Hard to Shift Out of Gear

If your drive shifts fine with the engine off, but refuses to come out of gear with the engine running the problem is the shift interrupter switch or mechanism.
	As you shift out of gear, the tension on the shift cable causes this device to kill the ignition for an instant. This momentary interruption removes the load on the gears and allows the dog clutch to disengage.
Most likely this switch is not working. It is also possible that the spring loaded shift bracket is not able to move freely. You can test the switch by running the engine and moving the switch manually. The engine should die with a slight moment of the switch arm. Do not try and adjust this by bending the arm, replace the switch. Make sure the shift bracket is free to move.
