Upgraded gearbox including BlackBoost Transmission
7-speed automatic transmission (722.9)
Heavy-duty gearbox upgrade for high-performance vehicles – designed for significantly increased torque values and maximum durability.
Description
The upgraded transmission, including BlackBoost Transmission, was developed for vehicles equipped with the Mercedes-Benz 7-speed automatic transmission (722.9) , which must withstand significantly higher loads as a result of increased performance. Targeted reinforcements and optimized internal components significantly improve mechanical and thermal durability. The goal is reliable power transmission during sporty driving and performance-oriented setups.
