Well I found out that SAE 90 is actually what is recommended, which according to my research has a standard minimum viscosity of 13.5 at 100c. The Redline High Temp ATFs min viscosity at 100c is 10. So, its probably just too thin to put in the transfer, regardless of whether its GL4 or not...
GL-4, GL-5 is a protection rating, not a viscosity spec.
I know of no ATF that qualifies as a GL-4 gear lube, because it does NOT have the level of AW protection needed to meet the GL-4 protection level.
What is "AW" protection? But Redline's website says their high temp ATF does meet the GL4...

My Jeep TC calls for ATF. But thats only a Jeep not a Land Cruiser.
Great question, but I guess the answer would be time and money! And the guys at the cruiser forum would love that next statement!

Excellent advice, thanks. Im definitely on the cruiser forums, and there are...

So I called Shell earlier this week. Spoke to a rep who said he was a chemist by trade. He said he couldnt recommend the T6 for my 03 BMW, for the 88, yes but not for the 03. He said it had never been tested against LL01 and didnt think it would happen anytime soon. (I am really curious though...

And I'm afraid you will not find it. T6 hasn't been run against the battery...

As I stated earlier, those oils no longer carry...
