Thanks Glenn. I thought maybe there was a filter in there, but if it is just a strainer, that solves my dilema. Thanks again for the help. I'll let you know what I see in there.

Rubix,
From looking at a transmission assembly diagram, I don't think it is really a filter but a oil strainer that can be cleaned and re-used. I looked up the part # and it is about $50. By the way there are magnets in the pan for attracting metal particles.

Does anybody replace their transmission oil filter when they pull the pan? I was thinking of flushing the AT this weekend and I was thinking that while I had the pan off, I would like to change the filter. Does anyone have any suggestions as to how easy it is to change and what filter to use?
Thanks.

I believe you have to replace fluid as you pump it out to prevent the transmission from burning up. It's kind of like you wouldn't drain out all your engine oil while the engine is running...therefore, you wouldn't drain out all your tranny oil while the engine is running.

Well...I just had a wild idea, but don't have the guts to try it.
Would the "2-bucket" method work if I were to use one of those pump devices that attach to your electric drill. You would then pump the new fluid into the intake hose while the old fluid is being pumped out of the output hose.
Any comments on whether this will work or not?
Ciao.

I happened to cut and paste someone's description from the old TS. Here it is (and it didn't work for me):
Probably the most thorough way of getting all of the old transmission fluid
out of the Tundra would be to drain the 4 or so quarts from the pan, then
disconnect the hoses at the transmission cooler in the radiator and let that
drain out, then re-install the transmission drain plug, then refill the 4
quarts (with new fluid) into the pan through dipstick tube, then connect a
transmission fluid flush machine to the transmission cooler tubes (or just
do the 2 - 5 gallon bucket trick), then start truck and flush out the
remainder of the old fluid while the transmission pump picks up the new
fluid from the machine (or bucket if doing that method). Once all of the old
fluid is out and all of the new fluid is in, reconnect the trans cooler
hoses and top off the transmission fluid level via the dipstick.

I change my fluid by draining the pan and then adding 4 quarts of Mobil 1 ATF every 15,000 miles. I feel sure this will be more than adequate even though I may never get 100% Mobil 1 ATF.

Well...I guess I'm not thoroughly convinced yet. I know we had a long, detailed thread in the "old" TundraSolutions that indicated that many members used the "2-bucket" method.
I guess I would like to hear from those same members as to what they actually did. I wish I could remember who exactly said what.
Come on people! How have you been changing your tranny fluid?
Ciao.

OK...if you drain 1, 2 or 4 quarts out of the hose or pan, and then add the same amount through the dipstick tube, doesn't the new fluid mix with the old? I.e., you would never have a 100% flush using this method...right?
Ciao.

Thats correct, you will never get to 100%, but you can get well over 90%. Which is probably adequate. If you are draining the pan hopefully all of the 'bad stuff' will have settled on the bottom and gets drained out.

Does yours shift a lot smoother when it's cold? Mine shifts like a dream during the warmup period, and then goes downhill from there.

The way i do the tranny is take the pan plug out and drain. next fill till dip stick shows full.Next remove the out flow hose off the rad that goes back to the tranny.Next get a longer hose and attatched it to the out flow on the rad. Next place hose into a quart clear jar.Next have someone start the truck and you watch the quart jar fill up , and then stop motor. Next add fresh oil down dip stick hole till full again.repeat this till clean fluid show comming out and then the whole system is done in twenty minutes.

Yep, I'll be doing some heavy towing, so I sprung for the 14 quarts of Redline.
I ended up using the methods described below (all new oil going in through the dipstick tube), but imagine my happiness at realizing that I have a big bucket full of $100 worth of oil that I now have to pour in a 0.5 inch diameter tube....

Trying to flush the trans using the bucket method on a toyota won't work because the return line from the radiator cooler is not a suction line it just returnes to the trans, the only pressure is from the discharge side coming from the valvebody at a specified pressure. The best way to flush the trans is have a shop do it that uses a transmission flush machine that will push the fluid into the trans at the same rate as it is discharged, as a rule this service will cost about 100.00 dollars more or less and should be done every 30 k under normal driving and 15- 20k under towing or severe driving. If you tow a lot or run your truck hard might think about going to a synthetic trans fluid like Redline or something like that, synthetics can handle a lot more heat with out breaking down and causing excess wear

The transmission pumps the fluid out to the cooler, but it relies on that pressure to return the oil to the transmission... in other words it won't suck fluid up thru the return line.
I exchanged my fluid by:
- draining the pan
- refilling thru the dipstick
- draining out about 3 quarts from the supply line
- add 3 quarts to the dip stick.
and I repeated this until I hit 14 quarts.
Hope this helps.

I didn't have any luck getting the return line to suck ATF, either. I pumped out two quarts, stopped the engine, added two quarts down the dipstick tube, and repeated this until I had the full 14 qt. flush.

Hi all,
I tried flushing the transmission fluid this weekend with the "two-bucket" method, but ran into a problem.
First I drained the pan (4 qts.) and added the 4 qts. of new oil through the trans. dipstick. Then, I disconnected the 2 hoses going into and out of the trans. cooler and placed each in a bucket. I started the truck to make sure I knew which hose the trans. pump would be pumping the old oil into. Once some oil came out of the "out" hose, I placed the "in" hose into a bucket of brand new oil to be sucked into the truck.
Unfortunately, after starting the truck again, plenty of the old oil pumped OUT of the truck, but none of the new oil was going in from the other bucket?
So, when I did my test to check which hose was OUT and which hose was IN, did I unknowingly add air to the system that prevented it from sucking in the new oil?
Thanks for any help.
