BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

GA8HP 8 speed automatic transmission. Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This item fits the following BMWs: E71,E89 Z4,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4,F30,F31,F32,F33,F34,F36

The F97 X3M and F98 X4M are powered by the same high-performance S58 engine found in the G8X M3, M4, and M2. While these SUVs deliver impressive power and speed, they also suffer from the same heat management challenges as their sedan and coupe counterparts. That’s where CSF’s advanced cooling solutions come in—becoming essential upgrades for S58 owners, even for those keeping their engines mostly stock. After over a year of development and testing, CSF is proud to introduce the Front Mount Heat Exchanger & Transmission Cooler Module for the F9X X3M and X4M. One of the biggest challenges in developing a Front Mount Heat Exchanger for these models was limited space. Unlike the G8X models, the X3M and X4M feature a different transmission oil cooler, restricting the available room for a larger heat exchanger due to the mounting cradle. After extensive testing with smaller core designs, CSF determined that integrating the Heat Exchanger with a Transmission Cooler Upgrade was the optimal solution for maximizing both size and performance. By combining both components into a single cooling module, CSF achieved a design that accommodates the same core size as the G8X Heat Exchanger. The integrated Auto Transmission Cooler utilizes the same dual-core design as the G8X Transmission Cooler and is seamlessly fitted to the new Heat Exchanger. This innovative all-in-one module not only addresses two major cooling issues for the X3M and X4M but also reduces overall costs—savings that are passed along to the customer. Compared to the stock heat exchanger, CSF’s upgraded design offers significant improvements. The TIG-welded aluminum tanks are much larger than the OE plastic tanks, providing superior strength and fluid volume. A 2-row 42mm core increases cooling efficiency and capacity, utilizing CSF’s Exclusive B-Tube Technology to enhance airflow and heat dissipation. Multi-louvered fins further expand the heat exchange surface area, improving overall cooling performance while maintaining proper airflow. Built entirely from high-strength aluminum, this system ensures maximum durability and reliability. The mounting tabs and brackets are significantly stronger than the factory plastic components, offering improved longevity. Additionally, the heat exchanger includes an integrated bolt-on metal rock guard, which is far more robust than the stock plastic version—providing better protection against road debris and ensuring greater confidence in the system’s resilience. CSF’s Transmission Cooler features an innovative dual-pass design that dramatically enhances cooling performance. Unlike the OEM single-core cooler, CSF’s front-to-back stacked core design more than doubles the surface area and nearly triples the core volume. Engineers leveraged the extra space freed up by replacing the OE cooler and oversized plastic cradle, effectively doubling cooling capacity while maintaining a perfect OEM fit—no modifications required. By switching from a single-core to a dual-core design, CSF achieved a 201% increase in overall volume, significantly improving heat dissipation and fluid capacity. Using CSF’s AC Condenser Technology, the cooler incorporates a high-pressure 1-row 16mm 9-channel microtube design, optimizing oil flow and maximizing surface area contact. These features work together to provide the most effective heat dissipation possible, keeping transmission temperatures under control even under extreme conditions. With CSF’s new Front Mount Heat Exchanger & Transmission Cooler Module, X3M and X4M owners can enjoy superior cooling efficiency, enhanced durability, and long-term performance—all in a cost-effective, OEM-fit package.
