Sticky: 370Z Transmission Failures (6MT)

Wilson2608 · 06-13-2016, 01:16 PM

Mine wont engage from 1st to 2nd at high rpm sometimes. It's a hit or miss really. 6th gear always grinds unless I baby it into gear.

It definitely sounds like the synchros are going out. I don't know if a fluid change would help that. I would check to see if it's covered by warranty because I can only imagine it getting worse.

Watching this and the other thread:
Built Manual Transmission

Has anyone out there found a good source for rebuilt manual transmissions with sketchy syncros? Preferably Houston area...
