you fill it using the cold mark on the dipstick, then you take it on a test drive for say 20 minutes or so, enough to get the transmission fully hot, then you slowly add fluid up to the hot mark with car on extremely level ground, after stopping and shifting through the various gears, ending up in Park

I would then check it again in a similar fashion the following day, once again with it fully hot after an extended drive

try and not overfill it, though slightly overfilled will not hurt anything, and is preferable to underfilled
I have to admit that I have a really hard time seeing that fluid level on the stick... i mean that thing is as clear as water almost (especially with new fluid I put in). It takes me three of four tries to see the little shiny layer of fluid on the stick.
Is there a better way or at least a trick that will help me see it better?

you have to get it in the glare of the light to see the level, and it will often only be visible correctly on one side of the stick, so flip it over when reading

make sure to wipe the dipstick thorough dry beforehand

Are you sure that you have put the right ATF JWS3309 in the transmission?

I have done allready 2 drains and fills with mobil jws3309 but no problems here with checking the level.

Toyota Type IV. Compatible fluids are available as mentioned within the thread, for ease Toyota is safe and easy to obtain in most locations.

isn't the OEM trans fluid strictly Toyota T-IV whereas the power steering fluid would be Mobil?
Toyota doesn't manufacture any fluids, they buy them from the petroleum refiners, sometimes to an improved spec, sometimes not - Toyota T-IV is merely relabeled Mobil 3309 ATF that is just sold in a Toyota bottle. It's Aisin who specifies this fluid.

so if your Mazda or Volvo or Saab dealer has a better price, you can certainly buy your Mobil 3309 from them:

If this question has been asked before, please forgive me.

I'm considering purchasing a 1995 that has 16,000 miles. (Yes, 16,000.)

I realize that the advice is to do several drain and fills rather than than a single full flush, but would the low mileage of this vehicle allow a full flush right off the bat, or does the same advice apply to all transmissions, regardless of mileage?

Thanks.

Just did a recent transmission fluid and filter change and wanted to pass along a few things.

Though the transmission fluid on my recently purchased 2000 ls400 with 140k was nice and red, I wanted to change the filter b/c I was pretty sure it hadn't been done (got the filter along with quite a few other parts via the awesome and amazing Sewell Lexus site at a VERY nice discount I might ad). I also wanted to make sure the fluid is Toyota Type IV. The job is not that difficult, but there are a few things to know. First, the brace that runs beneath the front of the pan has to come down - 4 bolts, no prob. Second, be gentle taking the pan down - you do not want to bend the pan. I did have to gently tap a chisel or something between the pan and the transmission in a couple of places to break the original seal. Also, you will think that the dipstick tube won't come apart, but be patient, continue to wiggle it, and it will (I removed the mount up in the engine compartment - but I think this is unnecessary). Third, Lexus does not use a gasket between the pan and the transmission, but rather a red silicone sealer to mount the pan. I took quite a bit of time and cleaned all of that silicone off of the pan very carefully using a razor blade (a scratch in the surface can lead to a leak!) and finishing with a plastic kitchen scrubby. It took time but worked nicely. It was pretty much like new when I was through. Of course I cleaned the pan thoroughly and made sure the magnets were in place. I used a new drain bolt and crush washer I had gotten from Sewell Lexus. I've had good luck getting pans to seal in the past using just the gasket (no sealer), and I prefer this method as it makes the next change go infinitely faster. I did made sure all of the old sealer was gone from the bottom of the transmission as well (feeling with my fingers to make sure) before re-assembly. I re-assembled the pan to the transmission working my way around evenly tightening the pan bolts and careful not to over-torque them and voila ... no leak, no prob. Everything good.

I did catch and measure the amount of fluid that came out. I was a bit surprised that it was right at 4 qts - several post on this site state it should be about 2 qts. Maybe it's less if you do a quick drain and refill without taking the pan down. I will say, the fluid kept draining out of the transmission for awhile.

Hope this helps someone. This site has been a huge help to me. Thanks, all!
