignition switch with the brake pedal
depressed to start cranking the engine.
After 5 or 6 seconds, stop cranking by
pushing the ignition switch to the OFF
position, and then release the accel-
erator pedal. Then perform steps 1 to 5
to start the engine. If the engine starts,
but fails to run, repeat this procedure.
. Starting and stopping the engine over a
short period of time may make the
vehicle more difficult to start. If this
occurs, wait for more than 3 minutes, and then push the ignition switch again
to start the engine.
. To maintain high performance over a
long period of time, the engine speed is
limited to 5,000 rpm when the engine is
revved with the shift lever in the
&Nor
&Pposition, and to 4,000 rpm when the
engine oil or coolant temperature is
low or higher than normal.
. If the ignition switch is pushed before
the shift lever is moved to the
&P
position, the ignition switch will not
change to the OFF position. If this
occurs, the SHIFT
&Pwarning display
appears on the vehicle information
display. When stopping the engine, be
sure to move the shift lever to the
&P
position and then push the ignition
switch. Failure to do so may result in
discharge of the battery. (
“Shift
“P” warning” page 2-43)
. If the shift lever was in the
&A
F&Mor&R
position when the engine was stopped,
then be sure to move the shift lever to
the
&Pposition before starting the
engine the next time. If the engine is
started with the shift lever in the
&N
position, then it may not be possible to

5-16Starting and driving
medical devices or other electronic
products that are susceptible to
magnetic force close to the shift
lever.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
. If the shift lever is moved from
&Rto
&A
F&Mposition, or&A
F&Mto&R
position before the vehicle stops,
you may not be able to shift gear or
it may take longer to shift gear.
Make sure to depress the brake
pedal and check that the vehicle
has stopped before shifting.
CAUTION
.Because the vehicle includes a dual
clutch transmission that automati-
cally controls the clutch and shifting
operation of the manual transmis-
sion, whenever the shift lever is in a
position other then
&Por&N, the
vehicle will begin to move slowly, in
the same way as when the clutch in
a manual transmission vehicle is partially engaged. Keep the brake
pedal firmly depressed when the
vehicle is stopped. In some circum-
stances the vehicle may not start
moving on its own, however this
does not indicate that there is a
malfunction.
NOTICE
.
When the vehicle is stopped on a
hill, do not hold the vehicle in place
by depressing the accelerator pedal.
Doing so may cause the clutch to
overheat and result in transmission
damage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmission is
provided with a dry sump lubrication
system that improves efficiency and
ensures reliability under high g-
force conditions. When oil viscosity
is high at low temperatures, it takes
longer for all components to be
sufficiently lubricated. Thus, when
the transmission temperature is low
(approximately 104 8F (408C) , do not
accelerate rapidly or run the engine faster than 4,000 rpm.
