DUAL CLUTCH

- It is equipped with 2 wet clutches, clutch A and clutch B, and each clutch is engaged or released by the hydraulic piston.
- If there is no oil pressure, the return spring forces the piston to return, releasing the clutch.

SHIFT DEVICE

- Each synchronizer is activated by its own shift actuator (hydraulic cylinder).
- Borg Warner type triple cone synchronizer is used for all the gear speeds.
- A friction material is affixed to the cone surface of the synchronizer to allow higher capacity than a normal cone made of copper alloy.
- The actuator control module is a unit integrated with the shift actuator and hydraulic control valve.

SHIFT LEVER

- It inputs the range position (P, R, N, A ⇔ M) and Auto/Manual range change switch signal to the TCM.
- It is connected to the parking device of the transmission with the control cable, and it locks the parking device only when the shift lever is shifted into the P position.

PADDLE SHIFTER
It inputs the switch signal of upshift or downshift to TCM.

1 | : Paddle shifter (shift-down switch)
2 | : Paddle shifter (shift-up switch)

SET-UP SWITCH (TRANSMISSION)

- It inputs the switch signal of R mode or SNOW mode to TCM.
- Refer to the following table for driving mode shifts during range shifting (A Range to/from M Range).
  When shifting from A Range to M Range

  Range | A Range | Shift from A Range to M Range | M Range
  Driving Mode | R mode | ⇒ | R mode
  Normal mode | ⇒ | Normal mode
  SNOW mode | ⇒ | Normal mode

  When shifting from M Range to A Range

  Range | M Range | Shift from M Range to A Range | A Range
  Driving Mode | R mode | ⇒ | R mode
  Normal mode | ⇒ | Normal mode
  Normal mode (When not operating the setup switch after shifting to M Range with A Range in Snow mode) | ⇒ | SNOW mode

DISPLAY DEVICE

Message content | Display timing | Erasure procedure | Remarks
T/M SYSTEM MALFUNCTION VISIT DEALER | When a DTC is detected by self-diagnosis and an inspection is necessary at GT-R certified NISSAN dealer |

- Turn the ignition switch ON again after turning OFF
- Erase the DTC using CONSULT-III

Always blink the transmission warning light when this message is displayed
SHIFT TO THE P RANGE |

- When the engine start operation is performed in any range other than P or N
- When the engine starts while the shift lever is in N range and the gear is engaged

Shift the shift lever to the P range
—
CHECK POSITION OF SHIFT LEVER | When the shift lever position cannot be detected | Shift the shift lever into either range of P, R, N, A ⇔ M | —
T/M SYSTEM CHECK IN PROCESS | When the diagnosis is performed just after the engine starts while the shift lever is in the P range | Wait for a short period of time until the diagnosis is completed | While this message is displayed, the shift lock solenoid prevents the shift lever from moving out of the P range
T/M OIL TEMP HIGH DECREASE SPEED | When the high oil temperature control is active because of high transmission fluid temperature | When the high oil temperature control is deactivated |

- Always illuminate the transmission warning light when this message is displayed
- To see if there is a history of this message, check history of phenomena in “High oil temperature protection history” on CONSULT-III Function (GT-R certified NISSAN dealer).

T/M CLUTCH TEMP HIGH STOP VEHICLE UNTIL WARNING TURNS OFF | When the clutch protection control is active because of high transmission clutch temperature or stall driving | When the clutch protection control is deactivated |

- Always illuminate the transmission warning light when this message is displayed
- To see if there is a history of this message, check history of phenomena in “Clutch overheat protection history” on CONSULT-III Function (GT-R certified NISSAN dealer).

Shift position indicator
Upon receiving the CAN output signal from TCM, the drive gear position appears and blinks, and the range is displayed.

A | : Range position and drive gear position (A/M range)
B | : A range or M range

Transmission warning light
It illuminates and blinks with the CAN output signal from TCM.

ON | It shows an intermittent malfunction such as high transmission fluid temperature

- When the transmission warning lamp turns ON, the following possibilities may be included:

- Transmission oil temperature is high
  (History of phenomena can be checked in “High oil temperature protection history” on CONSULT-III Function (GT-R certified NISSAN dealer).)
- Transmission clutch temperature is high
  (History of phenomena can be checked in “Clutch overheat protection history” on CONSULT-III Function (GT-R certified NISSAN dealer).)
- Line pressure is low
  (History of phenomena can be checked in “Line pressure loss history” on CONSULT-III Function (GT-R certified NISSAN dealer).)
- When clutch gear learning value is not recorded in TCM
  (“WORK SUPPORT” on CONSULT-III Function (GT-R certified NISSAN dealer).)

Blinking | It shows that a malfunction requiring a check occurs

- When the transmission warning lamp blinks, the following possibilities may be included:

- When DTC of transmission is detected be self-diagnosis
  (Check “Self Diagnostic Result” of “TRANSMISSION”.)
- When IP characteristics value is not recorded in TCM
  (“CONFIGURATION” on CONSULT-III Function (GT-R certified NISSAN dealer).)
- When learning is not completed without recording clutch gear learning value in TCM
  (“WORK SUPPORT” on CONSULT-III Function (GT-R certified NISSAN dealer).)

Mode indicator
R mode lamp and SNOW mode lamp illuminate by the analog output signal from TCM.

A | : R mode lamp
B | : SNOW mode lamp

Multi-function display
The drive gear position, range position, transmission oil pressure and transmission oil temperature are displayed by the CAN output signal from TCM.

A. | Transmission oil temperature | B. | Transmission oil pressure | C. | Range position and drive gear position (A/M range)
D. | A range or M range |  |  |  |
