    On my 1996 850 TDI station wagon with automatic transmission - is it possible to
    empty the ATF completely by draining it from a gearbox bottom screw similar to
    the engine oil? Or is there something always remaining inside? Or are there
    models without draining screws?

  2. On my 1996 850 TDI station wagon with automatic transmission - is it
    It cant be emptied, and it has no drain plug. You need to remove a hose on
    the oil cooler, run the engine and pump out oil, fill new on, run engine
    etc. Do this to the oil has color as new oil.
    Think you can find some guides on the internet, which are quite detailed.

    Hi Niels, thanks again for your input.
    I start to understand, why the service plan has filling up for the gearbox only,
    no change. Rinsing with new oil is probably quite expensive, not to speak about
    unnecessary waste of oil. What about suctioning it out? There are these little
    car battery driven pumps with thin stiff plastic hoses. Can I get down to the
    bottom of the system through the refill opening? Then I might think about
    suction the old oil out almost completely and then just filling in new oil. Or
    is there a compartment in the system which does not drain to the lowest point. I
    have downloaded something for the 1995 850 models, but not the diesel engine. I
    am expecting "the" solution of the information shortage in my physical mailbox
    soon from the UK.
    Regards
    Viktor

    Wasnt that expensive, i bought 3 x 4 litre cans from Volvo at $40 each and
    used 10 litre totally.
    Wouldnt try to many different methods to save perhaps 4 litres of oil,
    costing 40$.

    Assuming it's the same as the gasoline engined models, which I believe
    it is:
    Most of the gearbox oil is trapped in the transmission, of the approx. 7
    litters in there, only just over 2 will sit in the bottom. There is a
    drain plug in the bottom of the transmission.
    Drain the transmission, reinsert the plug and refill.
    disconnect the top cooler hose that goes into the left tank on the
    radiator, and attach a hose to it that will reach a drain bucket
    Start the car, turn off when 2 litters come out. Refill.
    Repeat. Volvo specifies running through 16 litters this way, I find the
    fluid is clean after "only" 12.
    Have a new seal and spring clip handy to reattach the transmission oil
    hose to the rad.
