You heard correctly that Type F was the correct fluid. Both my 90 and 91 244's have, without any issues for over a year and a half now, run Dexron VI. When I made the change, I did so like an automatic trans flush; I disconnected the return line and added a couple extra feet to it with some smaller tubing(that slid inside it and held in place with a couple hose clamps) and put it into an empty milk jug. Then I made sure I opened my four quarts of Dex VI and started the car and let it draw the old fluid out of the reservoir and started adding fluid until it ran fresh fluid. Put it all back together and took it for a drive, checked and made sure the fluid still looked good(which it did). I also added inline filters on the return.

I've used Mobil 1 synthetic ATF in my 95 850 for about 6-7 years. Stopped a rack seal leak and saved me big money! Flush and replace every 2 years or so. Car has over 250k on it and still has its original rack and pump in it.

In my humble opinion, synthetic ATF should be fine in a 240.

Yep, in all the owner manuals for the years you list, the Volvo owner manual states "Type F".

Put mineral Dexron in there, as the Haynes manual incorrectly indicates in the specification, and you'll ruin the rack rather quickly, as I found out on my manual steering 1990 Volvo 240 DL wagon. Stupid, stewpid, stoopid me.

Yet other issues in Volvo doc, owner manual and factory green service manual, as to what fluid goes in that M47 manual trans - ain't "Type F", use Volvo spec oil, or Redline synthetic, or the like).

You could use a "Type F" synthetic. Yet many here use synthetic general "ATF" fluid like Mobile 1 without complaint, I guess.

Yep, you can splice in a filter on the low pressure return. Also, some will use a hanging magnet in the reservoir fluid to collect the micro metal bits.

Amsoil makes a synthetic "Type F" I use my 1991 240. Swapped the fluid out by spinning the pump pulley and draining the old oil from the low pressure return that was tipped into an oil collecting can I rigged up. Had to remove the AMM / MAF and associated piping to have access. Maybe you and other can do so mroe elegantly (without removing the AMM / MAF piping?)

Else, well, there you go.

Have you considered replacing the two hoses, specifically the high pressure hose, or having a hydraulic shop fabricate one up using the Volvo hardware at the ends?

Hope that helps.

Happy Friday (all day long)!
