The CMP transmission test bench is one of the latest and most variable test benches. By using a modular platform we are able to investigate several engine - transmission combinations.

Furthermore there are different input and output e-machines to model dynamic cycles and test automatic and manual gear changes. It is also possible to simulate variable thermal conditions for a realistic vehicle environment.
