The high mileage fluid changes are always iffy for the simple reason that the clutch packs in the transmission will wear no matter what, and the clutch material gets suspended in the fluid and alters the viscosity and friction profile. When you change the fluid the worn clutch packs are more prone to slippage and it can cause a transmission failure earlier than if left alone.

On the other hand, the fluid will break down slowly over the years and after a certain point it will be less efficient as a lubricant and a hydrolic fluid. It really is a lose lose situation, but the wear on the clutches causing slippage will surface faster after a fluid change than any problems caused by not changing the fluid. (in most cases)
