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. You should also perform a static shift and dynamic shift test.
The number(s) below refer to the step number(s) on the diagnostic table.
This step checks for worn or damage shift control components.
