2006 Acura TL - transmission fluid: flush or drain?

[PHXHonda]

I've had Honda dealerships recommend flushes while random friends who own Hondas tell me to just drain.

It's an 06 Acura TL
98xxx miles
never done any tranny fluid change
It's shifting kinda rough

What to do?

Automatic or manual....Manual then you can drain and fill.

Automatic needs to be flushed since most of the Fluid is stored in the torque convertor and draining it will not drain all of the fluid

hondas flush isnt the typical flush. its the 3x3 drain and fill.

drain and fill 3 times with 10-15 miles driven inbetween.

honda doesnt recommend pressurized flushed like gm and ford use
