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.

 

Can this procedure be done on a 2000 es300 and where would the cooler lines be on the 1MZFE engine. Would it be the same location as the LS with blue clamp.

 

Is the procedure same with 2006 LS430?

 

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.

 

I've heard it's bad to flush the tranny fluid... true? I need to know, my Lexus has some pretty dark fluid.

 

It's not bad when you do it this way. You're just running new fluid in the system the way it was intended, you're not using a pressurized system or back flushing.

 

Is that the hole for the transmission fluid?

 

Thank you for this DIY tip. I've forward this link to the SC430 section as well.

 

Its the hole where the transmission fluid dip stick is located. I would only assume this will work with the 5 speed tranny. The 6 speed tranny does not have a dip stick.

 

Can someone tell me which pipe to remove?

Pipe A or pipe B?

 

I believe it is "A".

 

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".

Right. Unfortunately, he's correct for an LS430 from MY 2004 - 2006. They're filled with Toyota WS ATF at the factory and they're not intended to be serviced. The T-IV fluid found in previous model years definitely requires service.

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.
