H2 Transmission Flush or Not to Flush

[gram]

The things about using a flush machine is it the tranny has any kind of shifting problem, the flush is usually no help and can even finish off your tranny. The clutch discs desintagrate and all the friction material ends up in the fluid. So when you flush out the fluid for new fluid yourability for the clutches to grab disappears with the old fluid. But usually the fluid is black and smells burnt. There is no substitute for a real flush machine. It is the only way to clean out all the old dirty fluid. But you will have to change the filter after, cause it pushes all the dirt from the rest of the tranny into it. Brown is still ok to use the machine, black forget about it.
