Car - 1970 Dodge Challenger 340 4-speed. Chased an electrical Gremlin down to the reverse switch in the back of the trans. When I jump the harness switch, backup and dash reverse lights come on. However, when I plug in the harness, nothing. If I remove the switch and push it in with my thumb, everything works. I can see through the switch hole, that the reverse lever inside the trans it right up against hole. I confirmed that the linkage is adjusted properly, and when I manually push the reverse linkage as far back as possible, I can't get the switch to close. It's as if the little ball needs to be in another 1/8 inch or so. The switch looks like a factory part. Did anyone ever have this problem? Is there an improved or alternate switch that reaches a little deeper into the trans?
