ATF capacity per dipstick marks.
After doing extensive work on my 96 LS400 recently, my ATF level's down a bit. After a freeway drive, I checked the level while idling and it was just hitting the bottom of the "hot" section of the dipstick.
I'm still relatively unfamiliar with this vehicle. Does anyone know about how much T-IV will get from the bottom to the top of the hot section?
I ask because I'd like to top up before work and drive the car tomorrow, it's late now, and properly checking the level and filling bit by bit till I'm familiar's a little cumbersome.
Thanks again, team!

I feel like one fill quart is quite a lot from the bottom of the hot range to the top of the hot range.
Why not just not bother figuring out how much it takes to move a fluid up a certain distance on the stick and just add fluid a little at a time until it's where you want? Better than overfilling.

It was a time constraint thing, Banshee. It would have taken multiple drives to get it perfect. I erred on the side of caution and tossed 1/2 a quart in there before my drive to work. I'll check the level when I get home and we'll see...

Multiple drives? Add some, check it, add some, check it. No drives required, it just has to be running.

Wouldn't this be noted in the owners manual? I believe the oil change information regarding the upper mark and lower mark is, but I can't confirm that that the transmission marks would also be there.

I checked my 1991 owner's manual quickly, and there is nothing about it being one quart or liter between marks. Also, the figure in the owner's manual shows a much smaller gap (like 2/3 as big) on the dipstick for the cold range vs. the hot range.
If you want to calculate how many mm one liter should add to the dipstick level reading, you could just divide 1,000,000 mm^3 (volume of a liter ~ quart) by the area of the AT pan (in mm^2). So if the pan is 30x50cm (just a wild guess), then the answer would be 6.7mm, for example.
Or you could just add a little at a time.
BTW - I just checked the owner's manual for the oil dipstick to see if it actually said one quart, and it did not. Same as for ATF, it just says to add a little at a time and re-check. It also shows the dipstick, and apparently the Low and High range is actually specified by the cross-hatched region in between the L and the F, and NOT the L and the F letter, or the lines outside those letters.

I agree, I believe the engine is more tolerant to oil level, so the standard thing that most cars do is to make the distance between the marks one quart/liter, mainly for convenience. But ATF seems to need more precision in most cars I'm familiar with.

Just for the record, if you're at the very bottom of the hot mark when the engine and transmission is at normal operating temperature (a good 10 minute freeway run will do), add 30 percent of a quart to hit the top of the top mark.
1 quart would put you into solidly overfilled.
So Banshee was on the money again.
