There's plenty of FUD out there about it. Depends on how the 'flush' is done. Most people shoot their shot at maintenance when they're already down the path of having trans issues, have the flush done, and then something happens. Well, it was probably going to happen anyways, so the 'flush' gets blamed.Yeah, they had to pull the pan to do the flush, or so they told me, and replaced the filter at that time. I read an article that said “not” to flush high mileage automatic transmissions.
If you're maintaining like you should have.....
And keep in mind, 'like you should have' in regards to a 10X transmission (I use this to cover all 10R's and GM 10L's) is NOT every 150k. Not if you want to keep your truck, and not if you want the best life out of the transmission. Drain and fill every 30K minimum.
...then a 'flush' will be no problem.
If you're more on the side of having longer changes, then simply draining, or vacuuming and refilling the trans is a much more gentle and 'safer' way to go.
Nate from NextGen does a fantastic job explaining.
