Hi guys, few weeks ago, had a high speed run on the highway and after the run which lasted a good 2-3 mins of full throttle. I noticed a "fast" vibration at the gearknob whenever the rpm reaches 2500rpm and 4000rpm. There were no vibration at all before the run.

The vibration present regardless the car is in gear or not. It'll vibrate when it reaches the rpm that i've stated. I've checked the mounts and apparently its fine.

Any ideas?
btw, my engine is a NV M50b25 with Getrag 260.

Thank you :cry:
