My neighbor is a technician / Team Leader at the local Mercedes dealer (Penske), and he says the 722.6 is the most bullet proof transmission MB ever built (from 2000-on).

He says he never sees a failure.

In fact, when MB went to the 6 speed transmission in the 211 chassis, they kept using the 722.6 in the AMG models because the 722.6 can handle the torque.

In fact, the Mercedes / McLaren SLR uses the 722.6.
