97 Civic: Tranny flush or filter change with new fluid

I keep running into this issue and would like some input.

The local Goodyear wants to flush the trans fluid with no filter change
for $179.

For vehicles I have owned before I would get a fluid and filter change.

Is the flush as good if they do not change the filter?

Thanks in advance.

Hondas don't have a changeable filter.

 

You can do the "flush" yourself. For example, drain and fill it once (you
should get about 2.5 quarts of fluid), drive it a couple of days or so and
drain and fill it again, and repeat a couple of more times. If, as an
example, the fill capacity after rebuild is given as 5.7 quarts while the
oil change capacity is given as 2.5 quarts (as it is on an '90 Civic with
an automatic). A rough calculation yields that after 4 changes 9.9% of the
original fluid would remain while after 6 changes 3.3% of the original fluid
would remain. Note that I don't know if the volumes given in the service
manual include the ATF cooler so those percentages may vary slightly.
