Transmission Service Kits

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.

BMW’s Getrag GS7D36SG Dual-Clutch Transmission is a masterpiece of engineering. It's renowned for its rapid gear changes, robust construction, and direct, motorsport-inspired feel. While the transmission itself delivers exceptional performance, its supporting components don’t always keep pace. The factory plastic oil pan and limited oil capacity compromise cooling efficiency and long-term reliability, especially during high-performance use. With this in mind, we set out to engineer a solution that elevates durability, thermal management, and fluid control to match the transmission’s world-class performance.

We've designed a permanent, high-performance replacement for the flawed OEM pan: a cast-aluminum, increased-capacity upgrade that enhances cooling and durability. Its all-aluminum construction provides a significant upgrade over the OE plastic pan, which is prone to cracking when impacted by road debris. Engineered for those who demand more from their vehicle, our design increases fluid capacity to promote superior cooling and help maintain optimal transmission temperatures, even in the most demanding conditions.

To ensure a leak-free seal, we engineered a heavy-duty Viton gasket specific to their transmission pan design. The Viton material provides exceptional reliability under high temperatures and resists deformation—a common failure point of the factory rubber gasket. For further protection, integrated magnets actively attract and hold metal debris that could otherwise compromise the transmission's longevity. This innovative design keeps your fluid clean and extends the overall life of your drivetrain.

Whether your DCT-equipped BMW serves as a track car or a highway cruiser, this pan ensures your transmission remains cool and efficient, minimizing the risk of overheating and wear.

High-Capacity Aluminum Transmission Pan Includes gasket, drain plug, and installation hardware. DCT Suction Filter (optional) DCT Pressure Filter (optional) 8 Liters of DCTF-1 Fluid (optional) PRODUCT DEVELOPMENT

Our High-Capacity DCT Transmission Pan was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

The DCT transmission in your BMW is nothing short of incredible and exhilarating, but also astronomically expensive to replace. BMW has been labeling fluids as "lifetime" for quite some time now, and as enthusiasts and owners have learned over the years, there simply is no fluid that last a lifetime.

This DCT service kit that takes the guesswork out of a fluid change . No need to track down the correct fluid and plugs, simply open the box, and get the job done the correct way. By servicing your DCT transmission, you will be assured that old, broken down fluid won't cause a several thousand dollar nightmare. We recommend this service every 40,000 miles to keep your transmission going strong for years to come.

Kit includes:

• 5 quarts of Pentosin DCTF-1 fluid
• DCT transmission cartridge and suction filters
• Drain and fill plugs

Please note: We include 5 quarts of DCT fluid because without a GT1 diagnostic tool and much more involved labor, you will not be able to replace over 5 quarts of fluid. Many elect to do this service and simply flush the fluid 5,000 miles later to ensure all fluid has been flushed, but this is not mandatory.

Both the cartridge and suction filters have their own challenges in replacing. For best results, replace both.

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.

Kit Includes:

• Automatic transmission filter with associated hardware
• Oil pan gasket
• Drain plug with sealing washer
• Fill plug with sealing washer
• 7 quarts automatic transmission fluid
