A friend has a 2004 Volvo V70 with 90+ thousand miles. I don't think her transmission has been touched except level checks. I don't know which engine/transmission option it has...are there automatic transmission differences in '04? Do they all use 3309 fluid? (I know, ExxonMobil makes the not-synthetic 3309 fluid for certain Aisin-Warner transmissions and bottles it under the automaker's labels...Toyota T-IV, Volvo something, GM 9986195, VW/Audi G-055-025-A2, etc.)
I'm considering recommending that she do a drain and refill at the next three or four oil changes to add longevity to her transmission. It is shifting well now. I think I'll suggest to her that she use the latest version of Mobil 1 ATF...excellent quality, moderate cost, easy to find, and a near-universal fluid that is "recommended" by ExxonMobil for transmissions spec'ed for 3309.
Does this sound like a good plan?
