HKS Oil Cooler AT Transmission 370z Z34 - 27002-AN001

**HKS Automatic Transmission Cooler Kit for Nissan Fairlady Z  Nissan 370z (Z34) - Part Number: 27002-AN001**

Keep your Nissan Fairlady Z (Z34) performing at its best during spirited driving with the HKS Automatic Transmission Cooler Kit. Designed specifically for the Z34 equipped with the VQ37VHR engine, this cooler prevents the transmission from entering fail-safe mode during high-temperature conditions, which can occur when the automatic transmission fluid overheats. By maintaining optimal fluid temperatures, the AT cooler ensures consistent performance, particularly during sport and track driving sessions.

**Key Features:**
- **Prevents Fail-Safe Mode:** The Z34 can enter fail-safe mode when the automatic transmission fluid temperature exceeds 145°C for over 120 seconds or reaches 150°C. This cooler kit helps prevent these conditions, ensuring reliable manual operation and full throttle control.
- **Enhanced Cooling Performance:** The 9-row core cooler measures W200 x H130 x T32 and is strategically placed in front of the radiator for maximum cooling efficiency. It works seamlessly with the HKS Oil Cooler Kit to manage both engine and transmission temperatures during demanding driving.
- **Track-Tested Results:** In testing at Fuji Speedway, the stock transmission overheated after just 7 laps at 10°C air temperature, triggering fail-safe mode. With the HKS AT Cooler installed, the vehicle was able to run continuously for 25 minutes at 30°C without entering fail-safe mode.
- **Easy Installation:** Designed for straightforward installation without major modifications, though removal of the resin protector is required. Installation time is approximately 1.5 to 2 hours.

**Kit Components:**
- AT Fluid Cooler Core (W200 x H130 x T32, 9 rows)
- Cooler Core Bracket
