HKS DCT Transmission Oil Cooler Kit for R35 GTR

The HKS DCT (Dual Clutch Transmission) cooler kit for the GTR helps to cool the clutch and regulate transmission oil for a firm, solid shift. The core will be mounted in the front left fender aided by the included air duct and -10AN lines. Includes a new washer fluid reservoir. These kits are a bit different between the CBA and DBA model years. Fitment is not confirmed past 2016.

Vehicle Fitment:
• 2008-2011 CBA Nissan R35 GT-R
• 2012-2016 DBA Nissan R35 GT-R


More Info:
From the street to race circuits, the HKS DCT Cooler Kit for the GT-R has been developed to provide firm and positive shift engagement while assisting in the prevention of overheating the clutch and transmission. By stabilizing and maintaining lower oil temperatures in the transmission, the life cycle of the oil is extended. Integrated with the factory water-cooled transmission cooler and the DCT Cooler Kit also assists in reducing the GT-R's overall water temperature.

• Placement of the DCT cooler core to the front left fender maximizes cooling performance.
• Fiber Reinforced Polymer (FRP) air duct specially designed for R35 GT-R is included to enhance air flow to the core.
• A larger -10 size oil line reduces resistance in pipes and increases flow ensuring proper oil supply.
• The transmission’s stock heat exchanger and HKS thermostat are integrated into the DCT Cooler. With a specially designed oil outlet attachment, stabilizing the oil temperature occurs in a shorter amount of time. Improved shifts are noticeable even after cold starts.
• During testing at Fuji Speedway, the water temperature was reduced by an average of 5°C (41°F) enabling continuous laps at a constant oil temperature of 127°C (260°F).

Core Specs:
• 200 x 220 x 48.5 (mm)
• 15 rows

Install Notes:
• Additional 2L of MT Oil required (Not included)
• Front bumper inner air ducts must be modified
• Washer pump harness must be extended 0.5SQ 250mm x2 (Not included)
• The washer fluid volume will be decreased to 1L (Factory is 1.5L)
• Washer level sensor must be removed (The warning light does not turn on)
• The sound from the factory MT oil pump may be louder

DCT GR6 System Notes:
• Water-cooled type system.
• Fuel safe activates when oil temperature reach 140-145°C (284°-293°F).
• Nissan recommends changing engine oil when oil temperature exceeds 140°.
• Even if transmission oil is below 140°, when the 4WD clutch temperature rises, the drive mode is switched to 2WD. (Warning message appears: The warning appears when oil temperature of drivetrain parts is raised abnormally and improper revolution difference between the front and rear wheels occurs and continues for a certain amount of time.)
