I have a Tremec TKO 600 in my 67 Camaro SS and my reverse lights stopped working. If I bypass the switch I can get the lights to work. The switch is just a 2 lead sensor that screws into the side of the tranny, it has a ball bearing that is pushed in by something inside the tranny when shifted to reverse and makes the contact. I removed the switch and tested by pushing on the ball and checking the resistance across the terminals. I got a reading of 5-7, does it sound like the switch is no good?
