Gearboxes from an international automotive supplier lead to vibrations in the vehicle after a few kilometers. In-house developers and engineers work on a solution for more than two years without any real success. The gearboxes continue to vibrate and recalls increase.

The S.QE experts develop a custom testing procedure and easily locate the error: The clutch piston – perfectly manufactured to comply with all

required tolerances – shows a tiny variation when the car is moving, leading to position deviations in the clutch plates. Altering the design quickly solves the problem, reducing the error rate and failure risk by 95 percent.
