Tranmission fluid flush? Help guys!

I have a 2006 IS350 with 98k miles. I have always changed oil & filter every 5k miles. I have never done a transmission fluid change. I took it to my mechanic and he said there is no dip-stick and he belives the tranmission fluid dosn't need to be changed because it is for lifetime of the life of the tranny. Please advise us. I looked in the owners manual and it does not talk about tranny fluid at all in the maintenence schedule. The dealer of course says it needs to be done every 30k miles. Which i belive is probably overkill.

It doesn't get replaced, ever, unless the system is opened or your car follows in the "severe use" category(ie. towing). There is no lexus service interval to change the fluid as mentioned. If the fluid is replaced, it is injected. I would not worry about, but you can have it replaced if it makes you feel better

Also i'm going to complain to lexus corporate. Tustin Lexus shouldn't be telling all their customers that something needs to be changed if it dosn't need to be (unless under severe use) Which 99% are not.
People go to a dealership for service for honest and expert work on the car. Not so the sales man can screw over a customer for work that dons't need to be done.

No, I believe there is no regular service for the differential as well, but it can be done(see second link).

The fluid needs to be injected or pumped into the transmission if it needs replaced. Check this thread out.

Up until a year or so ago it was physically impossible to change the transmission fluid on an automatic 2IS

Even dropping the pan entirely only removed 10-15% of the fluid in the system, so there was no way to change most of it.

You can't flush the system using the cooling lines, because they don't contain any transmission fluid, they contain engine coolant that runs to a heat exchanger built into the side of the transmission.

A year(ish) ago a company that makes fluid-exchange machines came out with an adapter in the exact size/shape of the heat exchanger though.

So it can be done now, but it basically requires the following:

Disconnect coolant lines
Remove heat exchanger from side of transmission
Replace it with this adapter
Attach fluid exchange machine and swap fluid
Remove adapter
Replace heat exchanger
Reattach coolant lines
Replace any lost coolant
Refill transmission using overflow procedure (since there's no dipstick the only way to refill is basically add fluid until it pours out the overflow hole)


Lots of work for a procedure the owners manual explicitly states is never needed.

another way you can do it is by

1- draining out the fluid. then close it back up
2- disconnecting the feed line from transmission to radiator. ( test it by pulling one starting car for a sec if it squirts its the feed if not use the other. there usually next to each other
3- put send line in dump bucket
4- refill transmission and start car while car is on it should pump out fluid ( keep filling none stop while its pumping out old fluid.
5- after the transmission fluid coming out is bright red turn car off. check levels and top up if needed.
