Does power flush on automatic transmission help prevent transmission failure?

It should be called a transfusion of fluid in my opinion. The term flush is not a accurate discription but everyone seem to want to call it a flush. We do that service in our shop and its main benefit is it changes all the fluid in a transmission versus a drain and refill does not. I think its a good service but we do not doing it on centain makes of transmiisions after the car goes over 100k miles and if its never been serviced previously.

THATS CALLED A FLUID EXCHANGE AND IT REPL ALL FLUID VERSES 45 % OF FLUID, IT IS A GOOD SERVICE AND I REC IT.
