Shaking/vibrations under 2000 rpm E46 323i 99'
The whole last year I've been experienced some strange shaking/vibrations from the driveline someplace between 1800 to 2000 rpm and only when the car has some resistance. Like in small uphils. The car is equipped with an ZF automatic tranny that operates perfect.
During this year I've checked all parts in the driveline, changed alle parts with signs of wearing, but still the shaking occurs just bellow 2000 rpm.
It sounds and feels like it comes from the final drive unit, but there is a strange thing...it seems like this only occurs when the tranny is in the D-modus, and not in the S-modus.
Even if the tranny seems as good as new normaly, could it still be the problem in this case? Or is it most likely something with the final drive unit (or even something else)?
Anyone experienced something like this? Solutions?
