Nissan OEM transmission with lower gears?

[CISO1969]

I may have the terminology wrong, but remember some First gens had a lower gearing in transmission that were coveted. Mine is one of them can't remember the terminology used is it 4.12? Any help I cant find the info on the data plate and I thought that's where it was. Need to replace transmission an d not sure if that matters

The 1st gen v6 uses the same transmission as the Z31. But all the gear ratios are different. You want to make sure you get one out of an X or Frontier. You don't want the street transmission. It'll make a slow dog slower.
