is there a trick to this
i want to accurately measure the atf level in my 99 rx300. however, when i try this with the engine running, i see fluid going almost 2/3 of the way above the "correct hot level" mark. this was filled by the lexus dealer some time ago, and i can safely assume the level is correct. also, the tranny works great. however, my curiosity calls on me to measure the level myself. how do i do this???
i carefully wipe the whatever you call it [the thingamajig; dipstick] and insert and withdraw. am i missing something??

Checking the ATF is a pain in pretty much all cars, well that is unless the car shows the level on the info screen. lol
That sounds a bit overfilled. Mine is a bit higher that where the hot mark is. I know Lexmex runs his where the dipstick says "T-IV".
I'd drain a tad bit out, or just go ahead and do a full drain and fill.
The proper procedure is to leave the engine running car in Park, after driving for 15-20 minutes. Then pull the dipstick, wipe it, re-insert and pull it out again to check the level.

I have never been able to make a good read.

That's the best way, done about a half dozen times for good measure. LOL My feeling is, ONCE you are sure you are at the right level with it warm and running, as it should be, when it is cold, check it on LEVEL ground and mark that on the stick. From then on, CHECK IT COLD!

* I understand. "My" RX belongs to my daughter, and I simply maintain the fleet. I'm headed off to visit her at college next weekend, and I'm going to change her PCV valve -- one thing I forgot to do before she left. I had to find wrenches shorter than 7" to pass through security in my carry-on.

My 2c:
Expansion of material happens with heat (exception is Water at certain temp) but in xmission case I think the issue is due to circulation and heat and not just the heat. [the amount of difference is a bit too large.
IMHO once the transmission is hot, you should not use the hot level with engine OFF.
No fact .. just hunches.
