Wallmart Dexron VI & Power Flush

So got a dumb question looking to flush the tranny and replace filters seen wally world has Supertech Dex VI. Has anyone used this and had any trouble with there trannies ?

I thought Dex VI was standard and whether its in a wally world package or a Mobile 1 package its all has to meet the DEX VI standard ???

Second Dumb question: I was also thinking to take it to AAMCO and have them do a "Power Purge" and have them flush the tranny.
I. read through the forums and people are stating in high mileage vehicles that getting a trans, flush done causes particles to get to dislodge and could cause trans to fail. Many state there tranny failed shortly after a Power Flush..... any thoughts on this ?

When you say "Drain and Fill" do you mean dropping the pan changing the filters and refilling.

Or draining through the cooler line and refilling ?

Sorry im handy with a screwdriver just not on vehicles

Anything that's officially licensed by GM for Dexron VI is good to go.

I'm not a fan of flushing machines though. Might want to do a cooler line flush instead without hooking up a machine.
