    That too has probably allowed or helped this XC to go into whatever it is doing
    Look, it's never been serviced. To get over 300K miles out of it is a friggen miracle!

    Just shop for a used transmission or if you have a QUALIFIED shop near you, rebuild yours, but I caution that the case itself may be too (internally) worn out to even do that!.

    (I've come across several of these, with less miles than yours, that could not be rebuilt)!

    310k miles on a 2004 car means a lot of highway miles. Where transmission sits in fifth gear with locked torque converter and ATF temperature at about 170F. No shifting, steady load, cool ATF, why it should go bad?

    City traffic is what kills it. If it gets these 300k miles in New York City - yeah, that's cool and hard to imagine.

    Up until 2 years ago when I moved to the Lowcountry of South Carolina, the car had spent most of its life in the mountains of North Carolina and I did travel a lot for work. I agree, I have little to lose doing a fluid change and will order some Mobil 3309 today. Thank you Scopeman for suggesting I reset the counter. I checked the transmission dipstick today, it was high when cold and appeared to be at the appropriate level when hot (harder to see, just a thin streak). The fluid is dark red.

    I did not know a transmission had a "balvebosy". Where is that located?
    I agree vtl, lots of highway driving and a change of fluid is at least worth a try.

    I did a cooler line fluid exchange on the XC yesterday. 211,000 and the last change was at 180,000.

    Drained the fluid from the transmission, added 3.5 Qts. Hooked up the hose, pumped out two QT, added two, and repeated the process. After about 8 Qts, the fluid, which was already red, got noticeably more clear and bright in color. I did the pump & refill twice more, for a total of 12 QT in the exchange.

    Shifts perfectly.

    It's been 100,000 miles since my valvebody work, and the regular fluid changes, along with the external cooler, have kept the transmission alive and well. I've not added a magnefine filter, but the magnetic drain plug had very, very little on after 30,000 miles, so the wear on the steels inside the transmission is minimal.

    But as I was doing this, and it took me about an hour, including getting out the ramps, removing the splash guard and doing the work, I thought of my 850 wagon, which got the first flush on the AW-42 at about 165,000. That fluid came out absolutely black and horrible. With new fluid in it, it ran perfectly for the rest of its life, despite all the old wive's tales about old fluid keeping a transmission together and the admonition not to change it completely.

    Astro, Do you run the engine to heat the ATF beforehand. Also, should I put the car in drive when doing the fluid exchange?

    I run the engine a bit. As long as the trans temp is above 100F, you'll get decent flow. It's a trade off, however, as you'll burn your arms on a variety of engine parts if it's truly hot. I put the car in every gear as I do the flush. The fluid comes out at about a quart every 15 seconds or so, you've got time to shift through the gears as it's pumping out. I shift in and out of every gear serveral times - to ensure that each hydraulic circuit gets fresh fluid.
