TRANSMISSION OIL

Visually check transmission assembly surrounding area (oil seal, drain plug, filler plug, transmission case, etc.) for smears and leakage of transmission oil.

• *1: When the oil does not drop
  
• *2: When the oil drops
  

Oil smears/leakage status from transmission assembly		Required operation	Reference
Smears*1	Smears from each part on the transmission assembly	Use part cleaner or the equivalent to wipe out smeared oil. Then, check for oil leakage.	—
Leakage*2	Mating surface between oil pan and case	Check the seal surface condition. Replace the oil pan gasket only if there is a non-standard condition. Check for oil leakage.	Exploded View
	Park position switch mounting surface	Check the mounting surface condition. Replace the plain washer only if there is not any other malfunctioning condition. Check for oil leakage.	Exploded View (GT-R certified NISSAN dealer)
	Heat exchanger & bracket mounting surface and heat exchanger mounting bolt	Check the seal surface condition. Replace the O-ring at the location where the oil leakage occurred if there is not any other malfunctioning condition. Check for oil leakage.	Exploded View (GT-R certified NISSAN dealer)
	Front oil seal	Check the oil seal mounting surface and sliding surface condition. Replace the front oil seal only if there is not any other malfunctioning condition. Check for oil leakage.	Exploded View (GT-R certified NISSAN dealer)
	Drain plug	Replace the drain plug. Check for oil leakage.	Exploded View
	Filler plug	Replace the filler plug gasket. Check for oil leakage.	Exploded View
	Transmission harness connector	Replace the transmission assembly.	Exploded View (GT-R certified NISSAN dealer)
	3rd-5th check pin Idler bolt Plug	Replace the plain washer or O-ring. Check for oil leakage.	Exploded View

Remove the filler plug, insert a finger into the filler hole, and judge the oil conditions from the transmission oil applied to the inside of the transmission case.

■ CAUTION ■

Be careful not to cut the finger with edges.

Transmission oil status	Possible cause	Required operation
Varnish-like condition (It is as thick as varnish).	Clutch is burned.	Change the transmission oil. Check the transmission assembly or any other parts on the vehicle.
Milky or cloudy	Water is mixed in the fluid. Example: Inflow of engine coolant by internal explosion of heat exchanger Inflow of water from breather by flood, etc.	Change the transmission oil. Check for flooded area.
A large amount of metal particles are contained in the fluid.	Sliding portions in the transmission assembly are excessively worn.	Change the transmission oil. Check the transmission assembly operation for any malfunctioning condition.

NOTE：

Replace the filler plug gasket and drain plug with new ones after oil level adjustment.

1.Remove the filler plug () and drain plug, and then fill with the transmission oil until it leaks from the drain hole.




Transmission oil

: Refer to General Specification.



■ CAUTION ■
• Always use the specified transmission oil. In addition, always use the filler after cleaning. If use/mixed use/misuse of the transmission oil other than the specified brand occurs, the original performance cannot be obtained or it may cause serious malfunctions.
  
• Check that dust does not mix.
  
• Always use paper towels. Never use waste cloth.
  

2.Install the filler plug and drain plug. Refer to Exploded View (filler plug), Exploded View (drain plug).

3.Start the engine and select the M range.

4.With depressing the brake pedal, shift the paddle shifter to the N range → M range, 1st gear (wait for 5 seconds) → M range, 2nd gear (wait for 5 seconds) → M range, 1st gear → N range at idle.

5.Stop the engine.

6.Remove the filler plug and drain plug, and then fill with the transmission oil until it leaks from the drain hole.

7.Install the filler plug and drain plug. Refer to Exploded View (filler plug), Exploded View (drain plug).

8.Install the heat insulator.

9.Start the engine and run it at idle. Run the engine until the oil temperature reaches 50°C (122°F) while checking FLUID TEMP in “DATA MONITOR” of CONSULT-III.

10.With depressing the brake pedal, shift the paddle shifter to the N range → M range, 1st gear (wait for 5 seconds) → M range, 2nd gear (wait for 5 seconds) → M range, 1st gear → N range at idle.

11.Stop the engine and wait for 5 minutes.

12.Remove the drain plug. Install the drain plug when the transmission oil begins to drip (1 drop/1 second). Refer to Exploded View.
■ CAUTION ■
• Perform from step 11 to step 12 within 25 minutes.
  
• Repeat the procedure from step 6 if the transmission oil does not leak from the drain hole.
  
• Never reuse drain plug.
  

13.Replace the filler plug gasket with new ones.
■ CAUTION ■
Never reuse filler plug gasket.

14.Install the front diffuser. Refer to Exploded View.

NOTE：

Replace the filler plug gasket and drain plug with new ones after oil level adjustment.

1.Remove the front diffuser. Refer to Exploded View.

2.Remove the heat insulator.

3.Start the engine and select the M range.

4.With depressing the brake pedal, shift the paddle shifter to the N range → M range, 1st gear (wait for 5 seconds) → M range, 2nd gear (wait for 5 seconds) → M range, 1st gear → N range at idle.

5.Stop the engine.

6.Remove the filler plug () and drain plug, and then fill with the transmission oil until it leaks from the drain hole.
