First: Thank you for any and all replies to my post...everyone has always
been very helpful...enough smooching!
Second: I am about to do a full transmission fluid flush and am wondering
how many quarts of ATF to purchase. I believe twelve quarts usually cover
most vehicles but if I can get a more specific number for a 4-cylinder 1990
Camry (btw, it only has just over 110k miles--a baby, practically). In the
past I have replaced the transmission filter and just replaced whatever ATF
that drained out, usually with about three to four quarts of ATF, but I
would like to give her a full transmission flush and fill.
Third: Any specific ATFs, or requirements\specifications, to purchase that
might extend life\performance would be greatly appreciated.
You would be bettered served to have your tranny flushed at a
shop that uses a flushing machine. One must flush enough fluid
through the tranny to clean the converter as well. Simply
changing the fluid is not a good idea, that alone will not change
the fluid in the converter or clean it. Tranny fluid is loaded
with detergents, the new fluid you install will begin to clean
and loosen the gunk therein and that can lead to trouble. It is
better to let a flushing machines do the cleaning, leaving the
tranny filled with all new fluid afterwards.

I've heard of disasters occuring just after flushing, and because
Toyotas have drain plugs on their transmission pans, why not just
change the fluid every 15,000 miles?
No doubt, but the disasters are much more likely to occur after a
mere fluid change than a machine flush for the reason I stated..

You can buy a lot of quality trans fluid for the $120 it cost to have it
flushed! I'd go with a drain and refill every 15-30k or so.

Then why do owner's manuals and factory service manuals give
instructions for drain/refill but not for flushing?
I know you appear to be simply asking question but I don't post
opinions, I post what I know to be factual.
My suggestion to flush rather than simply drain the tranny comes
from our experience servicing thousands of vehicles annually. I
stated clearly the reasons why a flush is better and I'm
certainly not going to debate every joker
in a NG that wants to save a few dollars on a fluid change.
If one chose to avoid that advice, that is certainly their
privilege, I could not care less.
