Hi all, I'm looking to replace my transmission filter and was wondering if someone have the instruction from the service manual that they can share with me. If no data from the service instruction manual is available and someone has done it before, please PM with the info or you can explain it here if you would like. Thanks.

No one knows anything about this??? I'm sure some of you have changed out the tranny filter before...

Yah know.. In almost 5 years of owning my IS300, I have never had of a tranny filter for our cars...

If its in there, its probably a "non service needed" part.. just like our gas tank filter...

Can anyone else add light to this question??

Thanks

I've had my car for a while now and with almost 50k miles on the clock. I was going to change it since I will be flushing out the old fluid and installing a tranny cooler and stuff. So if someone knows anything about this, I would really like to know too.

so do you want to know how to change it or if you should.

To change it, you would:
1. drain out all the oil from the transmission pan. There is a plug, very similar to the engine oil pan.
2. After it is all out, then you would begin to remove the pan. I can't remember how many bolts it is but it is alot. If you have an air ratchet, get it out. Once all the bolts are out, get a flat head screw driver and pry off the pan. There is no "physical gasket" on the pan, it is actually made up of slicone. Get a putty knife and scrap off the old slicone, both surfaces should be completely clean before reinstall!!!!. Keep in mind, you will need new slicone to reseal the pan. (You can get it at your local auto parts store, make sure you get the import one)
3. Once the pan is off, look at the transmission. You will see the filter there. It is held on by 1 screw. Unscrew it and remove it. You should be able to tell the condition of it just by looking at it, since all it really does is hold any metal shavings to prevent from flowing thru the tranny. If you have alot of metal shavings, you should have your tranny inspected, cuz that's not good.
4. Replace the filter, (just get the one from Lexus, as there is no such thing as a high performance filter for the tranny)
5. Make sure you apply silicone on the pan before you reinstall it.
6. Begin to bolt the pan up, start with the four courners, then add a bolt in an X pattern so the silicone will spread evenly. Or you could start with the center and X pattern it going out...this way makes more sense to me.
7. If you have not added the plug, add it.
8. Refill your tranny fluid.
9. Thats it. It should take you about 2-3 hours depending on your skill level and the types of tools you are using.

Also don't forget to get the fluid hot before doing so, like driving the car for a while.

Wow, thanks man for the info. If you don't mind, can you tell me if the filter is located towards the rear of the pan or to the front?? i.e. location. The reason I decided to change the transmission filter is because I will be installing a transmission cooler along with a external transmission filter therefore I say what the heck, I might as well change the filter in the transmission itself to be safe.

I wouldn't try getting the fluid hot like you say. Hot fluid coming out of the tranny will more than likely take the skin off of your hand. I say, let it warm up slightly..

Check the shop manual for me to be sure if you don't mind. And pin point the location of the filter to me for exact reference so that I don't have to be deciding which one is the filter. :p

i just called my dealer and they told me that the tranny filter is a stainless steel filter and does not need to be and is not recommended to be changed on all lexus vehicles. true or false?

Took mine out to do a valve body upgrade recently. In my opinion, it doesn't look like it needs to be changed. I really have no idea why its even there in the first place. Any shavings from the tranny will be caught by the magnets on the bottom of the oil pan.
