CSF High-Performance DCT Transmission Oil Cooler | A90 Toyota Supra (CSF 8183)

CSF High-Performance DCT Transmission Oil Cooler | A90 Toyota Supra

Keep transmission temperatures under control and maintain consistent shifting performance with the CSF High Performance DCT Transmission Oil Cooler for the MK5 Toyota GR Supra and compatible BMW G Series applications. Developed for demanding street, road racing, drag racing, and tuned vehicles, this direct-fit transmission cooler dramatically increases cooling capacity compared to the factory unit.

CSF developed this cooler after working with performance shops, tuners, and racing teams that experienced transmission heat-related fatigue and sluggish shifting during prolonged or extreme use. The result is an industry-exclusive dual-core design that delivers a 240% increase in core volume and a 130% increase in fluid capacity compared to the OEM transmission cooler.

With 550ml of fluid capacity compared to the factory 240ml capacity, the CSF DCT cooler provides additional thermal capacity to help maintain more consistent transmission temperatures during demanding driving conditions. The design has also been used on the Titan Motorsports A90 Supra drag racing program, demonstrating its suitability for serious high-performance applications.

Industry Exclusive Dual Core Design

Unlike the factory single-core transmission cooler, CSF utilizes two 16mm stacked cores for a combined 32mm core width. The rear cooler increases the factory 12-row design to 15 rows, while an additional 12-row front cooler dramatically expands available cooling capacity without unnecessarily increasing frontal surface area.

The 129mm overall height remains close to the OEM 125mm dimensions, helping maximize transmission cooling without significantly blocking airflow to the rest of the vehicle's cooling system.

CSF Microtube Technology

CSF incorporates technology derived from its AC condenser manufacturing experience, using a single-row, super-high-pressure 16mm microtube with nine internal channels. This design promotes efficient transmission oil flow while maximizing surface area contact for improved heat transfer.

Direct Fit Installation

The cooler is engineered as a drop-in replacement with no vehicle modifications required. OEM-style quick-connect inlet and outlet fittings simplify installation, while compatibility with the factory upper and lower rubber seals helps maintain proper airflow through the cooling system.

The CSF transmission cooler can be used with the factory cooling system or paired with the CSF High Performance Heat Exchanger, part number 8154, for a more comprehensive cooling upgrade.
