When the manual transmission will not transmit power from the engine to the wheels, and one gear will not shift, it is possible that the gear is stripped. If the transmission will not shift in all gears, it is possible that the input, or countershaft gears are stripped, or a broken input or output shaft has occurred. Sometimes the transmission shift control may not be working correctly.
