No I haven't done the test that you mentioned. So I just loosen the cooler line and see if it sprays out? I need to do some research before I do that I guess.

oh well, if the two tests test the same thing I will choose the less messy test. I was hesitant about disconnecting lines anyway. But I haven't gonna around to actually doing this test anyway. Tomorrow I should do it.
Thanks!
Thanks!

BUT: you would remove the line, put a rubber hose on it, put the end in a bucket to catch the oil and THEN start the engine... this is also a good way to "change the ATF" in your tranny, instead of just 2 quarts at each oil change....
Oh, BTW, I retired 17 years ago (96) and had only owned 1 LS400 at that time, and we had never had one in my shop either.... for whatever that is worth..... I should probably just read and not comment.

I am looking at transmissions on ebay. http://www.ebay.com/itm/98-00-TOYOTA...-/390560518809 This one in particular, I am looking at.
Anyone have experience with transmissions like this? Are JDM engines and transmission the real deal?
Does anyone know what it takes to switch a transmission out in a vehicle like mine? Do I have to do much after I install a new one? Like software updates or have it calibrated by the dealership?

I did the test of the transmission fluid, with engine off and engine at idle. I didn't notice a difference in the levels. I idled the engine for a two or three minutes. Then check the fluid level on the dipstick.

then your problem is TC/front pump, call a transmission shop that works on toyota-lexus.
their price will probably blow you away....
the ebay looks like the way to go.... but someone smarter than me needs to tell you,
have you tried craigslist??

some aftermarket transmission filters have a habit of falling down into the pan, making it now impossible for the fluid to get picked up and delivered to the pump, giving this exact same symptom of no fluid pumping - definitely change the filter to a genuine Toyota before doing anything else. - this little tidbit may just save the OP and/or the towing company a couple of $1000
let's hope so!

So you would definitely drop the tranny pan and check the transmission filter? I am close to taking it into the shop, but normally I do all the work on it myself.
If i drop the pan on the tranny, how much oil will come out? I am not sure I have a large enough pan or bucket to catch it all.

Has anyone on here actually replaced a tranny in a car like mine? Been searching the forums and can't find much. Not sure if there are any tutorials our there.

The first thing i would do is a fluid and filter change. When i first bought my car it had been sitting for over a year and still ran great but several times the trans quit pulling and after waiting 5 mins or so and recranking it would pull fine. i have a habit of doing a fluid and filter change on the trans first thing with any used car i buy. i also recommend putting a quart of Lucas additive and high quality fluid in. i changed mine and also used the Lucas Automatic transmission fluid too and it has pulled perfect ever since. my fluid didnt look bad at all but the screen in my filter was almost completely blocked. i would change it before doing anything else. it will cost you about $50-60 bucks and it is more than worth a try. i have seen it save many transmissions. Changing the trans fluid and filter is actually a regular maintenance but most people over look it. Good luck to you

So it has been awhile, but I am still working on the problem. I got under the car while it was running. I removed most of the shields, especially the one showing part of the fly wheel. The fly wheel is turning, but there is a lot of racket coming from that area. It is making a lot of rotational noise, and racket. To me that would seem to make a broken torque converter more of a chance.
I got a transmission jack and am thinking of just dropping the tranny. Hopefully I would find the problem that way. My reservation, is what if it is some electrical sensor or maybe a tranny solenoid issue.
I am still working on the problem and welcome any advice on the matter.
