DIY For Transmission Flush

I don't know if there is suction on the unhooked rubber hose. My thought was that the pump pushed the fluid through the lines. I tried pumping out two quarts the first time and I got some gurgling at the two quart mark. I had my son turn the car off because I didn't know if there was only two quarts in the pump and I had started to run it dry. I only pumped one quart at a time afterwards and it worked fine.
If there is suction your idea would work. However it might be tough juggling two lines at once. Remember if there is suction you have to turn the car "on" to get it and when you turn the car "on" the other line will be pumping out fluid. It might be too cumbersome unless you had all 8 quarts of fresh fluid in a container and pumped the "old" into another container while sucking the "new" into the system at the same time.
There is Type IV fluid on the market other than Toyota. I think I paid $4.25 a quart at the Toyota dealership. You'll probably pay over $3.50 for another brand anywhere else. I figured for the extra $6 it was worth it to use OEM fluid.

I have a small leak on my LS430 transmission pan. I've tried to order the pan gasket but couldn't seem to find one. I've also heard there are no gasket in transmission oil pan for the LS430? Could you elaborate on how to "reseal the pan"? Thanks.

Tranmission Fluid Changes on 2005 LS-430
There is NO TRANSMISSION DIP STICK on my car.........I"ve said it 10 times. My friends are Lexus Tech's, and they say "LEAVE IT ALONE". Gawwwwwd. Go buy a Chevrolet and be done with it.

Yes, take it to the nearest Lexus Dealer and tell them to "Fix It".

Some units, like those found in the 2IS cars don't have a heat exchanger in the radiator - they actually run coolant all the way to the gearbox, so you couldn't change the fluid no matter how much you'd like to unless you remove the pan, and this only changes 2 liters of an 9 liter system. Hardly worth the effort.
Add to this a rather PITA procedure for setting the fluid level after you've monkeyed with the thing Lexus very specifically says to leave alone, and it's even LESS worth the hassle.
So, if you want to persist on changing your oil every 3k miles and your ATF every 30k because it worked in dad's '57 Chevy, be my guest. I'll follow the engineer's recommendations (not the tech's recommendations after a few beers at the bar) because the guy who designed, built, and tested the unit probably knows a whole lot more about the gearbox than the tech who is working on it.
I haven't owned 30 cars in the last 10 years. I'm not running a used car lot. I have however done a lot of work on motorcycles, cars, and aircraft. I'm also one of a very few Supra owners who has rebuilt his own Getrag.
I'll take Lexus's word for it. It a lifetime fill.
And yes, the 2IS forum argued all the same arguments I've seen here.
