ATF, ATF filter, and ATF pan gasket Change Procedure

Yes, but I wasn't talking about the gasket for the ATF pan.
I was talking about the small gasket for the ATF drain plug.
You ommited to mention that gasket--a common mistake or
oversight; I wouldn't worry about it :-P

Just like the engine oil's drain plug has a small round,
washer-like gasket, so does the ATF pan's drain plug.

I'll quote the Camry service and repair manual again:

2. DRAIN AUTOMATIC TRANSAXLE FLUID

(a) Remove the drain plug and gasket, and drain ATF.

(b) Install a new gasket and drain plug.

Torque: 36 ft-lbf

Earlier I wrote that the total fill for the 2006 Camry's AT fluid
is 9.3 quarts. That's true for the V6 Camry which uses the
U151E transmission, but the 4-cylinder 2006 Camry uses the
U250E transmission, which has a total fill of 8.5 quarts.

If just doing a simple ATF drain-and-fill, just 3.7 quarts
is required for both the U151E and the U250E, because
most of the rest of the ATF is in the torque converter, in the
AT oil cooler (the short length of pipe underneath the radiator),
and in the hoses which connect to the AT oil cooler.

The 2 hoses on my Camry leading from the transmission to the
AT oil cooler are actually labeled with the words "AT Oil."
Toyota helpin' out to simplify things :-)

I don't think I'll ever do anything more than a drain-and-fill
of the ATF, though. When I crawled under the chassis to
take a look at the ATF pan, I saw that several of the 18
bolts are recessed away in hard-to-reach awkward spots.
You'd have to be plastic man to reach those bolts or have
really flexible tools.

Has anyone ever removed their own car's ATF pan to
replace its gasket and screen-filter or clean the
magnets and clean the ATF pan itself? I guess after 20
years it might make sense...

Why do the ATF hoses come into play when you drain/refill? How about
using the drain plug?

The U250E, like many other U-series transmission, suffer from shift
problems. IMO the older A-series, while dirtier, was more reliable.
After driving highway speeds and decelerating the U250E may exhibit a
harsh 5-4 shift.

Get a new shift solenoid free before the powertrain warranty expires!!

Automatic transmissions fail because the fluid was not changed (or the
wrong fluid was used), and/or from overheating due to excessive towing
weights.

Ray, you wrote that you've [quote]"mentioned several times
that changing the transmission strainer is not necessary, but
you do not have to take my word and experience for it."

You also wrote, "How many 20 year old transmission screens
(actually called a strainer) have you looked at that need
replacement? I haven't seen any."

Ray, my man, can you point out where I stated that the
transmission filter requires changing? Why are you implying
to the group that I have ever said that?

You seem to be putting words in my mouth so that you can pretend
to come along and correct something I said, which I never said.
Odd that you would feel the need to do that.

And it sounds like you're blowing a gasket, too [chuckle]. Try to
relax a little more, my friend :-)

I've been busy all weekend, but finally had a chance to
catch up with the thread.

Chill out, Ray :-)

Well, I'm not going to argue with you. The passage of
mine you quoted just now shows I did not say replacing
the ATF strainer was required.

I'll just end now by saying you do give
good Toyota advice.
