If anyone were to drive a car with a decent North American market ‘box and then a comparable-in-condition RoW one, apart from the lack of a fifth gear would a layman be able to ‘know’ which one he was driving? And is the real-world difference measurable?
Apparently so. I guess Nissan went to the trouble of doing it differently for that market for this reason.
But soon-ish, I will know the difference between the oils. I have to say, in comparison with what I had in the box before (which strangely smells of fish), the MT 90 makes the gears less willing to engage - which is a shame. I can only assume it’s not as viscous as what was there before. Swepco next, once I sort out the immediate issues.
I’ve got a 1973 240z with L28 block / gearbox. US car. So does that mean MT90 for me?
Really can’t say like that dude because you need to find the gearbox type / number off the side of the ‘box itself. If you can’t and want to play safe, then MT90 won’t damage either brass or steel synchros.
