Sorry if this is a repeat but I couldn't find a NC only thread about this.

What transmission oil is good to use in the NC?

I'm assuming it 75w90?

look in your glove box for an owners manual.

I used Penrite Transgear 75W-90 semi -synthetic and it works fine.

It's not really as simple as "it works fine"

The oils need to take into account the correct viscousity, too thick it wont get where it needs to go, too thin it wont lubricate enough.
They also take into account the materials inside the gearbox, not all oils are compatible with say, brass synchros.

Just going off feel isn't a way to test long life, or compatibility, I could fill a gearbox with water and it would feel fine for a week maybe, then it would eventually die.

basically, as Mr Morlock said, read the manual.

It works fine for me in that it is the correct 75W-90 viscosity and meets API service GL-4 as recommended in the Owner's Manual.

"Trans Gear 75W-90 is a premium performance, semi-synthetic transaxle oil. It meets the performance requirements of API MT-1 and GL-5 as well as many manufacturers’ requirements. It is a highly versatile product that can be used in transaxles, gearboxes, transfer cases and differentials of a wide range of passenger vehicles and 4WDs where API GL-4 or GL-5 SAE 75W-90 oils are recommended. Can be used in place of 80W-90 oils."

I've tried some Penrite stuff and while it was an improvement, I still wasn't completely happy.
The recommendation on the big forum in the US is to use the Ford Synthetic XT-M5-QS Gear Oil but it's not available locally.
I use a Product from Ford Australia which matches the same WSD-M2C200-C specification as the US Ford Product.
It's a 75W-90 spec so it matches the OE requirements for NC. Part No R1426 1L
I like the smoothness and shift feel. Works for me.
