Then I came to the conclusion that my situation wasn't "gear grind," and over time hasn't really returned.

Can you confirm that the "driveline vibration" has more of a bass-like sound and feel to it? That's what it sounds like to me, at least.

I used to get it a lot more often earlier on, and I thought I did something to break the car (since I basically taught myself how to drive stick on this car).

But with how I drive it now, I can almost entirely avoid the problem altogether (as you guys said, it is pretty much reproducible).

For me in particular, the 3rd gear at 2.5-3k RPM

Hey guys,

I recommend both of you make an appointment with your dealers to get them checked out. Then, PM me with your VIN, dealer, full name, mileage, and best daytime number so I can escalate this to the customer service manager of your areas.
