Manual six speed  BMW transmissions in used, good working condition. These had to be imported from Europe, since they were never sold in the US and are very hard to come by.
 
These are not to be confused with the GS6-53BZ, which are from gasoline (petrol) cars. These are GS6-53DZ from diesel cars. This specific variant is highly legendary in the car-tuning and drifting communities because of its extreme bulletproof reliability and torque capacity. While officially rated for up to 600 Nm (443 lbf⋅ft) of torque, real-world abuse has proven that a healthy GS6 53DZ can comfortably survive over 1,000 Nm (738 lb-ft) of torque without breaking.
 
These will be shipped via LTL freight. Once you purchase, email us and we will provide freight quotes. It's usually around $140 to 280 within the US. 
 
*Note that these will not bolt up to any Mercedes-Benz engine. You'll need an adapter kit.
