Assuming you're talking about the AW70 transmission. When changing the ATF, I disconnect the return ATF cooling line from the top of the radiator and clamp on a clear 3/8" I.D. vinyl hose to drain into a 2-quart jug. Start the engine and let 2 qts drain out. Stop the engine. Add 2 qts of new Dexron III by a funnel on the dipstick tube. Repeat. Repeat. Repeat. By this time 8 quarts have been replaced. Connect the cooling line to the radiator and you're good to go. ATF capacity of the AW70 is 7.8 qts.

Dextron D/M
This may not be much help but I have a 1984 UK Volvo 240 dl which I changed the fluid on some years ago. As I recall it was simply a case of undoing a drain plug on the transmission casing and refilling after undoing another nut physically higher up the casing.
Dexon IID, IIE, or III. Any Dexon III is fine, and it's what I use. -Bob, 1986 Volvo 240DL wagon

There are 32 fluid ounces in a quart. Therefore, 240 fluid ounces is equal to 240/32 = 7.5 quarts.
The reservoir is build into a power pump, twist off the cap.
