04-06 Sealed Transmission fluid change interval? (The Mother thread)
#106
Never ever flush a Toyota tranny, ever. Some dealers offer the service because BG sold them a nice machine that does it and they get a nice profit from it. Flush moves stuff around in there that you don't want moved around.
Drain & Fill is the ideal option. It removes a large portion of deposits as they end up in the pan, the metal shavings are captured by the magnet in the pan and stay there. So then adding even a small portion of new fluid replenishes anti-wear agents which is the key to longer tranny life. If you absolutely must do this yourself.: for the World Standard fluid transmissions make sure you can get the fill plug out first, you'd be amazed how many drain first then can't get the fill plug out. Get a container with measured lines on it and drain the pan into that, car needs to be cold, using the measurements on the container, add the same amount of new fluid to the transmission. This needs to be a precise measurement, don't just "eye it". You'll need some sort of a pump to get new fluid into the tranny. Somebody probably sells one at parts store, not sure. Do this about every 30k miles. Get the fluid at a Toyota or Lexus store.

Do you have acess to a lift? If not make sure the car is raise on all four corners so the trans. pan is level when drain and fill. Make sure you have enough space beneath the car to go in and out; and take out the fill plug first, on the side of the trans. You don't want to have all trans fluid out already and can't loosen/taken out the fill plug.
When fill, put the rain plug back in and take the over flow plug out. Fill fuild until the fuild come out of the overflow, then you are done. There are a few more steps but don't know you are ready to take on this task yet...

Yeah its like the Prius and Land Cruiser..
I did a drain and fill, and then did 8 litres through the cooler lines, this latter bit was really really easy.
I was filling via a 5l container with an air line going into the bottle. Fluid just shot straight into the transmission, 2L took about 30 seconds so it was really easy.

Lexus says 04-06 has "lifetime" AT fluid. But gives absolutely no definition anywhere on how many miles is lifetime. I plan on doing a full AT fluid replacement on my 06 LS at 50-60k miles. Dealer cost to do this is about $200-250.

i had mine done at a toyota dealer at 83k miles. i have a wholesale account on parts so it cost me $89 for 12 qts of world trans fluid.it cost me $90 labor to change the fluid after my 10%military discount.
i can tell after the fluid change the trans shifts smother and shifting from drive to reverse is also smother.money well spent.

Today I called a reputable indy tranny shop that only works on high end cars. The owner, who's been in the business for 30+ years, emphatically told me NOT to consider either a flush or drain and fill on my '05 LS430. He said that the cars are delivered with a very high quality fluid which should last the life of the car. Regardless, why would introducing fresh fluid be bad? Among other things, in his opinion the DETERGENTS in the new fluid are likely to cause problems. This guy has never seen a problem with an '04-'06 LS430 transmission. He ended by saying, "If it ain't broke, don't fix it!"

Use common sense folks, don't blindly believe what some people tells you, no tranny fluids last forever

I called my SA to get his advice on the fluid change. On 04-06 models the dealership's SOP is to inspect the tranny at 100K miles and to change the fluid if warranted (which I'm sure is usually the case). The fluid change costs $225. I'm booked for next Wed.
