TRANSMISSION OPERATION CHARACTERISTICS
Mechanism Operation characteristics
Base Manual transmission
. The GT-R transmission design is different from transmissions used in conventional passenger cars. The GT-R uses a transmission gear
design, light flywheel and a dry sump lubrication system to provide maximum vehicle performance. Because the GT-R Transmission design
is different, noises may be louder. When the transmission temperature is high, rattling, shaking and jarring noises may be heard.
. Clattering noises may be heard while shifting.
Multiple disc wet clutch
. When stopping the vehicle with the shift lever in the &
R
or &
A
↔&
M
position, be sure to firmly depress the brake pedal. The vehicle may
slowly move if the brake pedal is not depressed.
. Avoid depressing the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause the clutch to overheat and accelerate deterioration. Also, the engine may stall.
. 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.
Electronic oil pressure
control
The following conditions are caused due to changes in fluid viscosity as a result of temperature changes.
. When the transmission fluid is extremely cold or extremely hot, the transmission may feel like it is slipping during shifts or there may be hard
shifts. This is normal. Transmission shifting should return to normal when the transmission fluid returns to normal operating temperatures.
. When the transmission fluid temperature is extremely cold, the time required to run a system check may increase. During the system check,
the shift lever must stay in the
&
P
position. Move the shift lever after turning off the system check display. Also, it is normal to hear clicking
noises during the transmission systems check.
Changing modes
. The higher shift speeds in the &
M
position may result in shift shock and jerkiness when starting or shifting.
. Quick shifting in the R mode with the transmission in the &
M
position is available when the engine speed is high. However, the transmission
may shift more slowly when the engine speed is low.
Gear clearances
Appropriate gaps are provided between gears to achieve smooth gear rotation and steady tooth surface lubrication under the high-load driving
condition. However, this causes a rattling noise.
Ultralight flywheel
. An ultralight flywheel is provided to achieve rapid engine response to the accelerator pedal operation. The engine rotation fluctuations
become larger than conventional vehicles. Rattling, shaking or jarring noises may be heard when idling or driving at a low speed.
. Rattling noises may be heard when the engine is started or stopped.
Dry sump lubrication
High-efficiency dry sump lubrication is provided to achieve low agitation resistance of lubricant oil and allows smooth transmission gear rotation
that contribute to obtain a perfect balance between outstanding driving performance and improved environmental performance. However, you
may notice some rattling noise due to engine rotation fluctuations.
