Default A/T shifting erraticaly

My A/T seems to rev then catch under load when I romp on it. No codes. At other times it shifts normally and occasionally it seems to go in and out of overdrive.
Again no codes.
Flush and fill?
Filter and fluid change?
Last done 40 k ago.
Any outside itens on the tranny that affects downshifting?

Thanks in advance
