XC70 Transmission flush

I have watched quite a few YouTubes on how to flush the ATF.

1: The most common method suggests draining the pan and refilling with same quantity, then draining the remainder by attaching a temporary hose to the fitting at the cooler and cycling through 2 quarts at a time.

2: A local Volvo mechanic suggested forgoing the pan drain and just attach a tube to the fitting at the cooler and cycling through drain/replace until fluid is clean and clear.

BTW, while I was at Pick and Payless, I removed the hose that goes in/out of the cooler and am thinking I could easily remove the hose on my car, attach this "spare" hose (with some clear tubing) to do #2. This would alleviate the need to get under the car, remove the skid pan, and drain the sump.

What do you think?

Also, is there anywhere in Sydney where I could buy 12 quarts of the correct ATF (3309) or should I be ordering from Amazon?

  • Whilst removing the pan, you are given the oppurtunity to clean its inside surface, replace the filter and pan gasket. This will become a more thorough job, then next time you can just drain and refill

  • Penrite atf fs

    Should be under $50 per 4L

    Takes 16L to flush



    Start engine

    2L Out

    Stop engine

    2L In

    Rinse and repeat and check the fluid level after flush completed and add as needed

    I never considered actually removing the pan, only unscrewing the drain plug. I wasn't aware that there is a pan on the AW55. I should look more closely.

    Look what I made today. (Hose is from a spare parts car)

    When I am running the engine, and collecting the 2 litres of dirty fluid, should I be working through the gears? And more specifically, should I put it in Geartronic mode and go through 1-2-3-4-5?
