You can try some better trans fluid like Redline MT-85 or the Motul Gear 300, Should quiet it down some.

- I'm actually running Redline MT-85 right now
- Is this really "chatter" though? Isn't chatter when you're in too high of a gear at too low of a speed (ex: 4th gear @ 20mph)? If so, yes, I can reproduce those chatter sounds all day. But starting off in 1st, clutching out, shouldn't give chatter, especially with an OEM setup. I could be wrong...
- Transmission only has 2k miles on it. Nissan replaced it recently. The rest of the car including the stock clutch and flywheel have about 19k on it.
- If I rev up to 1300 rpm or so when taking off in 1st, I can't hear the rattle
