I’ve been remiss about getting results back to readers. I took the car to the Honda dealer who pushed hard for the power flush . . . only to have the technician do the 3X manual flush. Turns out that only some 2003 V6 Accords have the available connections to handle power flushing.
Results? The transmission has been Smoooooooooth ever since — how could it NOT be when the old fluid looked and smelled like old, overcooked coffee? Because the final draining still smelled a little off, I’ll probably do yet another tranny drain with the next oil change.
Thanks for the advice.
