New to me 08 G37S manual gearbox. First thing took it to Lube Stop to get all new slickum. They used Pennzoil synthetic GL4 75W90 in the gearbox. Should be okay per the owners manual. Everything good that afternoon and the next morning (about 65F). That afternoon (maybe 75F) I detect a little reluctance in 3rd and an unmistakable synchronizer gnash going into 5th. Slow, deliberate shifting required to avoid grinding. Same thing the next day; okay in the morning, not okay in slightly warmer afternoon. Parked the car. So, I guess I could take it back to lube stop to make sure there's enough oil in the box. I know these folks can be yahoos but these guys seemed genuinely interested in the car. It's not rocket science and I believe they drained and refilled correctly. Question - are these gearboxes notoriously sensitive to lubricant? I'm tempted to try some RedLine. Are the synchronizers known to be weak? If a different lube either something special like RedLine or genuine Nissan (can't believe that would make any difference) doesnt' work it's back to Texas Direct for some warranty. BTW this is the first time I've ever driven a true performance GT type automobile. Amazing. I'll get the gearbox straightened out one way or another.
