A reduction in the level of vibration in the gearshift lever module in the cabin of automobiles may affect a positive effect on driver comfort. The vibrations to the gearshift lever module is transferred through transmission control cables (TCCs) connected to the shift levers attached to the body of a transmission or transaxle. Countermeasures for the reduction of vibration are presented by analyzing vibration characteristics of TCCs employed in the conventional gearshift lever modules. The analysis was carried out by analytical and experimental approaches including the construction and analysis of finite element (FE) models for the module. By utilizing the results from the analysis a vibration reduction method was proposed and its applicability was also investigated. It is observed from the investigation that the proposed method is a viable solution to the vibration reduction problem in gearshift level modules and ride quality improvement.
