transmission problem??? help!

Hey everyone,

So last night i was driving home from the 401 and my car (2003 325ci) was making a horrible, loud clunking noise every time i excel and shift gears. It shakes the whole center console and sounds nasty constant clunking.
At constant speed of 80-90km/h its ok but when i try to excel (on ramp/off ramp) it makes the same noise and car struggled.

At first i thought it was unbalance wheel or warp rims but it got worst and wost and its coming from the center console gear knob area underneath the car.

Any suggestions or idea what it is? i am going to bring it to bimmersport soon but would like a estimate on problem and cost?

thanks!

A shredded guibo or the drive shaft bearing. If this is the problem, both are an easy fix.

I'd agree with pj3, but also add that it could potentially be a transmission mount point (if one of the mounts tears or un-bolts, it'll likely give vibration and clunking).

It might be worthwhile to consider shifter bushings if you've got to pull the driveshaft - you'd have a little more room to work (but not quite as much as during a clutch replacement).
