A while back there was discussion on running ATF in the T-Case of the A440's
in FJ/HJ60's.  I have searched the archives, and it seems at the end of the
day that in Australia and Japan this is spec, and it seems to be spec in N/A
to run 90W gear lube.

There was some mention of bearings playing a roll in which lube should be
run, however I saw nothing saying if Toyota supplied different bearings for
the N/A auto t-case's.

The conversation just sorta petered out, with no real closure.

If the N/A A440's will be happy with ATF, that seems to me to be a better
way to go, in case the seal between the tranny and t-case go.

Has anyone discovered anything new to add to this discussion?

Thanks

Sorry, while I do not have personal experience with the A440F, I can add to 
the discussion that my daughter's auto-tranny 1985 4Runner does indeed use 
ATF in the t-case, and this is as the factory intended it. In fact, there is 
no seal between the tranny and t-case, filling the tranny also fills the 
t-case.

Ran three part numbers to see applications and years:

Needle Roller Bearing Transfer Output Shaft 90364-17010 used in multiple
applications from 1980 to 1999.

Idler Bearings 90364-38012 used in T-cases from 1985-1999 various
applications

Bearing, Transfer High Speed Output Gear 90364-40001 used in applications
from 1984 to 1999.

Some of the newer applications for the output shaft needle bearing is
HDJ/FZJ/HZJ 80's, HJ61, FJ70/73/HZJ73, HZJ100's.

Does anyone running one of these later model LC's have a manual handy to see
what is recommended in t-case of the auto versions, and could you post it
please?

I suppose that does not definitively answer the question, however Ian B's
research in 2002 helps.

...Not all autos got it, and I can't say why, but can guess. Remember the
old problem (pre O ring in input gear) with the oil pumping between the
gearbox and transfer case? Well...I think there was an attempt by Toyota
(putting in roller bearings and ATF) to alleviate a major problem that
could be caused by gear oil getting into autos.
So; it's not the oil, or type of oil in the transfer that is potentially
dangerous. It's the wrong type of oil getting in the auto that is the
concern. Gear oil will do quick damage to an auto.
The transfer is quite happy to run on either gear oil or ATF.
"

I guess then since the oil type in the T/C is of no great import, I'd be
running the same oil in the T/C as the gearbox/tranny."
