No reverse lights. Complete diagnostics reveal; good Fuses, good blubs, good continuity, good reverse light switch. The switch was checked two ways: 1. jumped out with a piece of wire between connection contacts (lights work) 2. remove switch from transmission and physically depress actuator (lights work).
Suspect some slight changes to Transmission (shifts fine) recently; replaced UJoints in drive shaft, replaced center mount bearing, topped off manual transmission fluid. This beauty has 202K "cared for" mileage.
Therefore, I sense that the switch must now travel slightly further into the transmission to facilitate actuation. Am I right?
