what type oil is best to use? I think it specifies a 50w oil
Castrol says TFC450 SAE50, 85w90? or edge 25w/50?
is this right?

Suppliers here in AU say theres no such thing is a 50w gear oil?
help!

SAE 50 seems to be consensus amongst pals here.

some advice from novak-adapt.com
When refilling your NP435 with gear oil, choose a GL-4 rated oil instead of GL-5. The latter has a higher sulphur content that is mildly corrosive to the bronze alloy synchros of the this and many other transmissions that do not have composite synchronizers. StaLube and RedLine are brands to look for, among others.

We recommend that you select a conventional lubricant or a para-synthetic in lieu of the full synthetics.

and look here for a rebuild w/SAE 50
NP435/NV4500

Thanks Al, I stumbled on that page before and could't find it again, I thought it was 50w - apparently there's a difference
So will a 25w/50 engine oil be an equivalent option?
It is a usually hot climate here except for a few cool winters mornings

no, go for the SAE 50 gear oil

such as:
SHELL; DENTAX® S Gear Oil
SAE 50
A synthetic transmission lubricant for use in automotive manual transmissions.
This synthetic holds up under extreme temperatures. Excellent stability and antiwear properties provide extended drains and long transmission life.
