BMW Transmission Oil Cooler - do88 OC-210
Improve the performance of your 2021+ BMW G8X M2/M3/M4 with the do88 Transmission cooler, a cooler designed for optimal transmission temperatures under demanding driving conditions!
Background
For the 2021+ BMW G8X M2/M3/M4 models, the ZF 8HP automatic gearbox is robust and fast, designed to handle the high-power output of the S58 engine. However, upgrading the engine with additional performance parts and tune can overwhelm the original cooling system especially during track driving. The risks when overheating the transmission is slower gear changes and the possibility of damaging the transmission. To address this temperature challenge, do88 has developed an upgraded transmission cooler to help keeping the temperatures at a correct level and having the transmission operating correctly.
Our solution
The do88 performance transmission cooler for the 2021+ BMW G8X models significantly improves the cooling efficiency. Our engineers redesigned the transmission cooler's core, increasing its volume by 71% and the cooling surface area by 50% while maintaining similar oil pressures. We upgraded the tubes with harmonica tubes with internal channels, ensuring optimal cooling efficiency. It also increases the system's cooling capacity with a 42 % (8,5 dl vs 6 dl) rise in oil volume. The do88 cooler uses a dual-pass design which means the fluid stays in the cooler for longer time, ensuring more heat is dissipated.
Installation
Installing the much larger do88 Performance Transmission Cooler is hassle-free, requiring no modifications (see installation instructions).
Key Features:
- Core volume increased by 71 % and the active cooling area by 50 % compared to the original cooler (OE).
- Harmonica tubes ensure optimal oil flow and maximum surface area contact.
- OEM-style “Quick Connect” inlet/outlet connections.
- Drop-in fit, eliminating the need for modifications.

do88.se is an online Swedish vendor hosted and governed by do88 AB. do88 is based in Nykvarn, outside Stockholm, and was founded in 2007. Our business started with universal silicone hoses, and has since grown to become one of the largest silicone hose distributors in the northern hemisphere. We keep everything in stock and ship worldwide. Being Swedes, we started focusing on SAAB and Volvo, which led us to develop our own model-specific parts that go beyond just hoses. Our expertise now extends to intercoolers, oil coolers, radiators, intake systems, and much more, for a variety of car brands and models. All products are developed in-house and sold based on our criteria. Our commitment to proven performance, high quality, and excellent customer support has established do88 as a respected name in the auto parts industry. We also offer related products including plastic connections, aluminum piping, hose clamps, heat protection, and BOVs from GFB, as well as air filters from BMC and intercooler cores from industry titan Garrett. Our goal is to be the clear choice for automotive and industrial cooling needs.
