flushing the transmision V70-XC70 2004

Our '04 V70 2.5T has a 5 speed automatic. The car has 70,000 miles on it and the transmission fluid looks dark. The owners manual lists it as an AW5 transmission that requires Volvo trans fluid 1161540-8. Is this stuff the same as the Mobil 3309 fluid ?

All the instructions for flushing the trans oil at home say to run out two quarts, add two through the dipstick hole, and repeat until the fluid is clean. Is there a reason not to add the oil to the top fitting on the cooler to flush that out also ?

Are there any tips, tricks, techniques that will make the job easier ?

Thanks

Greg

    This is a recommended method. There are others.

      Flushing with the 2 qt method is one way. the other is a flushing kit from IPD usa.com it's easy and does a good job. BTW the mobil is the same. I've used it and it's great fluid. Don't let the fluid get dark again. change more often.

        The 2 qt method is the IPD method. The IPD kit is just a funnel and clear tubing.

    Yes, it is the same as 3309. What could be easier than pumping out 2 quarts at a time? 20-30 minutes from start to finish isn't even worthy of an extra beer!

    Somewhere along the development cycle, I was told that the output hose for the tranny moved to the bottom of the cooler. I don't know if this is a wive's tale or not, just be carefull. The amount of fluid left in the cooler is only a couple of cups and will not make a difference.

    I always bought new spring clips and O rings from the dealer rather than reusing the old stuff. I just considered it cheap insurance.

      I just did mine a couple of days ago. I agree with Klaus on the clip and o-ring where the line goes into the cooler. I didn't have this on hand and came out okay, but it would be a good idea. You'll need a funnel with a small long end or line to get down to the fill hole. The IPD flush kit i'm sure is fine and I may acquire it at some point but you can get by with a piece of fairly rigid hose available at your local home center that is 3/4" o.d. This fits pretty snug into the hole on the cooler, although it does need to be held in place while the car is running. I did it this way and didn't make much of a mess.

      Toyota T-IV fluid meets the JWS 3309 spec/requirement and is around $5.00/qt. at the toyota dealer. I used 16qts on the flush, my car is at 77k and I have no idea on the prior service history. My fluid started running clean around qts. 11-12. Good luck
