I can't understand that. You drive how many miles every year and spend how much money on fuel, but are looking to save $20 on the fluid that will keep your transmission functioning well for many miles? It is just a disconnect for me. If you need WS fluid, buy WS fluid. If you need T-IV fluid, you can buy it at the dealer or use Mobil's JWS 3309 fluid, which is exactly what your transmission needs.

If so, the owner's manual says to use Dexron II or III. Is there a particular brand for type 1 engines?

If not, any opinions on putting in a new transmission on a reliable vehicle with so many miles already on it?

Thanks for all the feedback, photos, and info provided here.
I would try the drain and fill first. It won't hurt and is a lot cheaper than just spending $2500. Use Valvoline max life.

There isn't a filter, it's referred to as a strainer.

Re: Automatic Transmission Fluid

Hi everyone. I have an 04 sienna w/ 189k on it. Starting to feel a slight bit of shift delay in the lower gears, maybe 2-3. It almost acts more like a modulator problem than a fluid problem. Like when your coasting then resume with the pedal it has to shift. Its so faint my wife who drives it daily can't feel it. Anyway, I pulled the dipstick this weekend and the fluid is a Lil dark. Not bad at all for what Im assuming is 189k mile fluid. I want to change it but I'm kinda skeptic with that many miles on the odometer.
I would ask my dealer but Im stationed in Germany. They are still great guys at the local dealer. But I have a hard time communicating with them. I can ask them what they think about changing it. But what I can't differentiate is the difference in "should I change my trxn fluid?" Or "will you change my trxn fluid?" The basics he will get is that I want the fluid changed. What I really want is a second opinion. Anyone got any feedback they wanna share?

Re: Automatic Transmission Fluid

Change your fluid. It can only make things better. Not sure what you can get in Germany, but I think Toyota Type IV should be available.

Re: Automatic Transmission Fluid

Hi Everyone,

I have a Sienna '04 XLE AWD with about 100K miles (163K KM) on it. Checking the Transmission fluid dip stick for oil color, it was found to be very dark, almost black. I have not noticed any abnormal thing in shifting but concerned with the color.

I understand it uses WS type oil (still need to confirm from the dip stick embossing) but not sure if the healthy color should actually be a dark reddish shade rather than the black I see.

The vehicle history I got from the Dealer (from Toyota database) mentions twice something about "Trans" oil/fluid change. 1st @ 45K miles and 2nd @ 83K miles.

I am not sure if this reference for "trans" means Transmission or Transfer case.

Appreciate if somebody in forum can suggest what is best to be done at this time?

Thanks

Re: Automatic Transmission Fluid

The mileage you have on your 04 XLE AWD is the same as my 06 XLE FWD. I did the transmission fluid change twice roughly the same mileages as your vehicle. But both time my transmission fluid was pink (close to original color). I don't know if the previous owner might tow a lot with the vehicle. I would change it out if I did see mine turning black.

The correct fluid for your 04 is T-IV

Why do we have to do the drain and fill when the engine is hot? Wouldn't it be easier and more accurate to drain when it is cold, measure quantity, and refill with the same temperature fluid that is "cold"?

Also- what is the correct fluid type for a 2005 sienna awd?

Thanks in advance.

The 05 also uses Type T-IV.

Toomanycds,
I'm getting the same P0770 error on my 1999 sienna. Did the drain and fill AT fluid help? My smog is due in a few weeks and with this problem it won't pass. Any feedback/comment is appreciated.

Re: Automatic Transmission Fluid

tonystewart, a couple of questions!

1. Have you done any more oil analyses since starting the thread?

2. Do you still stick to one drain / fill every 24k miles?

Re: Automatic Transmission Fluid

I have a 2005 XLE Limited AWD and it has 200,000 + KM and only changed the ATF once done by the dealer. My question is has any one ever changed the oil via the dip stick with a suction pump like used on inboard and outboard boat motors ? Not sure if it would work but it sure as heck works well on my boat motors and very simple.
thanks, Pete
