Interesting. I was worried that I initialy put in 85w (I recently switched Mobil synthetic 75w)
I have two issues with my 5-speed.
The first issue is the tendency of the 1st to 2nd shift crunch. This is worse when the tranny is cold and goes away as it warms up.
I can avoid it when the tranny is cold by gently performing the shift, which I do religously now.
Putting in the 75w made the situation a little better. I would also say that over time this tendency to crunch appears to be on the
decline. Maybe as a result of the synchos breaking in? All other gears shift wonderfully.
The second item is that the tranny is a little noisy when idling and in neutral. It's a clattering noise. kinda like the tank
tread noise
you hear in old WWII movies. It's not very loud but it's louder than I expect.
If I depress the clutch the noise goes away.
I should mention that this tranny was rebuilt by Rivergate when I bought the kit a little over a year ago.

Dean,
I just happen to have a 1980 Datsun 210 service manual. The type of gear oil required in the manual is API GL-4. The
viscosity according to the viscosity chart for temp range of 100 degrees F down to -20 and beyond is 80W-90. If you are going to
operate in temps above 100 degrees F straight 140 wt.
