I have done a lot of searching and not found much info on the 6 speed closed transmission. I did find the PDF on how to check the fluid level.
Recently purchased a 2006. I'm in the process of making sure everything is in the best condition that it can be given its age and miles. The next project on the list is the transmission fluid. The car has 103k miles on it and has spent its whole life in the Atlanta area. The car must have been garage kept and only driven during nice weather. The underneath of the car looks like new. Even the bolts on the exhaust are rust free with only slight surface rust on parts of the exhaust. Always serviced at Nally Lexus. I suspect that this car was handled with care.
Do I change the filter and then drain and fill multiple times taking a chance that the fluid level might not be right or allow the dealer to flush the transmission? I don't trust dealers. I also don't trust doing a flush. Years ago I let a mechanic flush the transmission on a van I had and had nothing but problems after that. I might keep this car for a long time so I want to take care of the transmission which means the fluid has to be changed. Have Lexus do it or a transmission shop? Which Toyota fluid to use in an 06?

We do drain and fill. There's a lot of good threads on thus topic.
And yes, get it going ASAP to make sure your tranny lasts.

I believe the '06 uses the Toyota World Standard aka ATF-WS.
You can buy it very inexpensively from the dealer (probably cheaper than an aftermarket at Oreilley's)
While you are there, give them you VIN and they can verify that for you,.

2002 Toyota WS ATF for USAIn 2002, Toyota releases the Genuine ATF WS (World Standard) Fluid Specification (JWS3324 or NWS9638).[16][17] This fluid is not backward compatible with previous Toyota fluids or Dexron fluids. Almost all 2004 and above Toyota vehicles with automatic transmissions use the WS fluid specification. This fluid absorbs moisture and should never be reused. Always use fluid from an unopened container. See Toyota bulletin T-SB-003-11
Toyota asserts that under normal usage, the fluid has a 160,000 km (100,000 miles) maintenance interval for inspection only; ATF-WS does not require any flushing or changing during the life of the vehicle; however, an inspection of the maintenance schedule of many Toyota vehicles reveals that there is a 100,000 km (60,000 miles) replacement interval if the vehicle is used on short trips, city driving, hauling heavy loads, trailer towing, or using a car-top hauler. Check your own maintenance schedule for your vehicle's requirements.

My "new" 2006 SC-430 has 178,000 miles on it. I thought about doing something about the tranny fluid. But it is shifting so smooth and running so well that I am afraid to touch it. The last time I had a transmission flushed it was a Cadillac Seville and it never shifted right after that,

Agreed, but maybe do it incrementally via multiple drain and fills over time vs a flush. With this many miles, it is risky to flush. A drain and fill only removes a fraction of the total capacity, so you are less likely to have negative side affects.

But I also agree with BGW that the mileage has most likely killed all the stuff that makes it Transmission fluid.
On my Pontiac Vibe (aka rebadged Toyota matrix) I did a Wilson and drained the pan and refilled with two quarts of fresh fluid. Instead of the dipstick being black (like it was) or red (like it is when new) mine is an odd shade of Purple. Been about a year and so far so good. I think I am going to replace 2 more quarts in a few weeks.

I agree with you. Changing Transmission Fluid for the first time on high mileage cars always seems to cause problems. I heard it was because the seals start to crumble when u flush the system.
