Auto Transmission flush or no? 03 ES300

Have you tried Castrol Transmax Import for Toyota? If so, what were your thoughts?

Get 4 or 5 qts of T-IV, Mobil ATF3309, or Idemitsu TLS. I believe four are enough for a drain/fill. Unless you think there's a lot of clutch debris settled in the pan (unlikely unless the car was abused), then dropping the pan is not necessary and I wouldn't get a gasket, either. I did eventually change my gasket at ~300k miles when it was weeping a very small amount (not enough to even leave drops on the driveway). The pan was spotless. The strainer was - well, just a strainer and I examined it to make sure a thrust bearing wasn't broken up in it, but otherwise didn't touch it.
I would also recommend buying 1 or 2 transmission magnets as well to put into the bottom of your pan.

It was $7/qt from TruTrans, sometimes I find it cheaper and stock up. It is a great substitute vs. MaxLife if you have a newer Lexus/Toyota needing WS. Also great for problematic Honda trans. or a Dexron vehicle. But it's more expensive than the best stuff for these cars so I haven't tried it or felt the need in using it in lieu of T-IV/3309.
Summit racing has 6 x qt containers of Mobil 3309 for $30 - as cheap or cheaper than MaxLife, this, or most any other "substitute" fluid for these transmissions. They have very fair shipping and free shipping at some break-point. So just no reason not to use the real-deal when it's as cheap or cheaper and works better.

The strainer is not a wear item. It's not a paper filter that clogs; it's just a cow-catcher device to grab out chunks. Don't waste money replacing it.

This is not a bad idea when the pan is open. I *think* these pans had magnets in them and a magnetic plug - more than enough. On my SUV, which had neither, I put magnets in the bottom of the AT pans (yes, it had two). I would not open the pan on the ES just for this.

I have also seen owners mess up their transmission (when a moderator at TN) switching out the metal and installing the cellulose - starved the pump. The bottom line is to match what's inside and it's not consistent against all U transmissions and years.

The picture I posted is from a 2003. Yes of course use what came from the factory but don't say the filter is a screen when it may not be. BTW my 2000 has a felt filter not a screen.

Seems reasonable to replace it at 191k, though I understand some prefer not to mess with it

Ummm.... be careful what you buy online and make sure the filter/strainer is a Genuine OEM Denso product. EBay and Amazon advertisers are some of the craftiest, wordsmithing retailers of fake parts in the market.

That's fantastic advice; you should follow it.

Here’s the inside of a ‘98 IS400 transmission fluid filter/strainer.
Clearly a screen.

But, if you’re going to do a drain and refill/filter change instead of a flush/filter change, consider this... Get a 12 bottle case of Denso T-IV ($75 online) and do two drain-and-refills, then do a drain/filter change and refill for the last one. I found it somewhere and posted it here a while back that this procedure will give you roughly a 65% “flush” of old fluid and tranny slush vs a full flush and you’ll be able to clean the pan and magnets. You’ll likely rid your transmission of a lot of slushy muck there also. Do other single drain and refill jobs like every 3 - 4 months. Your transmission will love you for it.
Drive about 30 minutes between changes and include a fair number of stop-and-go maneuvers to accelerate thru each gear. The fluid will be hot, so remember that when draining.
Cheers

Good idea to take responsibility of it yourself (theOP). It will be done more competently and carefully, and you will know exactly what happened. I took a Honda Civic to the local Honda dealership two weeks ago for the Takata Airbag recall. They also had to replace the seat belt buckle on the driver's seat for the sensor. They screwed up re-installing the seat and now it rocks like a deck chair on the Titanic. I know it was perfect before it went in because I personally had fixed it the week before (this gen Honda's are known for this fault). Even the dealership couldn't get it right...

2 x d/f will get you to 60% clean fluid. 3 x will get you to 75%. Since it was last d/f'd "only" 60k ago, I'd be ok with the 2 d/f's for 20k then I'd do it again, then every 30k after that. I have been running either T-IV/3309 or Idemitsu TLS (same) for quite a while now. I am finding 30k to be where the switch from old to new fluid is barely noticeable. The other reason I'd do it on the OP's car in 20 as then it is at 210k, and he's on the multiples - every 30k - 210 (7x30), 240 (8x30), etc. It helps me remember (that and a 200-line excel spreadsheet of all service back a decade!).

I still do advocated 9ozs of of Lubegard Red into the case on the last d/f, and 1 oz into the PS res after d/f'ing it twice. Or better yet, d/f it with Lubegard PS fluid. It has kept my seals and hoses intact (problem on these cars) and they are still original and not leaking at 315k.
