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?

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

to add to the abouve post I mean by the 25w/50 being a synthetic engine oil that castrol speaks of
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.
