IF.....the fluid was actually 'black' it is indicating a problem already exists.....trans fluid gets burned when clutch's slip, not through normal usage.
I doubt if your fluid was burned, otherwise you would be asking about other problems.
Service writers are taught by BG to say this if asked....they likely never saw the fluid.
The filter can only be exchanged if the trans case is 'split' for service....it would have to be out of the car for this.....so, per Chevrolet, the filter is considered a 'Life of Transmission' component.
This leads us to 'Why is flushing not recommended by the manufacturer?'
Any debris that was dislodged....debris that was causing no harm where it was, now has been freed up to potentially restrict the non serviceable filter......with that, the potential of a pressure restriction causing the clutch's to slip.....burning them and the fluid.....and then, around we go....now, for sure the fluid is black and the trans requires reconditioning which will get you a nice new filter.
OK, enough doom and gloom......if the trans was shifting fine, the odds are favorable that you'll be fine.
But for future knowledge, no manufacturer recommends flushing and all caution against it........they have seen too many failures that were a result of the process, so..........
