transmission fluid reccomendations? V70-XC70

I will be flushing the trans fluid this weekend and have seen several threads on the topic. Using synthetic would be best, but in my area (midwest US) it will cost around $100. I saw on a T5 site that an aftermarket transmission compamy reccommended mixing Mobil 1 with ATF 2:1 (or vice versa). This would be much more economical. Anyone ever hear of this or try it? Or...good quality regular ATF and flush again as soon as it starts to show signs of wear. Much cheaper. This is my first automatic transmission and I plan on keeping the car for many years. Thanks for any help/experiences.

    Manual for my V70 w/AW5 says to use Volvo fluid only (lists a part number). Honestly, I think the factory's intention is to never flush the AW5.

    Thoughts?

      Hi Robert,

      70 series Models 2001 and on use a new type of transmission oil. This new oil is not compatible with any oils that are currently available on the after-market. I have seen this new type of oil used in Toyota, Volvo and Chrysler.

      If your transmission oil is low and you are under warranty take back to the dealer. They should top it off for free.

      Good Luck,

      Steven---

      Hi,

      If the container is black then it is totally synthetic. Castro makes both a fully synthetic and a synthetic blend. I recommend the full synthetic.

      Good Luck,

    Hi,

    I recommend that you do the flush your self and use Mobil 1.

    Here is how you do the flush.

    1) Buy a 24mm box wrench
    2) Get a large oil pan that can hold 4 qts of oil
    3) Heat up the transmission. Drive the car for 10 + miles.
    4) Jack up car and remove the 24mm bolt located at the bottom of the transmission.
    5) About 3.5 qts of fluid will drain out of a total of 8 qts.
    6) Refill transmission and drive the car for 5 miles.
    7) Repeat above procedure until transmission fluid is red.

    Assuming your transmission fluid is a dark brown it will take you about 12 to 16 qts of oil 3 to 4 drains (around $85 using Mobile 1) to get your transmission fluid red. About the same amount of oil a profession will use with out the labor cost.

    Next you do a regular drain at some mileage interval to keep the oil clean and fresh.

    I did the above method on my XC 2 years ago at 16k miles and have been doing regular drains to keep the fluid in top shape.

    Good Luck,

    Steven---

      Why would go through the pain and suffering instead of letting the transmission pump the old ATF itself. Check http://au.geocities.com/ozbrick850/atfflushindex.html and www.volvospeed.com for great info on DIY transmission flush. No jacking up, no drain pans, no driving, no mess.
      Happy flushing.

        Hi,

        I would not recommend letting the transmission pump the old ATF. And here are my reasons;

        1) Draining gets you 3 and ½ qts. Pumping gets you 4 qts before the toque converter goes dry.
        2) Letting the transmission run dry can cause damage to the transmission toque converter bearings.
        3) I have not been able to fill the transmission with fresh oil as fast as the transmission can pump out the old oil. It is a race that one does not necessary have to live with. The transmission can pump out 4 qts in about 30 seconds. It takes 30 seconds to add just one qt of oil (tiny fill hole).
        4) It will require you to have several people the do a pump. One to turn off the engine if the transmission goes dry. One to monitor the oil coming out of the transmission and hold the hose so the oil being pumped does not get all over the place (the oil comes out with the speed of a garden hose). And if you do a simulations oil fill the same time you do a pump you will need a person to fill the oil. Of course if you have everything set up just right you could get away with just one person doing all 3 tasks. A pain at best, I been there done that.
        5) And last you will need an extension hose so you can pump the oil into a pan that is on the ground. Also you may need to replace the 2 o-rings that seal the hose connection at the radiator.

        All you need for a drain is an oil pan, a 24mm box wrench and a jack. Drain and fill 12 to 16 qts of oil will get you the same results and a professional flush. Also been there and done that.

        Happy Flushing,

        Steven ~:-)

          There is no need for several peaople unless you need to share a six pack. One would do quite nicely. If you check the sites I suggested you find that there is no race at all and everyone is quite happy. Tranny pumps old AFT out, torque converter never runs dry, and you are standing up all the time instead of crawling under the car. But if you prefer going under...
          Happy crawling :-)

            Hi,

            Tried your suggestion twice. By the time I finished pouring 1 qt of oil down the dipstick, the toque converter ran dry. Had son behind the wheel to turn off engine and wife watched the pumping oil while I poured in the new oil. Sorry but I cannot recommend a procedure that can possibly cause more problems then it cures.

            By the way if you are ever in San Jose California drop me an e-mail. I would be more then happy to share a brew. My treat.

            Steven ~:-)

              The trick is to have a piece of clear plastic tube attached to the tranny hose and when you see bubbles you know it's time to shut the engine and add more ATF. You can never be as fast as the tranny pumping out. But I found that this method is even simpler than changing engine oil. Pity I installed Mobil 1 AFT so I don't have to touch it for another 40k.
              BTW, Thanks for the invitation I'll be glad to use it, and the second one will be on me.
              Happy suds :-)

    Why try to blend your own ATF? Bite the bullet, use the best ATF you can get (a case of 12 qts of AMSOIL retails for about $90, preferred customer less).
    You will be better off with one load of synthetic for the next 50K than 3 or 4 non-synthetic changes.
    Priced a new transmission lately?

    i'll spend the $100 (a little to stiff around there!!) it is still cheaper than tranny work. the tranny fluid "cocktail" makes as much sense as adding water to your milk to "cut down " on cost. you only do this once in 2-3 years so that works out to a few cents a day. give your volvo a treat.
