The HKS DCT Cooler Kit Nissan GT-R R35 is a high performance Dual Clutch Transmission Cooler Kit for Nissan GT-R R35 from HKS. The DCT Cooler Kit has been developed to provide firm, 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, 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 efficiency.
- The included, specially designed, Fiber Reinforced Polymer (FRP) air duct is used to enhance air flow to the core.
- A larger -10 size oil line reduces resistance 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).
DCT (DUAL CLUTCH TRANSMISSION) GR6
Stock System Specifications:
- Water-cooled type system.
- Fail safe mode –transmission oil temperatures of 140-145°C (284°-293°F).
- Nissan specifies that the oil needs to be replaced immediately once oil temperatures exceed 140°C (284°F).
- When clutch temperatures are too high, the vehicle will switch from 4WD to 2WD, even if transmission oil temperatures are below 140°C (284°F). (Prolonged speed differences between the front and rear tires and high drivetrain oil temperatures may cause this “fail-safe warning” to appear.)
