I found it once before (as a previous post shows) but I didn’t post the link where I found it damnit, and my searches now turn up nothing so without evidence I’ll declare it not suitable, until I can prove otherwise. I do remember reading it, not believing it, doing the research and disproving myself, hence why it’s front of mind to me.
Just go Ravenol or RP if you can’t order LR fluid.

a quick google shows you can order direct from RP Synchromax Manual Transmission Fluid - 1 Litre – Royal Purple Australia $61.40 for 1L. I’m sure I paid less than that. Not sure how much the LR branded stuff is going for these days.

its nearly time to change fluid again, no issues running Synchromax in the Magna Steyr transfer case at all.

Performance lube is a stockist and is about 500m from my house, $25 a bottle.

I'd like to know why anyone running syncromax or LG6 in their transfer case thinks its fine?

Synchromax TF 0753 is listed as suitable on a chart I can't find again, do you think it is not?

A Royal Purple chart or a Magna Steyr chart - I would only take notice of alternative oils listed on a Magna Steyr chart.

I'm going to call in at a LR stealer on my way to Perth next week and get the genuine oil.

The oil must have an additive package suitable to cope with a variable pressure wet clutch pack as well as the usual bits , it's the same reason the oil for the e diffs is a different spec. ( maybe Rick 130 would know what the additive might be )
Either genuine oil or ravenol tf-0870 ( which you can get from Imparts Osbourne park if you're in Perth and is probably a bit cheaper)

SHELL TF0735 is the approved spec for use in these MagnaSteyr transfer cases with a wet clutch pack. RP meets the shell spec, as does ravenol and other various BMW specced oils.

Ergo to me its good to go, plus the last 45000km running RP synchromax and performing as expected, without it blowing up also tells me something is ok.

Each to their own, but in my view the LR "special oil" is overrated and overpriced, its just a transfer case.
