Doing the drain/fill with 8 qts of Toyota WS, how long do I run the engine after first drain fill? 30 seconds or a few minutes before the second drain/fill?
Thx

I believe the drain and overflow use same ATM gaskets 35178-30010
The fill uses the other, correct guys?

I have only done this on a GS350, but same procedure. I replaced all 12 quarts, 3 at a time. Ran less than 30 seconds after refilling 3 quarts each time. Shifted through the gears and cut it off. Drained 3 out and filled 3. Repeated until came out cherry red.

Thx, I better get 4 more qts, does it cycle or move the fluid in the pan that fast?

I am planning a 9 qt drain and fill (3 qts 3 times)
Can anyone tell me how long it takes for the new fluid (3qts) to cycle out of the pan, 30 seconds of engine running is correct?
After 3 d/f's I have 1 addl qt to add before putting in checking temp mode
Thx

are there just 10 quarts in the GX470? My GS350 sedan had 12+ quarts with the top off.

30 seconds will be enough to pump it out of the pan, but you will be way better off to drive the car around the block 1 time or so to make sure you are draining out the maximum quantity of old oil.

Drive around after each 3qt fill or at the end of 3 d/f's?
thank you

In between each drain + fill.
It lets the gear changes run the newer fluid run through all the passages.

Thank you all

I'm sure you could accomplish the same thing with the truck still up on the jackstands. 3 drain and fills, where you need to be careful to have the truck sitting level, and you need to have the truck up on jackstands becomes a much bigger job when you need to lower it off the jackstands, drive it around the block, and jack it up on stands again in addition to the rest of the work.

I'd just run it through all the positions on the gear selector between drain/fills if it were me, leave it up on jackstands till the job is done, and call it a day.

Yes, but my method is safer, and lets the fluid come up to temperature because it's under load.

That's true, but no shop is going to do this extra step if you had them do a tranny fluid change for you.

After several posts and consideration of doing the change myself I decided to have the dealer flush the transmission. It was $500, 5hrs and 17 quarts transmission fluid. The time required was necessitated by the various temperature checks and cool down periods. I have only driven 40 miles of freeway and town driving but I am going to be honest – the car seems more responsive. I drove the car from the dealer and thought the throttle seems more responsive. It was like a tune-up in the old days with new points, plugs and a carb rebuild. I was hesitant to mention this but I will get more miles and see if it is illusionary or actually different. Maybe I just want something for my $500 and if that is so the mind is really remarkable. I went from no way am I am doing this to why did you wait so long?

I called a number of dealers and transmission shops here in Seattle before doing this. I got everything from don’t do it to just drain the transmission. It was surprising how conversant they were about the transmission. I have to say the dealer price in Bellevue set me back at first but then I spoke to the service department and they explained the process they use and the fluid cost. Ok, I got it why it costs what it does – darn it. I am always nervous when something seems to get peppier. It reminds me of the lawn mower that has a spurt just before it runs out of gas and dies.
Now, do I do the shocks? $1,500 of pain or $1,500 of endorphins?

I asked a local Lexus dealer for a quote on replacing the transmission fluid(I was just curious bc I have done and will continue to do all the work on my cars myself) and they told me that these cars do not need to have the fluid changed, "It's a lifetime fluid and even if you wanted to change it you can't bc it's a sealed unit."

I replied, "Huh, that's cool I guess."
