Video clearly states: This episode demonstrates the proper method and tool needed to check the automatic transaxle fluid level of a 2007 and newer Aisin U660E/F or U760E/F 6-speed automatic transaxle. Not AA80E.
Just watching the video - none of this is documented for the AA80E in TIS. There is no removable tube in the oil pan on the AA80E, we have separate drain and level check ports on our oil pan. I get why this is available for these Toyotas as they are the most common Toyota platforms on the road, but our gearboxes are pretty rare in the grand scheme of things, and have nothing documented for a hot fluid level check.
Yep. Just finished watching the video. Not even a small chance this works for our gearboxes.

OK, but that doesn't meet the factory's requirements. There are lots of things I can do that don't meet factory requirements, but this is one I wouldn't think about short cutting only because I know what happens when the transmission is as little as 4 ounces short.

Thank you for confirming First time dealing with a “sealed” transmission but I figured what he was saying didn’t sound right to me lol.

I went ahead and drained the pan, replaced the filter, replaced the gasket, cleaned pan and magnets and put in 6 quarts of ATF and then set the level using the car ATF temperature mode.
I have no idea if its in my head, but the car seems to be accelerating quicker and seems to have more power.
It doesn't lag when downshifting now and when I take my daily trip in a round about, coming out of the round about on power the car doesn't hesitate like it used to.
I did not measure the quantity of fluid that came out, but the stuff that came out was dark like slightly used motor oil. (2008 - 66k miles)
When I set the level, it appears that about .5 Quarts came out before it began trickling.
I also flushed the brake system while it was up on jackstands...the 3 year old fluid was the color of morning urine...yuck.
I also noticed the differential bushings were starting to look a bit worn, will have to keep an eye on that in the future.
Thank you to all who posted in this thread!!

No sealant needed. The gasket is really thick and has metal collars where the bolts go through so you can't make the gasket extrude from overtightening. Sounds like 6 quarts is the magic number too. I put close to that in mine and figured I was about 5.5 quarts with the pan drop and filter change. I wish I could say mine drove differently, but it doesn't.
AFA fluid - I am planning to try Valvoline Max Life on my next oil drop. It claims to be fully compatible with Aisin WS, and it's available at Wal-Mart for a decent price. I originally bought a case of WS from the local Toyota dealer for $110 (case price), but it is nearly gone, and I have no reason to believe the Valvoline fluid will cause problems.

After reading through, I might give it a try. I've been looking to see if anyone finally chanced to use a Non- OEM ATF fluid, I know my friend Jason has used Redline D4 I believe in his transmission ( Replaced 8 qts) and it worked fine. Let me know how it goes, I was going to plan to use the same stuff you are using.

I had a bad experience with D-4 in my Supra. I wouldn't run it again unless I had a really compelling reason. Too much seal swell in it for my taste.

I didn't do mine until nearly 150k miles.

Probably, but you still need to row through the gears to actuate all the solenoids. You just won't be depending on the flashing P sign.

Here is the analysis for my 2008 ISF. This is the first sample that was taken. I had the dealer (Lexus of Cool Springs - Tennessee) go ahead and drop the pan, replace the screen, gasket, and the fluid that was lost during the process. They set the level and were very very good about everything. The total cost was about $400. My car does shift noticeably better now that the level is set, to concur with the others who have undergone the level setting procedure.

I had my pan dropped filter changed and refill 4 quarts yesterday at 58000 miles at a shop that performs some of my maintenance. I was under the impression they’d change all or most of the 11 quarts.
So I called Lexus and they can flush and drain all 11.
I know many many don’t even feel changing it this soon is necessary. None the less, does anyone know if this flush is the real deal? That is, will they change all 11 quarts.
Imo it’s good maintenance if their descripton is accurate.
Thanks for any opinions
