The switch has a button tha tis pushed when it is put in gear it rides against the shifter rail to push the button in and then when out of reverse there is adetent that the ball goes into, Your truck would not be able to go into reverse if the shift rail was broken, maybe it's worn out and causing this. I would take the washer off the switch if there is one on it and put it in the trans like that without the washer to see if it will go in farther or not. Both the 4 speed an d5 speed work the same way. As long as the switch gets power and it goes through then the lights should work. Make sure to check the connection or put power to one side of switch then test other side of switch to see if power is going through, it may be just a poor connection there that is causeing your problem.
