Nismo 6mt owners: Excessive transmission chatter?

JARblue

My stock clutch ONLY chatters at low RPMs (or idle). The more throttle applied at low RPMs, the more chatter. If you're getting on the throttle at all while at 1200 RPMs (in any gear), that is lugging and definitely causing the chatter. The Z likes high revs. I make casual shifts around 3-4K RPMs, meaning my next gear engages near 2500 RPMs or so. Shifting in this manner virtually eliminates all chatter on the stock clutch in every gear except 1st.

You're just fine at 20 mph in 3rd gear. The owner's manual says you can be in 6th gear at 35 mph. I definitely don't make it a habit, but I have done a 1st to 6th shift before

Thanks Jar. Do you happen to notice if this is a temperature-related issue with your tranny, meaning, it won't happen the first few minutes of a cold start but will start chattering when it gets driven more? That's exactly the case with mine... first few minutes it's quite and no chatter even if I lug the engine. But if I lug the engine with low rpm once the car gets hot, it will chatter like I have an aftermarket clutch/flywheel
