I'm partial to ZF's reputation for knowing what they're doing, so put Lifeguard in mine. I don't believe my mechanic did the above procedure (based on the amount of oil I got back), but I'll just get it done again in 30k or so by a ZF specialist...

Its a pain, only ever got 4 lts or so out, once got 6 when I let it dribble and gurgle for half an hour or so, fit new pan, pump in new oil till it runs out, replace bung, fire up and run it thru the gears including R, with engine running check level, usually pour in another litre, bung in and then run engine in 2nd @ 2000rpm for about 30 secs I think it is, check level again it's fulll when it just dribbles out the hole...... Its something like that, I have a cheat sheet on shed wall that I follow......... I use big wheel chocks, and foot on brake while giving it revs and moving selector, probably need the wheels to turn but eh!!!!, if the vehicle had some decent lift points I could have it on stands...
I think the most important bit is quickly checking the level soon as you slip it into park and the engine must be running, shut down the engine and then pop the bung you will get a face full of oil....
