Vibration after 4500 rpm?

I noticed if I accelerate fast , on the 4th gear when it reaches 4000 rpm or so the car feels like it will explode. Vibrations from engine are high and even seats shake and etc, until shifts to higher gear? Under "old lady" normal driving style,no problems,as car shifts at 2.5k-3.5k

Is it normal on 09+ ? :tdown:

I think FX 09+ transmission made to shift around 3k to drive smooth and soft
But i drive in manual mode,and like to go higher than 4k. Car wasn't really designed for it :-) I guess.

hmmm well maybe you kept hitting the rev limiter that something happened so on that specific gear change at high speeds you have a tranny slip issue? You should get your gearbox and tranny...and motor looked at. Leave it in auto for now haha.

I love my paddle shifters ;) I had my rev limiter off on the FX35 and want to do the same for the FX50...I hate the feeling of hitting the limiter and having it bounce and screw up your gear change...
