Anybody have any recommendations of gear oil to use for break in period? I heard of people using Redline MT-90 but curious if people have any other opinions. The transmission is brand new from Nissan.

 

Cheers.

Wasn't there a guy that mentioned having issues with running synthetic gear oil during the break-in period?

Maybe me. Transmission started whining after 3k kms at a track day.

I used the factory-filled stuff for run-in, then changed to fully synthetic Syntrans "GL4+" 75W-90 (TAF-X) at about 800kms. When my new box comes I plan to just use the Nissan GL4 75W-85 consistently.

That's because you can't get the good one in Japan, being Syntrans 75w-85 GL-4.

To be honest there's nothing wrong with vmx full time, just change it more regularly. One of the Rs we're just sticking with that - VMX-M gl-4 at $50 per 4 litres.

    • It is an absolute lottery. They can and have died at stock boost with low usage at all. The turbos are now anywhere up to 36 years old!
    • Huh, wonder why it blew then. I never really beat on the car THAT hard lol I dailyed it and the turbo blew after 6 months
    • That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php
    • Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.
    • I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.
