Remote controlled gear selection and engagement mechanisms Gear selection and engagement is achieved by two distinct movements 1 The selection of the required gear shift gate and the positioning of the engagement gate lever. 2 The shifting of the chosen selector gate rod into the engagement gear position. These two operations are generally performed through the media of the gear shift lever and the remote control tube rod. Any transverse movement of the gear shift lever by the driver selects the gear shift gate and the engagement of the gate is obtained by longitudinal movement of the gear shift lever. Movement of the gear shift lever is conveyed to the selection mechanism via the remote control tube. Initially the tube is twisted to select the gate shift gate followed by either a push or pull movement of the tube to engage the appropriate gear. For the gear shift control to be effective it must have some sort of flexible linkage between the gear shift lever supported on the floor of the driver s compartment and the engine and transmission integral unit which is suspended on rubber mountings. This is essential to prevent engine and transmission vibrations being transmitted back to the body and floor pan and subsequently causing discomfort to the driver and passengers.
