Within the development of a new vehicle, with significant body changes and minimal modifications of powertrain layout, one of the challenges presented to the working group came from the necessity of a wire bracket to attend requirements of a new proposed layout. In the current paper will be explored the definition and development of this bolted joint, offering alternatives for keeping synergy even facing frequent obstacles, normally inducing to redesign. During the development of this joint, the first configuration tested showed self-loosening and subsequent crack at the aluminum shield. From this start point it could be an opportunity for this joint redesigning, but the challenge is how to do it respecting the project constraints, parameters and characteristics, once the components could not be changed significantly due to project timing objectives.

The challenge to develop a shifter system that achieves a better comfort on shifting gears in manual transmissions is mainly concerned to the subjectivity of the parameters involved, which are strongly based on perception of each customer. This work aims to explore these subjective quality requirements and identify their relation to engineering design parameters. A revision of previous studies on comfort and quality on shifting gears, semi-structured interviews and data from specialized magazines reports are used to define procedures and samples for experimental data acquisition. The results reveal important connections between quality on shifting gears and some design parameters of shifter systems.
