Default LT77 oil???

Just been reading Ashcroft transmissions tech stuff about this gearbox, they recommend Dexron ATF?? Is
this right, mines pissing EP90 out of every hole possible? I can tell it's EP due to colour & cat piss
smell?

Is this right or what?

ATF is correct for the gearbox, EP90 for the transfer box.

You can also put SAE 75 synthetic gear oil in the main box, this is a touch
on the sticky side in winter when the 'box is cold, but OK once it's bee
running for 10 minutes or so.

main box plus cross-drilled transfer gear (no point in fitting one without
'tother) was about 600 notes when I got one. Dunno how it rated in quality
compared to Ashcroft. Have heard one or two disaster stories about
Ashcroft, but only one or two, and considering the number they probably
shift, that's not bad.

Ashcrofts certainly know their business, although I understood that current
thinking is MTF for LT77's, ATF as an alternative?

people seem to suggest www.difflock.com as the place for fluids.

The oil pump in the gearbox is unlikely to survive cold EP90.
Recommendations have varied over the years, but always thinner than EP90.
Different oils have been recommended to get best performance for gear
changing. The transfer case is recommended to have EP90, but is not very
fussy as long as it has oil of some kind in it.

You are right. On no account should EP90 be used in LT77 or later gearboxes.
Any MTF is better than ATF but don't worry about it. My fill for the last
ten years or more has been oil recommended for Ford manual gearboxes though
for some time now LR has recommended their own MT oil which is the same one
used in Rover and Honda manual gearboxes. Its viscosity is about the same as
ATF at around the same as SAE75w.
The transfer box used in Defender and Discovery is happy with anything
vaguely wet and slippery, from 10w/30 to EP90. The thinner the oil the less
drag.

If you use ATF in the LT77 then you really need to change it every 6000
miles while a proper MTF will last at least double to 12000 miles. My
Defender has run for over 10,000 hours [about 130,000 miles with an average
of probably in excess of 10 gearchanges per mile] of heavy work with ATF at
every 10,000 miles early on [the change quality would deteriorate at
anything over 8000 miles] to running on Ford MT75 oil changed at every
20,000 miles in later years. Still changes as well as ever on its original
'boxes.

The viscosity of ATF is around SAE 20 or 25 and nowhere near 75.
