By 2020, some 105 million transmissions of all types are expected to roll off the production line, 35% more than in 2010.

Today, the world market is divided almost equally between manual transmissions (all types) and automatic transmissions (all concepts: AMT, DCT, BVA, CVT), a situation that will change little in the future. By 2020, the worldwide breakdown of transmission types should be as follows: BVM (50%), BVA (28%), CVT (10%), DCT (8%), electrified transmissions (4%).

The transmission sector has undergone profound changes in recent years, driven by a number of constraints linked to customer expectations or...
