4SRC Nissan GT-R R35 Transmission Cooler Kit

Advanced Thermal Management Solution for the GR6 DCT

The 4SRC Transmission Cooler Kit for the Nissan GT-R R35 is engineered to deliver enhanced thermal stability and long-term reliability for the GR6 dual-clutch transmission system.

Developed with inspiration from proven high-performance cooling concepts used in top-tier Japanese motorsport engineering, this kit provides a substantial improvement in oil temperature control under demanding driving conditions.

Whether on aggressive street setups or repeated track sessions, maintaining optimal transmission fluid temperature is critical to preserving clutch performance, shift precision, and gearbox longevity.

Key Features

High-Efficiency Heat Exchange Core

Utilises a high-capacity oil cooler core designed to maximise surface area and airflow exposure, significantly improving heat dissipation efficiency.

Optimised Oil Flow Design

Engineered to maintain stable oil pressure while increasing cooling capacity, ensuring consistent lubrication and protection under sustained load.

Track-Ready Thermal Stability

Reduces temperature spikes during repeated acceleration, hard launches, and extended circuit use — minimising heat soak and performance fade.

OEM-Integrated Fitment

Designed specifically for the Nissan GT-R R35 platform with precise mounting geometry for clean installation and factory-style integration.

Increased Transmission Reliability

Lower operating temperatures help extend transmission fluid life and reduce thermal stress on clutch packs and internal components.

Why Upgrade Your R35 Transmission Cooling?

The GR6 DCT transmission is highly sensitive to heat. Elevated oil temperatures can lead to:

• Reduced clutch efficiency

• Premature fluid degradation

• Increased internal wear

• Limp mode activation under extreme conditions

The 4SRC Transmission Cooler Kit is designed to combat these issues by delivering consistent temperature control, even in high-power or tuned applications.

Suitable For

• Street performance builds

• High-horsepower tuned GT-R setups

• Frequent track day users

• Hot climate operation

• Owners seeking preventative reliability upgrades

Technical Fitment Information

The 4SRC Transmission Cooler Kit has been developed to ensure full compatibility across all Nissan GT-R R35 model years.

All primary components of the system — including the cooler core, mounting brackets, oil lines, fittings and hardware — are engineered for direct installation on all R35 variants without year-specific modification.

The only component subject to front bumper configuration is the supplied cooling duct. The duct is dimensioned for direct installation with MY17–MY23 (EBA) front bumper models. Vehicles equipped with MY07–MY16 front bumpers may require a minor length adjustment to the duct to ensure correct positioning and airflow alignment. This modification is limited to trimming the duct to suit the earlier bumper profile.

No other part of the kit requires alteration for model year differences.
