Sealey VS70095
Its discontinued now which is odd. Plenty on ebay though.
The car has to be level to fill the gearbox and you need good access underneath it so it really needs to be on a lift, but you also need to get to VCDS to monitor the gearbox temperature so it can't be all the way up in the air (unless you have a USB extension maybe?). I tend to do it about 4" up in the air so I can still see the laptop but there's room to work underneath. I don't think you would be successful trying to do it on axle stands.
That's got me thinking now - it might be possible to fashion a contrivance which would replace the oil in the radiator before you put the top line back on, then you don't need to mess around underneath. Hmm...
