Manual transmission is one of the key system of power-train to which driver directly interacts, so its shift feeling is important for the merchantability. The importance of the gear shift quality of manual transmissions has increased significantly over the past few years as the refinement of other vehicle systems has increased and also due to rise in customer expectations. Shift Tower is a system to assist the driver during selecting and shifting of Gears. The dynamic interaction of shift Tower at a component level is difficult to interpret by traditional test methods and virtually impossible at concept stage. To overcome these difficulties a dynamic model of the entire Shift Tower mechanism i.e. Shift select lever, 3D Ramp, Detent Pin, Spring, Interlock mechanism has been created. The model predicts the gearshift quality i.e. Shift and Select force values for a given set of input parameters, which can be correlated against test data.
