I've used both but I always bought the adjustable where available. I believe there is a set screw in the vacuum tube that can alter the shift points. Granted, not by much but it did add a little flexibility.

both of mine are adjustable, but it calls for a small on car & large on truck,
factory know's truck will get used harder i wondering if it raises the line to
help trans not to slip as much, none of my books has anything(i can find)
on the difference's just that you adjust for shift points and "firmness"???
