Default Did an ATF flush today at home

My Camry's so happy now that she has T-IV inside her again. She
shifts so well with T-IV.

About 3 weeks ago, I did a drain and refill with Mobil 1 Synthetic
ATF, making the ATF about 45% Mobil 1 and 55% T-IV (we'll say 50/50).

Today I did an ATF oil cooler hose flush to replace the 50/50
mixture of Mobil 1 and T-IV with 100 percent T-IV (or near 100 percent).

I quickly noticed an improvement in shifting during the first 40 miles
of driving after the flush. I'm sure Mobil 1 Synthetic ATF is a great
ATF; it's just not meant for my Aisin U250E tranz. I don't think I'll
ever veer from Toyota T-IV again.

Smooth shifting, no more occasional jerkiness, less shudder when
switching into and out of reverse, and fewer down-shifting probs.

The U250E's total capacity is probably 8.5 quarts (the Amsoil site
doesn't know). To perform the flush, I bought 13 quarts (a case and
a loose quart) from Machens Toyota yesterday for $4.83 per quart.
Sure beats the $7 they originally quoted me.

To start things off, I did a drain and refill of the pan's 3.7 quarts.
Then did a flush using the tranz-in hose, which enters the transmission
at a lower spot than the tranz-out hose, unlike what the author of the
tutorial mentioned (he said it's "usually the upper of the two
lines"--not so with the '06 Camry). With the '06 Camry, the tranz-in
hose (or return hose) is closer to the driver side than the passenger side.

The hose's spring clamp opened by using an 8-inch slip-joint pliers
I bought from Harbor Freight. A second, smaller pliers was also helpful
during the re-application of the clamp to the hose. There's limited room
to work in there. Both pliers came in handy, the bigger and the smaller.

After the 3.7-quart drain and refill, I flushed with 8 quarts of T-IV
ATF. (Actually, I flushed with about 7.3 quarts and added another 0.7
quart after I had driven the car for about 34 highway miles to get the
ATF nice and hot for more accurate checking on the dipstick--didn't want
to overfill).

I may yet add another 0.25 or 0.3 quart after checking the dipstick level
after a 100-mile trip to St. Louis. That ought to get the ATF nice and hot.
Looks like the dipstick shows I can put in another 0.25 or 0.3 quart. But
I'll wait for the 100-mile drive to verify. Right now when hot, the fluid
level on the dipstick is midway between the 2 cool zone notches and the
2 hot zone notches.

During the flush, I added a quart or 1.2 quarts at a time while the car
idled, but I would have to turn off the car after a quart or so because
I couldn't keep up with the faster outflow of the ATF into the drain pan.
When I saw the stream from the hose begin to break up, I'd shut the car
off and pour in a second quart. Then I'd turn the car back on and let it
idle while pouring another quart or so down the ATF dipstick tube.

Sorry to be so detailed, but I'm making notes so I can review them if
I ever need to do another flush. I'll probably only do drain and refills
from here on out, though, because they're faster than flushes. I did
enjoy my first ATF flush, but I think the second time would just seem
like a chore. However, first time was very interesting and fun. Definitely
worth doing at least once.

I'm not sure, but I think your problem was mixing different lubricants. The
transmission would not like that at all. It is a bad practice to do that,
and I think you just learned why.

Don't bother with the last cup or two of fluid, it won't change anything
except how long it takes to add the full quart.

You have far more serious issues than being a cup low on fluid. The most
critical issue is that you did not flush the transmission at all.

Please tell me that you did not reuse the clamps. Please! Those clamps are
one-time use only. If you have to take them off, they should be discarded
and replaced with a standard hose clamp, or another clamp like the one you
just tossed into the trash -- except you didn't toss it, did you?

Jeff, I'm sorry to correct you, but you don't seem to know very much
about transmissions, certainly not as much as some of the transmission
experts on BobIsTheOilGuy.com . Those hose clamps are re-usable,
according to a 2-week-old post made by a transmission *expert* on
the Bob discussion board.

And I guarantee you the clamps in my car are working very well--no leaks
at all.

Jeff, I've been wanting to ask this of you for quite a while.
It must be very interesting being part of a family that is
half Fundamentalist Christian and half Jewish. Can you talk
a little bit about that, if it's not an intrusive question.

???

It's not intrusive, but it's also not true so I can't answer it.

I'm sorry about the clamps, I had my head up my ass. I visualized the type
of clamp that is pressed on, and requires you to pry it open. You have the
type that is made of spring steel that you squeeze to open. This type can be
used over again.

You still did not drain and refill the transmission properly though.

What did you hope to gain by changing the transmission fluid to a
50/50 mix?
