BMW Drivetrain Parts for BMW 3 Series G20 (2019+)

Clear BMW chassis

Please ensure your correct model is selected

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.

The ZF 8-speed automatic transmission (8HP) has become the go-to choice for performance enthusiasts, delivering lightning-fast shifts, impressive torque handling, and ample tuning potential. However, the stock transmission pan falls short in critical areas. Its plastic construction, integrated non-replaceable filter, and limited fluid volume leave little margin for error in demanding conditions.

To address these limitations, we've engineered a premium solution: a cast aluminum transmission pan that boosts durability, cooling performance, and serviceability. Designed with enthusiasts in mind, this upgraded pan increases fluid capacity by 1 liter to reduce transmission temperatures and improve long-term reliability, even under aggressive driving or track conditions.

Built to outlast and outperform the OEM plastic pan, the aluminum construction resists damage from road debris and eliminates the risk of cracking. Our pan is hard-coat anodized in black for superior corrosion protection and a long-lasting finish that looks as good as it performs.

Our aluminum pan upgrade is engineered to work seamlessly with the OEM G8X 8HP transmission filter (24007855263), allowing for easy and cost-effective fluid service. Integrated magnets help to trap metal particulate, extending the life of your transmission by keeping contaminants out of the fluid.

Key Features:

Cast aluminum construction offers superior strength and resilience over the OE plastic pan

Increased fluid capacity (+1L) enhances thermal management and reduces the risk of overheating

Serviceable design uses the OEM G8X transmission filter for easy, affordable maintenance

Hard coat anodized finish provides exceptional corrosion resistance and longevity

Integrated magnets collect metallic debris, protecting transmission internals

The stock center support bearing carrier is designed to reduce NVH to the cabin by loosely holding the center bearing with a flimsy rubber bushing. During launches and shifts, the driveshaft is allowed to travel off-center, decreasing throttle response and causing oscillations through the drivetrain. As they age, the carrier rubber sags and dry rots, ruining the driveshaft alignment. Fix or prevent this common issue with JXB Performance's Driveshaft Center Support Bearing Upgrade! JXB utilizes a simple but extremely effective 2-piece design which allows you to install this upgrade and replace bushings with ease. The stock center support carrier is simply cut away, allowing the JXB bushings to "clamp" down on the driveshaft bearing and hold the driveshaft securely in place, maintaining driveshaft alignment at all times. Two bushing options are available for this kit, Street and Track, both of which are many times better than the stock bushings: The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. (With a modified exhaust or windows down, you’ll probably never hear it) The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? Try them both, they’re interchangeable! Installation does not require the removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. Looking for replacement or additional bushings? See T#4799658 for replacement street bushings and T#4799659 for replacement track bushings.
