Back in the day (I love sayin that), when I was learning how to drive on a 3 speed column shifter, my Old Man, who still drives his semi, told me it was bad for the clutch and I assumed he knew what he was talking about with all the gear jammin he's done over the years. Just made it a habit not to I guess. When I owned the 89 SHO, a notorius clutch eater, I got twice the life out of my clutch than most and three times the life of many. It seems to have had some benefit.
