Tested this mod on the bh drive over the last season. What I have done is created a resivior of oil in the shift chamber. I fill it with hi perf merc gear oil. So the shift slider and drive shift mechanism all rides in gear oil. I have found that the oil lubes the cable as well. In the pic there are two holes dlilled and taped with drive oil plugs. One is used to pump oil in the other a fill vent.
