Hi, I'm in brussels. Mineral is more recommended than synthtetic, but i think you shoul be ok with that ATF.
For Velvet Drive and Borg Warner 71C and 72C transmissions, use Dexron IIE ATF, Dexron III ATF, or any ATF fluid which meets Detroit Diesel Allison C-4 specifications
Maybe someone else will confirm? The press was a problem for me aswell: i didn't want to purchase one for one time usage... I think you should be ok to use a bottle jack if you have something that can be used as counterweight or to lock it in place with the ring gear. You'll only really need the press for the clutch pack compression.
