BMW Transmission Parts for BMW 1 Series

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.

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

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 oil pan with integrated filter 
• Oil pan gasket
• Drain plug with sealing washer
• Fill plug with sealing washer
• 7 quarts Redline D4 automatic transmission fluid
