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

Installation:

Vehicle plastic belly pans may vary. Because the Turner 8HP transmission pan is taller to allow for increased fluid capacity, some vehicles may require trimming of the plastic belly pan, or the belly pan may need to be installed over the transmission pan where it may make contact.

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Kit Includes: OEM Hengst Automatic transmission filter OEM Hengst Oil Pan Gasket & Installation Hardware OEM Hengst Drain plug with sealing washer OEM Hengst Fill plug with sealing washer 7 Liters of Liqui-Moly Top Tec 1800 ATF NOTE: Depending on the model, an additional liter of fluid may be necessary if you are draining your oil cooler or removing the valve body. As per ZF's recommendations, Turner Motorsport suggests performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle is modified and makes more power than stock or if your vehicle is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination which will help extend the life of internal transmission components like clutch packs and solenoids.

Transmission oil pan with integrated fluid filter. Found in all variants of 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.

Includes two OEM FAG rear wheel bearing and hub assemblies plus Genuine BMW axle bolts and installation hardware Wheel bearings can need replaced for a number of reasons, the most common being normal wear. If there is a loud humming, growling, or metal-to-metal noise while driving, it's likely that the bearing has failed. A simple way to check your bearing is to lift the wheel off the ground and try to move the tire back and forth by pushing the top and bottom of the tire in. If there is play, this commonly means the wheel bearing is worn out or has failed completely. The wheel hubs and bearings are already pressed together, simply bolt this new hub assembly to your rear wheel carrier.
