DUAL CLUTCH TRANSMISSION BRAKE DUST This vehicle is equipped with high performance brakes, and the characteristics of the brake pad material may cause more brake dust than other vehicles. NISSAN recommends a wheel coating that helps prevent the brake dust from sticking to the wheels. Contact a GT-R certified NISSAN dealer for more details. The GT-R dual clutch transmission is a newlydeveloped system that uses an electronically controlled multiple-disc wet clutch attached to the highly efficient manual transmission. This transmission has two driving modes. . A & position (Automatic gearshift): passenger car transmissions. Because of this, the GT-R has different operating characteristics, and various rattle noises may be heard during some driving conditions because of the following items: ...Gear clearances Ultralight flywheel Dry sump lubrication allows automatic shifting of the manual transmission. allows quick shifting of the manual transmission. MECHANICAL LIMITED SLIP DIFFERENTIAL (LSD) CHARACTERISTICS The differential oil has a high viscosity and is very thick when cold. If the vehicle accelerates from a stop with the steering wheel turned in cold temperatures, the inner wheel tire may slip and some noise or vibration may be heard. This phenomenon is unique to vehicles equipped with the Limited Slip Differential (LSD). When the steering wheel is returned to the straightahead position or the differential oil warms up, the noise and vibration decrease. . M & position (Manual gearshift): These noises do not indicate that there is a malfunction. NOTE: . M & position driving is recommended when driving up hills or accelerating from a stop on a cold morning. M & position driving is recommended if you feel shift shocks or jerkiness in the A & position in cold temperatures. . . When starting or driving on a steep M uphill grade, shift to the & position and operate the paddle shifter to shift down to 1st gear similar to a manual transmission vehicle. The GT-R dual clutch transmission was developed specifically to maximize vehicle performance and driving enjoyment. The GT-R transmission components were designed using different engineering standards than typical GT-R Overview GTR-9
