If the tranny flush worked once, it was probably the tranny.
My 1999 CL was the same generation as your Accord, and the 4-speed
auto really sucked as you described from day one. At 30k I had it
flushed on scheduled maint, and for the first time I could accelerate
out of cruise without the tranny slipping then downshifting two gears
instead of one racing the engine, and other crap.
I suspect *most* Honda products of that period have this problem to
one extent or another, and drivers baby their cars and don't notice,
or figure it's the engine computer or other intended behavior, when
it's really seriously sucky transmission performance.
The five speeds seem a little more solid now, but after they had to
fix or replace a couple hundred thousand of them on six-cylinder
engines, you be the judge.
The bad trannies are really Honda's dark secret.

======================================
When you do a drain-n-fill on a Honda automatic it's supposed to be
three times, or four. You may have only replaced about 1/3 rd of the
capacity. Be sure to use only Honda Z1, no substitutes. At 120,000 MILES
and 8 years you owe your tranny a bit of care for sure.

Re: Car studders durring acceleration...
I'm having a very similar problem with a much older Honda (1987
prelude).
I'm certainly no expert but in my car it seems to be related to either
ignition or fuel delivery because it sounds suspiciously like a car
running out of gas. I have a 5 speed manual transmission which
reinforces my thinking that it's not related to the tranny. I've had a
vehicle where the clutch slips and another where the gears are stripped
and it doesn't feel like that at all. It feels as though the engine is
just not firing due to lack of fuel or failure to spark.
I managed to download a shop manual which had a troubleshooting chart.
The troubleshooting table suggests any number of things could be
the problem when you have a lack of power at lo/mid/hi RPM
* fuel injector open or short circuited, stuck injector (they do seem
to be leaking)
* faulty fuel pump / fuel pump relay OR poor grounding
* improper fuel line pressure OR clogged fuel filter
* manifold absolute pressure sensor - open or short circuited, broken
or disconnected hose, faulty sensor

Re: Car studders durring acceleration...
I'm having a very similar problem with a much older Honda (1987
prelude).
I'm certainly no expert but in my car it seems to be related to either
ignition or fuel delivery because it sounds suspiciously like a car
running out of gas. I have a 5 speed manual transmission which
reinforces my thinking that it's not related to the tranny. I've had a
vehicle where the clutch slips and another where the gears are stripped
and it doesn't feel like that at all. It feels as though the engine is
just not firing due to lack of fuel or failure to spark.
I managed to download a shop manual which had a troubleshooting chart.
The troubleshooting table suggests any number of things could be
the problem when you have a lack of power at lo/mid/hi RPM
* fuel injector open or short circuited, stuck injector (they do seem
to be leaking)
* faulty fuel pump / fuel pump relay OR poor grounding
* improper fuel line pressure OR clogged fuel filter
* manifold absolute pressure sensor - open or short circuited, broken
or disconnected hose, faulty sensor
