How often to change tranny fluid?

We take our 2004 RX330 exclusively to the Lexus deal for all service, even oil and filter change. They tell us that the tranny fluid should be changed out every 15,000 miles. I think this is excessive, and expensive at about $100 a pop. Is this really necessary in this day and age when some car transmissions are sealed for life?

The Lexus Severe Maintenance Schedule is every 60,000 miles which should be in your owners manual, dealers sometimes make up their own.

Although that does seem excessive, I don't want to be the one to tell you not to spend the $100, and find out you had to spend $2000 or more because of it. What does your owners manual recommend? Let's face it, these transmissions of today sure don't hold up anywhere like the older transmissions, where you could buy a good used replacement for $300-$400 & get it installed for $200. Now your basically looking at a $2000 rebuild when it goes on you, if your lucky. If you don't go with the 15,000 miles, I wouldn't push it too much further, just because the fluid may be fine, but if the filter gets plugged & pressure drops, that can cause all kinds of trouble. Old story I guess, "Pay me now, or pay me later".

No, the average milage for changing the transmission fluid and filter is about every 40,000 miles.

2005 lexus rx330 how to change transmission filter

normally on automatic transmissions, the filter is changed by draining the transmission fluid & removing the transmissions oil pan on bottom of transmission. from there the filter is accessible.

some transmissions the filter are a metal screen to keep filings from entering the system, others are filtered through material.
trans filters for yours are available.
some pans have magnets attached to catch filings.
you may want to purchase a repair manual on your vehicle,( I have one for every vehicle that I have ever owned, they are very helpful) this will tell you the exact procedure for yours.

Same problem, jerking and slow to accelerate

Everybody knows that you change the oil filter for your engine and your engine oil. The one fact that most people DO NOT KNOW, is that this is true for automatci transmissions too. Yes, it is a little know fact by the masses that you should have your tranny fluid changed and tranny filter & magnets changed (if equipped).

For example, a few days ago I had a worried customer call me and tell me she could not afford a $1500 transmission. I assured her that the starting point wa to do a transmission service for her car. Her car did not have a tranny pan and tranny filter, so all we did was drain her ATF (automatci transmission fluid) and I noticed it was dark and almost even black. New ATF should be red like Kool-Aid. This was a sign this tranny oil was no good. I refilled her car and took it for a test drive. I was happy to find that the shifting had improved immediately. She was so happy when she got her car back.

Remember, you change your oil right? WELL, WHEN WAS THE LAST TIME YOU DID A TRANSMISSION SERVICE? Most people say "never" or " I don't think it has ever been done before"

Some people do this every 12,000 to 25,000 miles or once ever 2 years.

Do this and this will be your starting point. If this does not work (and this does work the majority of the time); then you may need to send the car to a tranny specialist and have the tranny rebuilt or replaced.

Good luck
