I would almost agree with c500s, and know of 1 company that removed the inching master cylinders when they were new, not because they knew the inch valve would leak in to the transmission, but because they didn't want inching. in 2001, they still had 50 units running 3 shifts. they gave the forklift repair shop foreman a company Cadillac Eldorado, for having saved so much over the years by not needing to replace their fleet.
